And in the document about Couch DB, it is mentioned that should configure environment with "disable remote connection" So, Only the peer can access the Couch DB?

Welcome, @robert.feng and @Daniel. As you can see, there is a lot of interest in Hyperledger Explorer, especially support for Hyperledger Fabric v1.0. We are looking forward to hearing more about the work that the Hyperledger Explorer maintainers are doing and how people might be able to lend a hand.

Hi
I want to develop an application on Hyperledger fabrics. I have bit knowledge about ethereum where it was straight forward, can develop smart contract and deploy it on the main network . But here I got confused that where to start itself.
My aim is to write a program on Hyperledger fabric. Can you please help me to find the right place to learn other than the doc.
AER_IoT (Tue, 22 Aug 2017 12:14:50 GMT):
@shivap_17 https://media.readthedocs.org/pdf/hyperledger-fabric/latest/hyperledger-fabric.pdf and the official website https://hyperledger-fabric.readthedocs.io/en/latest/build_network.html
Then I recommed you to check some examples like Marbles or other ones to better understand how the go chaincode works :)
shivap_17 (Tue, 22 Aug 2017 12:16:27 GMT):
@AER_IoT I'll go through them. Thanks a lot for your time :)

MikeMayori (Mon, 28 Aug 2017 00:52:08 GMT):
i thing the explorer is under development right now, i saw their road map 2 months ago , the state of this project is development , so it may have some errors
MikeMayori (Mon, 28 Aug 2017 00:53:01 GMT):
my advise is to wait until the team launches the version compatible with Hyperledger 1
MikeMayori (Mon, 28 Aug 2017 00:53:59 GMT):
But if you want to learn try playing with the api's first and then you may want to develop your won explorer
MikeMayori (Mon, 28 Aug 2017 00:55:38 GMT):
after learning how this api's work and be familiar with the architecture you can try de play ground which will allow you to know better all the tools

But, my PeerList is populated with only one address, and it's wrong (looks like the sample url). The other boxes are empty, no blocks, block lists, or transactions show up.

Hi All,
I am following the setup guide mentioned at https://github.com/hyperledger/blockchain-explorer
I have completed the steps until the section "set fabric docker env"; the steps in the following section "start fabric-explorer" are unclear. For example the command "cd blockchain-explorer/fabric-explorer" does not work as there is no "fabric-explorer" directory in the parent cloned folder (from Github). Additionally, the further metioned files & properties like (config.json,set channel,mysql,tls,app/network-config.json or app/network-config-tls.json) are not mentioned clearly.
Request you to please guide me on the right setup path.

@t_stephens67 When you say hlfv1 network ? Do you mean running the "Build your network" byfn.sh script ?
t_stephens67 (Fri, 06 Oct 2017 12:31:21 GMT):
no I built my own network
t_stephens67 (Fri, 06 Oct 2017 12:31:32 GMT):
its similar I think
t_stephens67 (Fri, 06 Oct 2017 12:33:56 GMT):
the connection profile is the configuration composer uses to connect to the peers, orderer, ca, etc... I was just wondering it the network-config.json could be set up in a similar fasion
t_stephens67 (Fri, 06 Oct 2017 12:48:28 GMT):
for instance it looks like its trying to connect to my peer but it says Org1MSP faid to deserialize creator identity org1msp is unknown. so I added the keyValueStore location but that didnt seem to do anything
mna2016 (Fri, 06 Oct 2017 12:56:53 GMT):
@satheeshk @t_stephens67 I think I am going to try updating the config file with the connection details. let's see what happens.
mna2016 (Fri, 06 Oct 2017 12:57:37 GMT):
blockchain explorer should work on any underlying blockchain network whether its running on cloud, containers, locally etc
t_stephens67 (Fri, 06 Oct 2017 12:58:48 GMT):
@mna2016 take note the differences between requestURL->requests eventURL->events etc....
t_stephens67 (Fri, 06 Oct 2017 12:59:49 GMT):
for instance I changed the word peer1->vp0 and it was not happy with me lol
mna2016 (Fri, 06 Oct 2017 13:01:38 GMT):
@t_stephens67 thanks for the hint. I have a connection.json(which is hyperledger composer connection profile). I am going to put those parameters in this config file.
t_stephens67 (Fri, 06 Oct 2017 13:18:03 GMT):
OH I think I know why. It uses admin and I need it to use PeerAdmin

@mna2016 I'm trying to get it running on a kubernetes cluster and it is hanging ...
t_stephens67 (Fri, 06 Oct 2017 17:20:30 GMT):
Does anyone know if the PeerList works? everything is showing and transactions are showing up real time. but the PeerList is still the template
kletkeman (Fri, 06 Oct 2017 18:16:07 GMT):
Hmmm ... making a bit of progress ... I finally got the main page (after waiting for a long time) and the channel menu even showed the name of my channel ... but I am really hampered by how slow the UI is and the fact that the UI hangs interminably and never shows any messages regarding the quality of the config, the network json, and so on. The UI is pretty, but the app is a bear ...
kletkeman (Fri, 06 Oct 2017 18:17:41 GMT):
And after at least 3 or 4 minutes, I see the channel1 title on the main page, yet there is no data at all ... and in the peerlist there is some other peer that has nothing to do with my configuration ... someone else was wondering the same thing ...
t_stephens67 (Fri, 06 Oct 2017 18:19:50 GMT):
yea that peer list is the default list.
t_stephens67 (Fri, 06 Oct 2017 18:22:37 GMT):
@kletkeman depending on how you have configured your servers you may have to go though and change localhost to your DNS in the API swagger and in a few other places to get it working properly.
kletkeman (Fri, 06 Oct 2017 18:26:17 GMT):
@t_stephens67 Thanks, but I'm not going to continue with it. The UI is extremely unresponsive, which tells me that I am never going to enjoy using it. And with all the manual steps required, it should already be running ... this looks like a case where a lot of time was put into UI design and extra features and very little put into what really matters ... running outside of the toy network it comes with. This is so common that I can't even fault anyone all that much :-)
t_stephens67 (Fri, 06 Oct 2017 18:31:54 GMT):

yup
t_stephens67 (Mon, 09 Oct 2017 12:15:02 GMT):
I made calls using the composer rest server and everything seemed to be updating on the explorer tool. The only thing that wasnt working was the PeerList still had the template peer in it instead of my 3 peers in the channel
t_stephens67 (Mon, 09 Oct 2017 12:15:22 GMT):
Also a lot of the API stuff wasnt working

Does the format of the network-config file need change?
mna2016 (Mon, 09 Oct 2017 12:20:27 GMT):
@t_stephens67 can we simple put the connection.json file inside of "/app" sub-directory
mna2016 (Mon, 09 Oct 2017 12:20:55 GMT):
@t_stephens67 by connection.json i meant the connection profile created by composer
t_stephens67 (Mon, 09 Oct 2017 13:02:53 GMT):
yea you can just replace the requests and events with the connection.json stuff
satheeshk (Mon, 09 Oct 2017 13:04:24 GMT):
`network-config.json` holds information on how to connect to your fabric network
t_stephens67 (Mon, 09 Oct 2017 13:04:32 GMT):
That should work for the "key" and "cert" what I did was point it to the same crypto-config folder as my network
satheeshk (Mon, 09 Oct 2017 13:05:32 GMT):
@mna2016 I am not sure about the format of `connection.json` used by composer..
t_stephens67 (Mon, 09 Oct 2017 13:06:01 GMT):
@satheeshk its the same only the json is worded a bit different
satheeshk (Mon, 09 Oct 2017 13:06:58 GMT):
if thats the case, replacing network-config.json to connection.json should be enough ?
t_stephens67 (Mon, 09 Oct 2017 13:07:14 GMT):
yup
satheeshk (Mon, 09 Oct 2017 13:08:27 GMT):
and the certificate location in that file uses absolute or relative pathing ?
mna2016 (Mon, 09 Oct 2017 13:08:51 GMT):
@satheeshk @t_stephens67 That's the first thing i tried. i copied in connection.json into the /app subirectory. and then renamed it to 'network-config.json'
mna2016 (Mon, 09 Oct 2017 13:09:13 GMT):
But this approach did not work. And now I am editing network-config.json manually.
t_stephens67 (Mon, 09 Oct 2017 13:11:35 GMT):
right you cant copy it word for word
satheeshk (Mon, 09 Oct 2017 13:12:37 GMT):
@mna2016 @t_stephens67 oh.. ok... i get it..
mna2016 (Mon, 09 Oct 2017 13:14:04 GMT):
Well this may sound a silly question. How to run the app. I am entering "node main.js". config.json does not say much. Is this the right way to run the app?
satheeshk (Mon, 09 Oct 2017 13:15:05 GMT):
@mna2016 Yes.. thats the right way.. in fact thats what the start.sh does..
t_stephens67 (Mon, 09 Oct 2017 13:21:26 GMT):
./start.sh will just run it in the background with no output to console
t_stephens67 (Mon, 09 Oct 2017 13:22:35 GMT):
pro tip sudo netstat -lpn | grep :8080 then sudo kill -9 pid# .... you will thank me later
t_stephens67 (Mon, 09 Oct 2017 13:22:52 GMT):
considering it doesnt have a ./stop.sh
t_stephens67 (Mon, 09 Oct 2017 13:30:43 GMT):
really cool though I ran the curl command that composer rest server gives me in a bash script that runs it 100 times then ran that in 4 terminals. since I am running a kafka-based orderer I got back 100 blocks and 400 transactions.
satheeshk (Mon, 09 Oct 2017 13:35:07 GMT):

mna2016 (Tue, 10 Oct 2017 08:47:21 GMT):
there is a syntax error in the json of network-config_tls.json. I guess the "requests" error is most likely due to that.
lclclc (Tue, 10 Oct 2017 08:47:49 GMT):
I also assume there is a syntax error
lclclc (Tue, 10 Oct 2017 08:48:23 GMT):
But all I can know is it is a valid json, I don't have a syntax validator based on configuration rule.
mna2016 (Tue, 10 Oct 2017 08:49:28 GMT):
@dolanor if I set tls=false on the config file, I am getting "PEM encoded certificate is required" error. Do you have an idea how to get around it?

@lclclc @t_stephens67 was able to connect to the composer network from blockchain-explorer

How can you do that, can you share your configuration file? Have you conquer any problem?

I haven't tried myself..
satheeshk (Tue, 10 Oct 2017 10:00:18 GMT):
From what I gather, you should modify the network-config.json in explorer from the connection.json file from composer..

[ ](https://chat.hyperledger.org/channel/blockchain-explorer?msg=oJEcFDhbcnWZLmsXW) @satheeshk Thanks for replying. I did also use connection.json and it is inadequate to fulfill the network-config.json. Some fields are missing, like organization name, certificate address....

@amazingguni How are you bringing up the network ? Can you check the version of hyperledger images you are using ? This error says that the it doesn't have the root cert to verify.
t_stephens67 (Tue, 10 Oct 2017 13:20:04 GMT):
@lclclc Yes you are having the same issue as @mna2016 where it can not read property 'requests' of undefined. If I can find some time I will find the files I modified and compare them to see what I changed. I had to modify some of the code to get it to work.
satheeshk (Tue, 10 Oct 2017 13:20:31 GMT):
@amazingguni Please share the output of `docker images | grep hyperledger`
satheeshk (Tue, 10 Oct 2017 13:21:47 GMT):
@t_stephens67 can you do a git diff or submit a patch ?
t_stephens67 (Tue, 10 Oct 2017 13:29:26 GMT):
try taking out the "server-hostname" field
t_stephens67 (Tue, 10 Oct 2017 13:31:59 GMT):
I changed a bunch of other stuff trying to get it to work last friday but I must have changed it back because it wasnt showing up in git diff
t_stephens67 (Tue, 10 Oct 2017 13:36:27 GMT):
I changed username on line 359 of helper.js from username: 'peer' + userOrg + 'Admin' to username: 'admin', then I set my network-config file the same as yall without the "server-hostname" field in the orderer and in the peers, I pointed the key and cert to the composer key and certs then changed "mychannel" in config.json to "composerchannel".
CodeReaper (Tue, 10 Oct 2017 14:04:58 GMT):
Hey, so I was going through the explorer and noticed it uses mysql database to store all details such as transaction listing and blocks similarly. In real there will be many such node applications interacting with blockchain network(same channel) How will transactions done by a separate node app emit any event that other node apps can catch and store those details in their mysql database???
gstremote (Tue, 10 Oct 2017 14:13:32 GMT):
[ ](https://chat.hyperledger.org/channel/blockchain-explorer?msg=nNBHrJNLoct7BwLcQ) @Pardha Yeah, kind of, like a way that I could track the blocks
satheeshk (Tue, 10 Oct 2017 14:57:46 GMT):
@CodeReaper its looking for are new transaction events and new blocks .. so when a transaction is successful an event is fired and captured here irrespective of which node apps perform this transaction
gstremote (Tue, 10 Oct 2017 15:00:20 GMT):
[ ](https://chat.hyperledger.org/channel/blockchain-explorer?msg=aPZdWAQytuvB6MNZN) @gstremote When I make a transaction, is there an automatic process that records the previous 'hash' of some asset in some place?
For example, when I transact one asset from member A to B, Is there a way to track the transaction of my asset ? (Obs. I'm using composer and rest server)

@t_stephens67 After fixing the json error ( a missing comma), I got node main.js" to work and I could see empty UI of the blockchain-explorer. Although the main.js run was showing too many errors and warnings. I presume that I did not use properly values in tls certificate fields on the network-config.tlsca.json file. In some time I will try to incorporate the suggestions you just gave.

I would like to get them resolved..so that others don't have to face the same issue
Pardha (Tue, 10 Oct 2017 17:23:20 GMT):
@gstremote this seems to be a business level requirement. Your chaincode needs to keep track of some sort of identifier to maintain the audit trail for the asset. So far, blockchain explorer doesn't have this capability.

any suggestions are welcome
t_stephens67 (Wed, 11 Oct 2017 19:36:07 GMT):
@matanyahu network-config.json must point to the same certs that the network is deployed with
matanyahu (Wed, 11 Oct 2017 19:45:14 GMT):
@t_stephens67 : I redirected cert paths in network-config.json from the original path (/fabric-docker-compose-svt/crypto-config) to the one generated by byfn in blockchain-explorer/first-network folder (../first-network/crypto-config), with same results
matanyahu (Wed, 11 Oct 2017 19:47:43 GMT):
unless there is another network-config.json file somewhere
matanyahu (Wed, 11 Oct 2017 19:47:48 GMT):
which is used by the app
matanyahu (Wed, 11 Oct 2017 19:48:00 GMT):
but from what I see in github, that's the one which is used
matanyahu (Wed, 11 Oct 2017 19:54:09 GMT):
I made modifications to network-config-tls.json

t_stephens67 (Thu, 12 Oct 2017 12:39:18 GMT):
@matanyahu whatever path you put as the "key" and "cert" gets appended to the current "blockchain-explorer" path so you need totake that "../first-network/crypto-config" and put it inside the blockchain-explorer folder
matanyahu (Thu, 12 Oct 2017 13:50:16 GMT):

Very strange thing. I am running example network coming along with explorer. Explorer can recongnize only 2 peer(Actuallay It should recognize 4 peers), and only one peer in peer list. It is a normal behavior or a bug, I don't see error in output log.

I have change some configuration but I have revert them back, I double check that config.json and app/network-config.json are exactly the same as what they are in github repo. And the explorer is bootstrapped normally, except the behavior I found.
Pardha (Fri, 13 Oct 2017 03:25:15 GMT):
Ok. seems like a bug.. @satheeshk --> Please check this out
lclclc (Fri, 13 Oct 2017 03:26:19 GMT):
I think, even I change something I don't know, explorer lists 2 peers and only shows one peer is still a bug.
lclclc (Fri, 13 Oct 2017 03:26:32 GMT):
And no hints to fix it.
Pardha (Fri, 13 Oct 2017 03:28:09 GMT):
agreed.. it is a bug.. I know it doesn't query the network to find the actual number of peers.. but, it should at least display what's in the config.. will look into this

I see the same (only 1 peer). I tried against the BYFN network example. It's also not showing me any blocks or transactions. Funny thing is that 2 days ago, I was able to install the explorer and browse transactions quite well.
lclclc (Fri, 13 Oct 2017 05:18:54 GMT):
So it is common case and can be reproduce.

jgiron (Fri, 13 Oct 2017 07:41:56 GMT):
@lclclc The error is in the file /explorer_client/js/index-gen.js in line 94121, the peer of example it is hardcoded.
jgiron (Fri, 13 Oct 2017 07:43:43 GMT):
@lclclc No, I am using the fabric-docker-compose-svt network
lclclc (Fri, 13 Oct 2017 08:39:33 GMT):
What it is hardcoded
lclclc (Fri, 13 Oct 2017 08:39:54 GMT):
It shouldn't know it is running on top of an example network.
lclclc (Fri, 13 Oct 2017 08:40:10 GMT):
Why it is hardcoded?
lclclc (Fri, 13 Oct 2017 08:45:33 GMT):
@jgiron, it will always show 1 peer in any network?
jgiron (Fri, 13 Oct 2017 08:46:11 GMT):
yes, and always show the same peer of example
jgiron (Fri, 13 Oct 2017 08:48:13 GMT):
Even if you change your network and you have 2 peers and 1 org called org4, the peerlist show the same as in the example
lclclc (Fri, 13 Oct 2017 08:49:04 GMT):
So every user will meet this, no matter what network they use.
lclclc (Fri, 13 Oct 2017 08:49:17 GMT):
I am wondering, why only little user like us notice this.
jgiron (Fri, 13 Oct 2017 08:50:54 GMT):
In my case I have never run the example network and i see the peer of the example
lclclc (Fri, 13 Oct 2017 08:52:54 GMT):
I personally think this is a fatal error, because no matter what user will always see wrong peers under any condition.
jgiron (Fri, 13 Oct 2017 08:53:54 GMT):
Yes i think so
jgiron (Fri, 13 Oct 2017 08:57:29 GMT):
and I've noticed that not hold more than one organization, because in the path of keyStoreValue defined in config.json only generates keys for the first organization, If I am wrong I would like someone to confirm my. Thanks!
lclclc (Fri, 13 Oct 2017 09:00:08 GMT):
That is also my observation result.
lclclc (Fri, 13 Oct 2017 09:01:01 GMT):
Even 2 orgs of 4 peers, only 2 peers are aware of, and only one peer shows up.
jgiron (Fri, 13 Oct 2017 09:07:42 GMT):
Yes, If you find a solution to this problem please let me know, I'm going to continue working in this.
lclclc (Fri, 13 Oct 2017 09:20:03 GMT):
Let's keep in touch
parags (Fri, 13 Oct 2017 09:25:03 GMT):

I set my network config (orderer, peer, ca, certs..) in `app/network-config.json` and pointed to a channel in `config.json`, but I can only see transactions of type "ENDORSER_TRANSACTION". Is this the normal behaviour?

@joaquimpedrooliveira which username and password did you use in the config.json?

admin, adminpw
joaquimpedrooliveira (Tue, 24 Oct 2017 12:39:47 GMT):
because I'm pointing to a network generated by Hyperledger Composer
joaquimpedrooliveira (Tue, 24 Oct 2017 12:46:28 GMT):
I was also expecting to see the assets and participants in a more user-friendly way, instead of a JSON :)
t_stephens67 (Tue, 24 Oct 2017 12:48:01 GMT):
@joaquimpedrooliveira you can view the assets and participants with explorer?

where at?

@t_stephens67 , select a transaction in the block widget and, in the transaction widget, click in the icon with two diagonal arrows.

How a Block is created and linked into the Blockchain, in Hyperledger Fabric ?
In bitcoin,
1. A fixed no. of txns constitute a Block
[ Block => Block no. + Previous Block's Hash + Txns + x(sealing no., a puzzle need to solve in Minning process)
2. Minning is done to solve the puzzle , and to Seal the Block [ time taken : 10mins approx ]
3. After this, all peers verify the Sealed Block (i.e., Minning process)
4. This Sealed Block gets appended to the Blockchain
In this way, Block Creation is done; Proof of Work Consensus Algorithm is applied; And finally, Block gets chained to the Blockchain
How this works in Hyperledger Fabric ? [Note: I have gone through the Txn Flow of Hyperledger Fabric, but could not find these]
[1-3]Block creation related
1. How a Block is created ?
2. Block has only 1 txn ? (if no, how we can use this in IOT then, where instant response is the need, i.e., highly efficient protocol)
3. Block has fixed no. of txns ?
[4-6 related to Consensus Algo]
4. How Consensus Algorithm works (even at the time of malicious entities)
5. What if endorsers cheats?
6. What if 51% of the peers of a channel are malicious ?
[7-8 Hashing & Sealing of Block]
7. Are we using similar Sealing of Blocks(Minning)? Solving puzzles or Simple Hashing is applied ??
8. How efficient is Hyperledger Fabric, in terms of validating a brand new Transaction ?
(from txn proposal to txn being appended to the Blockchain )
[Security]
9.As, Solving a puzzle in Bitcoin Blockchain is making the system Computationally-Secure, so that malicious parties(having <51% network's computational power) can't break it.
How secure is Hyperledger Fabric ??
t_stephens67 (Thu, 02 Nov 2017 14:58:36 GMT):
@UtkarshSingh look up the Kafka based ordering service for hyperledger fabric. The block size is determined by the rate of transactions to a max size or a batch timer. With this a block could have 1 txn or a size you specify (if the size isnt met by the batch timer the block wont be full)
t_stephens67 (Thu, 02 Nov 2017 15:01:31 GMT):
@UtkarshSingh Additionally bitcoin and etherium are both permission-less block chains meaning anyone can jump on and start. With hyper-ledger fabric the blockchain is permissioned so the peers will need to be verified before allowing them access to the blockchain. Look at hyperledger as more of a business solution rather than an open thing anyone can jump on.

[ ](https://chat.hyperledger.org/channel/blockchain-explorer?msg=yfJAyRgiexwH3uonb) @jjmiranda You are seeking in the wrong place. That folder is used to store the imported private/public key. The keystore and signcert folder is inside your network folder. If you are using sth like "first-network", you can just search "msp" in that folder, you will see keystore and signcert of an admin user in crypto-config folder, that is what you need to copy, also, you need to use "identity import" command to import them into that .composer-credentials folder.

It should work. you can try to start with fabric-docker-compose-svt. before that stop first-network "./byfn.sh -m down -c mychannel" and follow these steps. 1. `cd fabric-docker-compose-svt`
2. `./download_images.sh`

@jeevas I setup fabric environemnt on aws instance and all dockers run without any problem. Now what I want to try is to setup blockchain explorer on my subdomain and connect with my aws blockchain network. Is it possible through blockhain explorer?

For all the beginners out there, like me. I would strongly recommend you all to go through a course, titled, Blockchain for Business - An Introduction to Hyperledger Technologies, on edX
It will help you in building and visualizing the concepts.

[ ](https://chat.hyperledger.org/channel/blockchain-explorer?msg=3FRiQz9cNDX24a3f5) @MohammadObaid Connecting to a fabric network on AWS is not any different from connecting a locally, as long as the blockchain explorer nodejs backed-end can talk to fabric network via grpc then everything will work fine. Please make sure you update the network configuration network-config.json accordingly to point to right peer ip/port and crypto artifacts

Hello Everyone, I'm trying to setup Blockchain Explorer following the steps stated in Github.
-------------------
#1. cd first-network
#2 ./bootstrap-1.0.2.sh
#3 mkdir -p ./channel-artifacts
#4 ./byfn.sh -m generate -c mychannel
#5 ./byfn.sh -m up -c mychannel
-------------------
I am getting errors at Step #5 where I'm not able to create the channel (it results in a error).
Has anyone been through the same problem before or knows how to fix it?
I'd be grateful if I could get some info regarding this issue.
Thanks beforehand. -Anish
I've added the error log below.

I tried to modify config.json to either use or not to use tls but in both cases the launch of explorer failed
matanyahu (Fri, 17 Nov 2017 21:02:44 GMT):
what is weird is that explorer tried to obtain certs from fabric-docker-compose-svt/crypto-config instead of first-network/crypto-config
matanyahu (Fri, 17 Nov 2017 21:02:58 GMT):
I copied certs generated by .byfn.sh to fabric-docker-compose-svt/crypto-config
matanyahu (Fri, 17 Nov 2017 21:04:07 GMT):
I see that tls is enabled in the byfn network configuration within docker-compose-cli.yaml

the folder /tmp/fabric-client-kvs is empty

I made sure that generated certs are correct but still my deployment fails

any help with the above would be greatly apprecaited
matanyahu (Fri, 17 Nov 2017 22:49:07 GMT):
I have impression it is somehow related to an inability to interpret certificates generated by cryptogen when ./byfn.sh is executed

paths to certs are correct

@glotov the data_hash is hash of transactions in this block , the previous_hash is hash of all data in previous block. Actually a block can not have its own hash in it, because before hash you need to know all data of the block include the hash.

@RocMax , I agree with your reasoning. I meant that blockchain explorer should calculate and show the current_hash, so that people could clearly see the link between blocks.

@jfodale Yes, it was unable to communicate with CA. Solutions (1) Ensure you have all correct certificates in place or delete all and generate new certificates e.g. "crypt-config" & "artifacts" folders (2) Try with docker-compose-svt. Let me know if this solves your problem or not

All other explorer APIs provides the information respective to specific repositories..But I need all transactions (different APIs) in one call....
jasoncys (Fri, 01 Dec 2017 05:22:38 GMT):
[The answer is yes. You need to update two files in the explorer directory: config.json and app/network-config.json. Be mindful of the location of the .pem and _sk files for "admin". Good luck.](https://chat.hyperledger.org/channel/blockchain-explorer?msg=aSsrQ5jvGGorKCqjZ) @mbharadwaj

jasoncys (Fri, 01 Dec 2017 14:17:40 GMT):
[ ] In config.json, change the "channelsList" to ["composerchannel"] or the channel name you created using composer, and set "enableTls":false. In app/networkconfig.json, update "admin" {"key": "keystore", "cert": "signcerts"} and copy those two folders to the explorer working path. Hope it helps.

rajeev20 (Fri, 08 Dec 2017 17:46:34 GMT):
I can't hard code `int` `invoke` command like `chaincode example`(as shown in blockchain explorer instruction). Because i have to give inputs from keyboard.
rajeev20 (Fri, 08 Dec 2017 17:54:22 GMT):
[ ](https://chat.hyperledger.org/channel/blockchain-explorer?msg=oJh5PJnLeay94ZcDc) @Dan I just want to use different chaincode in blockcahin explorer. In which i can give the values in chaincode from keyboard.

Hi... I am new to the whole Blockchain thing.. and currently trying my hands on "Hyperledger Fabric". I have installed it in my own Amazon EC2 server (Ubuntu 16.x). I have come to know about "hyperledger Explorer" , which is supposed to provide a nice UI for the underlying blockchain.
The only problem I have is : how to open "Hyperledger Fabric Explorer" from outside the linux box ? All the examples / videos I have come across so far opens the UI in localhost. But, I can not do the same (or not willing to). If I want to access the UI from my laptop (say), what steps I need to follow ? Any help will be much appreciated ..

It does not show any blocks or transactions data for channel bar but it shows it for foo. There are two channels in the network
muasif80 (Wed, 20 Dec 2017 04:19:36 GMT):
The example network in java sdk
satheeshk (Wed, 20 Dec 2017 04:20:08 GMT):
are you able to select the bar channel from the drop-down on top right corner ?
muasif80 (Wed, 20 Dec 2017 04:22:32 GMT):
Yes
muasif80 (Wed, 20 Dec 2017 04:22:52 GMT):
it refreshes the screen and foo channel info goes away but bar channel info does not come up
muasif80 (Wed, 20 Dec 2017 04:23:04 GMT):
If i select foo back it refresh screen with foo info
muasif80 (Wed, 20 Dec 2017 04:23:44 GMT):
The real question might be that whether blockchain explorer supporting multiple channels or is there any issue with it right now. I have pull latest after seeing the above info
muasif80 (Wed, 20 Dec 2017 04:24:03 GMT):
Rigth now doing some updates to config and will try with bar channel again.
satheeshk (Wed, 20 Dec 2017 04:24:22 GMT):
It does support multiple channels..
muasif80 (Wed, 20 Dec 2017 04:24:23 GMT):
When i make it only one channel config still it did not work anyways I will share with you what i am doing.
satheeshk (Wed, 20 Dec 2017 04:24:53 GMT):
Can you please check the logs from the repo root folder ? Does it have any error wrt missing user context ?
muasif80 (Wed, 20 Dec 2017 04:25:00 GMT):
1. I copied e2e_2Orgs certs in this block_chain explorer
2. updated config.json
3. updated network_config (which is perhaps not needed now)
muasif80 (Wed, 20 Dec 2017 04:25:20 GMT):
I am doing updates to these config as soon as I am done and run it i will share in few minutes
muasif80 (Wed, 20 Dec 2017 04:39:34 GMT):
@satheeshk I have log but how can i attach it here?
muasif80 (Wed, 20 Dec 2017 04:40:23 GMT):
Ok the logs are shared here.

Because we removed the netwrok_config.json, and it shouldn't exist anymore.. also please check if the peer in java sdk network is TLS enabled

@jeevas thanks for your work! @lautroy @satheeshk I am testing new version. Seems like there is still some issue with peerlist, in my project it keeps writing more and more peers info into database. I am checking settings and source code about this. by the way, now explorer can show peerlist in real-time doesn't it? but according to the source code I think it only adds new peers, if one peer offline can explorer show the change?
muasif80 (Wed, 20 Dec 2017 12:38:33 GMT):

[ ](https://chat.hyperledger.org/channel/blockchain-explorer?msg=E8yfDk9HKN2pfWcYT) @labcoinpoc The netowk discovery part is being worked on by both Fabric and NodeSDK team. This work is dependent on fabric network (https://jira.hyperledger.org/browse/FAB-5451) . Once that is implemented will apply in blockchain explorer.

I edited the first-network files and trying to create a 2 org 4 peer network. According to the startup and docker it appears that there are 8 peers running (2 in each org). However Blockchain explorer only shows 1 peer. (peer0.org1). Even if I do a new server new install with everything default, it still only shows 1 peer. Is that normal? Is there somewhere I am missing to connect the additional peers?

[ ](https://chat.hyperledger.org/channel/blockchain-explorer?msg=Miosgw6gdng3S4mhD) @mastercpt This is the normal behaviour now. Explorer will only show the peer that it is connected to. Once the network discovery part is completed, it will be able to show all the peers

Hello Everyone... I was doing the lab assignment for Hyperledger Composer
doing a sample tutorial-network business network and stumbling upon while doing the trnsaction
wondering if anyone could help me understnad the issue.. i have been trying from past 1 hour trying different approach, but none of them are working
this is my CTO
*
* My commodity trading network
*
namespace org.acme.biznet
asset Commodity identified by tradingSymbol {
o String tradingSymbol
o String description
o String mainExchange
o Double quantity
--> Trader owner
}
participant Trader identified by tradeId {
o String tradeId
o String firstName
o String lastName
}
transaction Trade {
--> Commodity commodity
--> Trader newOwner
}
here;s my logic.js
function tradeCommodity(trade) {
trade.commodity.owner = trade.newOwner;
return getAssetRegistry('org.acme.biznet.Commodity')
.then(function (assetRegistry) {
return assetRegistry.update(trade.commodity);
});
}
and here's ACL
rule Default {
description: "Allow all participants access to all resources"
participant: "ANY"
operation: ALL
resource: "org.acme.biznet.*"
action: ALLOW
}
rule SystemACL {
description: "System ACL to permit all access"
participant: "ANY"
operation: ALL
resource: "org.hyperledger.composer.system.**"
action: ALLOW
}
using the REST server
here's my Data Source for: Trader
[
{
"$class": "org.acme.biznet.Trader",

"lastname": "TID1"
},
{

"commodity": "Symbol1",
"newOwner": "TID2"
}
Error: chaincode error (status: 500, message: Error: Instance Symbol1 has a property named owner which is not declared in org.acme.biznet.Commodity)
This looks like quite straight forward to me, but not sure what am I missing here...? Please help

Hi folks. Just brought up Explorer for the first time on Ubuntu but I'm using a fabric instance that I setup in another directory tree. The directory paths in config.json for the admin key and cert seem to be interpreted as always relative to the Explorer folder even if they have a leading / Is there a way to specify a fully qualified path in config.json ? PS I've worked around it for now by creating a symbolic link in my Explorer folder

I completely admire the ease with which this project easily setup. Kudos to the team. However, I had a code cleanup suggestion to remove the `first-network` directory from the existing repository and rather add sufficient documentation on how to bring up `fabric-samples` and use explorer with it. Filed it in JIRA BE-113

Hi @RyanLe 2 , currently historical data is not available in the graph. It just shows the txn/interval or block/interval. However we have some story items planned to query the historical data in the graph.

chave070 (Thu, 25 Jan 2018 17:28:40 GMT):
@vkblue another question,
When you change channels does everything in the explorer update? For example, the block max number, the peerlist, the transaction history.
vkblue (Thu, 25 Jan 2018 17:29:56 GMT):
[ ](https://chat.hyperledger.org/channel/blockchain-explorer?msg=4gydASPFHQw9eKwGk) @chave070 Yes, but dont think it is updating correctly tho. Peer list shows all the 12 peers in all the channels.

[ ](https://chat.hyperledger.org/channel/blockchain-explorer?msg=NtNQM2gqhX69jz4Sv) @hanumankumarn did you try port 8087 on aws (i.e AWS_IP:8087 ) ?
Amir (Mon, 05 Feb 2018 08:02:13 GMT):
also check if the container is up and running, according to the doc it should be on port 8080, but did you used cello to deploy on aws ? if that is the case in the host node list containers (`docker ps`) and look the explorer service provider and its related port. port 8080 is used by cello dashboard

Response from attempted peer comms was an error: Error: Failed to deserialize creator identity, err The supplied identity is not valid, Verify() returned x509: certificate signed by unknown authority (possibly because of "x509: ECDSA verification failure" while trying to verify candidate authority certificate "ca.org1.example.com")..

@Srini 86 did you configure to a network? and do you start that network with your channel name? and in config.json you configured the path to your network?
Srini 86 (Sun, 18 Feb 2018 14:04:48 GMT):
@nfrunza I am following https://github.com/CATechnologies/blockchain-tutorials/wiki/Tutorial:-Hyperledger-Fabric-v1.1-%E2%80%93-Create-a-Development-Business-Network-on-zLinux with four orgs instead of three. I have completed all the steps until Update Anchor Peers https://github.com/CATechnologies/blockchain-tutorials/wiki/Tutorial:-Hyperledger-Fabric-v1.1-%E2%80%93-Create-a-Development-Business-Network-on-zLinux#update-anchor-peers
Srini 86 (Sun, 18 Feb 2018 14:05:19 GMT):
and then installed Explorer, I am able to see the channel name but no peers
Srini 86 (Sun, 18 Feb 2018 14:13:32 GMT):
@nfrunza and in config.json you configured the path to your network? yes, I have added all four orgs with tls_cacerts and other attributes. Is there any specific attribute for the network path?
nfrunza (Sun, 18 Feb 2018 14:41:20 GMT):
@Srini 86 we support https://github.com/hyperledger/blockchain-explorer i do not have knowledge of the other tutorials
Srini 86 (Sun, 18 Feb 2018 15:39:10 GMT):
@nfrunza I am following the steps in https://github.com/hyperledger/blockchain-explorer to setup the explorer.
Srini 86 (Sun, 18 Feb 2018 15:39:58 GMT):
I was able to bring up sample network in the explorer, but when I created my own network with a new channel, it is not showing up
nfrunza (Sun, 18 Feb 2018 18:16:27 GMT):
@Srini 86 if you do not see the peers mean in config.json path is wrong, search for "fabric-path" and update to you network
nfrunza (Sun, 18 Feb 2018 18:18:41 GMT):
@Srini 86 follow up http://hyperledger-fabric.readthedocs.io/en/latest/build_network.html

aviralwal (Tue, 20 Feb 2018 09:50:18 GMT):
[ ](https://chat.hyperledger.org/channel/blockchain-explorer?msg=Jd32GJLNtCAhunoEJ) @sravs in the `config.json`, check if you have used grpcs or grpc and that the peer certificate passed is the correct one. This error is either due to incorrect tls certificate passed or that there is no tls security in grpc. First check the certficate passed in tls. If that is correct then use `grpc` instead of `grpcs`

cbf (Fri, 23 Feb 2018 18:02:34 GMT):
installing mysql was a minor challenge (had not done that in ages) but the rest was a cake walk... would be even nicer if it could be installed via npm rather than git clone
cbf (Fri, 23 Feb 2018 18:03:49 GMT):
the other piece of feedback would be to be careful about referencing the 'latest' docs - you may want to explicitly reference the version of the docs that represents a specific release against which it has been tested

As per the capabilities mentioned at - https://www.hyperledger.org/projects/explorer - through hyperledger-explorer we can view, invoke, deploy or query blocks, transactions and associated data, network information (name, status, list of nodes), chain codes and transaction families, as well as any other relevant information stored in the ledger. I have successfully installed the explorer following the instructions given at https://github.com/hyperledger/blockchain-explorer. But I can see only view optoins for PEERS, BLOCKS, TRANSACTIONS, etc., but there is no option for deploy, query or invoke. Looking for help on this from the fellow members of this group.

That is the encrypted data, and is being encrypted before storing into the chaincode(smart contract)
nfrunza (Thu, 15 Mar 2018 17:58:43 GMT):
I need to verify
nfrunza (Thu, 15 Mar 2018 18:00:28 GMT):
The encryption key is not always shared it depends on the chanicode and parties on transaction
nfrunza (Thu, 15 Mar 2018 18:00:28 GMT):
need verification
nfrunza (Thu, 15 Mar 2018 18:01:20 GMT):
Take a look at the : http://hyperledger-fabric.readthedocs.io/en/latest/fabric_model.html#chaincode
nfrunza (Thu, 15 Mar 2018 18:02:40 GMT):
To further obfuscate the data, values within chaincode can be encrypted (in part or in total) using common cryptographic algorithms such as AES before sending transactions to the ordering service and appending blocks to the ledger. Once encrypted data has been written to the ledger, it can only be decrypted by a user in possession of the corresponding key that was used to generate the cipher text. For further details on chaincode encryption, see the Chaincode for Developers topic.

@nfrunza I think what is stated in ( http://hyperledger-fabric.readthedocs.io/en/latest/fabric_model.html#chaincode) is the privacy of the chaincode not the data on the blockchain. it seems what is actually written in the chain is the raw data. and the numbers from @MasthanbeeShaik_123 image seems an ascii code (I may be wrong but that is what it looks)
Amir (Thu, 15 Mar 2018 23:42:22 GMT):
if you change the numbers to char you will find this string "miracleseft-blockchain"

SSL3_GET_RECORD:wrong version number. Is there someone meet the problem?
nmarcetic (Mon, 02 Apr 2018 11:09:43 GMT):
Hey folks, is it possible to run explorer just with [fabriic-samples/chaincode-docker-devmode](https://github.com/hyperledger/fabric-samples/tree/release-1.1/chaincode-docker-devmode) ? This docker-compose-simple.yaml works like a charm and its minimal fabric components set for [chaincode development according to documentation](http://hyperledger-fabric.readthedocs.io/en/release-1.1/chaincode4ade.html#install-hyperledger-fabric-samples). It would be very useful to run explorer also (even out of docker-composition). So I am curious is it possible at all ?
nmarcetic (Mon, 02 Apr 2018 11:11:56 GMT):
Looks like explorer is broken on master branch I am getting errors like `[2018-04-02 13:02:10.352] [ERROR] Query - Error: Missing userContext parameter ` Also I don't see how [explorer serve's the client code (e.g the UI) at all](https://github.com/hyperledger/blockchain-explorer). The client is separate from the app (express not serving the UI).
nmarcetic (Mon, 02 Apr 2018 11:13:02 GMT):
I would really appreciate help :) Trying to to put explorer in docker-compose (running backend , UI and postgresql )
rajivgandhi2010 (Mon, 02 Apr 2018 12:43:11 GMT):
https://github.com/hyperledger/blockchain-explorer i have configured and setup the environment by following the above url. I didn't get any errors when I setup. But, When I run "http://localhost:8080/" in browser I got the error
Cannot GET /
rajivgandhi2010 (Mon, 02 Apr 2018 12:43:22 GMT):
can anyone pls help me on this?
rajivgandhi2010 (Mon, 02 Apr 2018 12:43:31 GMT):
Thanks in advance.
nmarcetic (Mon, 02 Apr 2018 12:45:47 GMT):
@rajivgandhi2010 That's because nodejs app are not serving the UI at all.... I manually build the client app
```
cd client
npm install
npm run build
```
And add this in main.js at line 60
```
app.get('/', function (req, res) {
res.sendFile(path.join(__dirname, 'client/build', 'index.html'));
});
```
Now when you open the localhost:8080 UI will be served
nmarcetic (Mon, 02 Apr 2018 12:46:09 GMT):
Even the documentation is not OK :) https://github.com/hyperledger/blockchain-explorer#build-hyperledger-explorer
nmarcetic (Mon, 02 Apr 2018 12:49:46 GMT):
If you see the blank page on UI after loading, open the chrome console and check for errors , for example in my case I see `react-dom.production.min.js:164 TypeError: Cannot read property 'forEach' of undefined`
rajivgandhi2010 (Mon, 02 Apr 2018 13:05:19 GMT):
I'm getting "Error: listen EADDRINUSE :::8080" in log.log file
nmarcetic (Mon, 02 Apr 2018 13:06:34 GMT):

nmarcetic (Mon, 02 Apr 2018 13:09:26 GMT):
Yes, [change config.json](https://github.com/hyperledger/blockchain-explorer/blob/master/config.json#L45) then [change proxy port on client](https://github.com/hyperledger/blockchain-explorer/blob/master/client/package.json#L45) and don't forget to rebuild the client
```
cd client
npm install
npm run build
```

@ayang99 I think we have to start the web server tho (client folder i think) (main.js is the backend it seems)
FlorentinoSainz (Thu, 05 Apr 2018 07:59:13 GMT):
@ayang99 yup, just go to the client folder and run "npm start", there you have your front end :)

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=5rHY34n5rcPPEjTAX) @manish27 whats your error and how's your config file?
FlorentinoSainz (Thu, 05 Apr 2018 15:34:57 GMT):
At the end i managed to pseudo-make-it-work, had to modify some code because I'm using only one peer and some of the graphs don't seem to be ready to handle that
FlorentinoSainz (Thu, 05 Apr 2018 15:35:23 GMT):
(just in case someone is using a network with only one peer)
FlorentinoSainz (Thu, 05 Apr 2018 15:45:35 GMT):
plus if using non-ssl, there's some code which reads the configuration and doesn't work if you dont include tls cert property of the node... (!!)
ayang99 (Thu, 05 Apr 2018 17:31:00 GMT):
@FlorentinoSainz That's super-helpful, thanks! I'll try it out later. What change did you need to make to the code? I am also only running a single peer.
ayang99 (Thu, 05 Apr 2018 19:18:57 GMT):
the GUI is browser-based: http://localhost:3000 usually. When I first started, I followed the steps here: https://github.com/hyperledger/blockchain-explorer#running-hyperledger-explorer and got it working without having to "npm start".
ayang99 (Thu, 05 Apr 2018 19:59:03 GMT):
Also - what did you put for the tls_cert property? I get various errors with both an empty string, and a path to a cert from a different network
ayang99 (Thu, 05 Apr 2018 20:29:52 GMT):
ok - got a quick run-down from a ReactJS guy - running npm start in the client runs the front-end part in development mode. You get useful stack traces and error reporting in the browser. Building the Explorer in "production" mode requires you to do the "npm run build" in /client which will generate the static files that then get statically linked-to by the web-app part (the node main.js in the blockchain-explorer parent directory) - this hides any useful error messages
ayang99 (Thu, 05 Apr 2018 20:30:46 GMT):
so, if you make a change to any of the code under /client, then you will either need to do a "npm start" or "npm run build"

Hi
I found a thing wired. I also detected the same issue with [this one](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=4CNz22FqpFPF8bji5). I could work around the issue that brower is not displaying anything by putting 'tls_cacerts' in config.json even though my fabric 1.1 environment is non-TLS. I just reported about it [here](https://stackoverflow.com/questions/49853848/hyperledger-explorer-is-empty-with-query-error-no-identity-has-been-assigned). Is that reasonable?
howdyeyey (Mon, 23 Apr 2018 02:07:29 GMT):

@nfrunza thanks for the clarification
FlorentinoSainz (Mon, 23 Apr 2018 07:41:09 GMT):
@nekia there's a bug in the code yes, any peer without tls_cacerts gets ignored
FlorentinoSainz (Mon, 23 Apr 2018 07:41:45 GMT):
I removed that check in an if and everything worked (looked like no issues, but idk, I don't know the code)

Hi @MohammadObaid Please use the template provided by AWS, it has all the required Orgs and peers setup with Hyperledger Explorer working out of the box. Please try this and let us know https://aws.amazon.com/blockchain/templates/getting-started/

When creating the IAM role, it requires two privileges 1) AmazonS3FullAccess 2) AmazonEC2ContainerRegistryFullAccess

Hello everyone, I have deployed the newest version of hyperledger-explorer but i have an issue. My network has 4 channels and the app displays them all in the dropdown, though not all dropdown is visible. Nevertheless, when i click on another channel, the dashboard does not seem to refresh the data to the new channel. I still keep the old version before the change of the ui and it works correctly. Is this an aware issue or it justs happens to me?
mengluo668 (Mon, 07 May 2018 01:41:39 GMT):
@vanitas92 you have to bind channels dropdown event to redux action dispatch. The dispatched actions It will load the data of new channel from api and save return data into redux store. As I remember, you can find out the demo of `how to map dispatch to state` in explorer source code

I am doing a hyperledger composer .bna file running a local network
varinder (Mon, 07 May 2018 17:32:56 GMT):
I am running a hyperledger composer network with a modified .bna file and rest server to do the transactions. It's all running fine but struggling to make explorer work with it. I saw @prmdmshra was doing something similar. It seems the config.json requires quite a few changes so thats where I may have issues in.. I will attach below the error I am getting using *tail -f log.log* in blockchain explorer and I will attach my config.json

I'm struggling to get Explorer to work with my Fabric 1.1.0 network. Originally tried installing the master branch of Explorer and running on the existing peer box which had Node version 8.11.1. Following the readme steps I got everything to work just fine, run the startup.sh and the log showed all of the existing blocks being scanned. No apparent errors. But visiting the localhost:8080 results in a quick graphic suggesting that things are loading and then a blank screen. Per the advice I saw above, I tried using the release-3.1 branch but I'm getting the same results. I also changed the nodejs version to 6.9.5 per the readme dependencies section but get the same results. The log file shows no errors despite a blank page coming up. I'm sort of at a loss as to how I troubleshoot further. I'm a little new to this world and don't fully understand how all of these components are stitched together. Can somebody point me in the right direction to discover a little more about why I can't get this to run?

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=WgNpYFbgbXTimfFxZ) @vchinoy My apologies for the port confusion. I originally didn't know how to kill/restart the process once I had launched it and so every time I changed something and went to restart Explorer I was using a new port. Hence making it up to 8086. But I did some googling and figured out how to end the processes on a particular port and hence I am now able to keep running on 8080 even with a restart. So the errors I pasted are valid as I was running Explorer on 8080 at the time.

I have the same problem as @header340 ...
I'm using Ubuntu 16.04, Fabric v1.1.0, Composer v0.19.5
I've got hyperledger-explorer 0.3.0 installed earlier in the week
I've edited the config.json - and I can supply it later but it is a bit long.
when I run the start script data gets written into the postgres database, and when I issue the command `curl http://localhost:8080/api/status/composerchannel` I see this data `{"chaincodeCount":"4","txCount":"31","latestBlock":21,"peerCount":"1"}` so I guess the collection side of things is good.
When I hit port 8080 with the browser I get a nice graphic and a couple of status lines then a blank screen. My console in Chrome shows these errors:

@header340 ok so if you are hitting http://localhost:8080 correctly, the error (Cannot read property 'foreach' in headerview.js) suggests the channel list is empty. And without a channel name, the app cannot fetch any data and hence the white screen. If the API call to get counts works, it cannot be a network connectivity issue, check config.json as for initial setup explorer reads from config file. Also Is your explorer code from release-3.1 branch or release-3.2 branch or master. If your network is fabric version 1.1.0, you need release-3.2. If your fabric network is 1.0, explorer version 0.3.0 from master will work fine for you. If you originally had fabric 1.0 and want to migrate to 1.1.0, fabric provides an upgrade guide and then you can checkout explorer from release-3.2 branch and build. Besides that if you ran npm install in the blockchain-explorer directory and then again in client directory and ran 'npm run build' in client directory before starting up app, it should be good. What happens if instead of using the start script, you run 'node main.js' in the block-chain-explorer directory.
header340 (Thu, 17 May 2018 20:08:10 GMT):
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=bpZPNvkEpA3eDuk8Y) @vchinoy I had been running release-3.1 per someone's comment from a few days ago that I saw when researching my issue. I just switched to release-3.2 and so far I'm seeing the same results. Your comment about the channel list being empty is intriguing, however. The config.json has the correct channel name but I did notice while logging into the PostgreSQL db and looking at the data within the tables, there is data within all the tables I would expect (Transactions, Peers, Chaincodes, Blocks, etc) but the Channel table is empty. The data within the Chaincodes and Peer table show the correct channel name listed. However, I do also notice in the Peer table that the Org an MSPID columns are empty. Not sure if that's relevant or not. I'm having trouble unweaving the architecture of both the main app as well as the web pages to figure out where the channel seems to get lost in translation. Stupid question but it isn't a requirement to create the channel through this app is it? My channel already exists and I'm expecting it to get picked up. I do see where the create channel functions save the channel name into the channel table but I haven't found yet where it saves it there if the channel already exists.

Hi All - a general question: when you develop on Ethereum, you are forced to store the barest minimum of data on the blockchain itself, the actual data gets stored off-chain somewhere like IPFS. This constraint is Ethereum-specific, but does that mean people are storing large payloads in Fabric blocks? Maybe not GB, but on the order of MB?

There is no insertion to the `channel` table. And I think that is a problem why web-interface is not working for me.
BTW I've already reported about this bug and we have jira task https://jira.hyperledger.org/browse/BE-250

I am trying to connect hyperledger-explorer to a hyperledger-composer network, I followed the instructions in the github repo,both build and run : https://github.com/hyperledger/blockchain-explorer. I see no errors in console or log file, but when I navigate to localhost:8080, it tries to load the network and then I see a blank screen. In the web browser console. it says : WebSocket connection to 'ws://localhost:8080/' failed: WebSocket is closed before the connection is established. And then I get type -errors, because the HeaderView.js cannot read channels [probably cannot fetch from server since ws is closed]. This is my config.json file :

I connect explorer to a new hyperledger composer peer node.And it worked like good.In the web browser, It show that generate hundreds blocks.But in the peer of docker, I just find one blockfile in /var/hyperledger/production/ledgersData/chains/chains/composerchannel folder.And the file size grow up for serval hours. I want to know, one blockfile contain one block, or , one blockfile could contain many blocks?

i am using the latest fabric from master branch.
Can anyone tell me, what is the transaction count under the chaincode tab in explorer ?
I implemented a multi peer multi organization network following this tutorial https://hyperledger.github.io/composer/latest/tutorials/deploy-to-fabric-multi-org. When I run the explorer, under organization transactions, OrdererMSP, Org1MSP and Org2MSP are the creators. How do I change the names of these organizations so as to reflect some genuine names rather than Org1MSP and Org2MSP. Same case with the peer names as well. I want some other names than peer0.org.example.com. Will it work if I just change it in the config.json file or do I need to set up the organizations and peers with a particular name beforehand?

@MeghaGupta is your fabric network using tls?
yes
its docker-composer
or How I can cross check it ?
this is defult docker conposer provided by https://github.com/hyperledger/fabric-sdk-java

@MeghaGupta are you sure your tls_cacert is correct, you need this certificate to be from the same fabric network which you've deployed
yes

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=uob9mtKwFYD22icCt) @jeevas I tried explorer and it did work.. when there was config.json present in clone. Now its been removed and replaced by appconfig.json
Could you please help, How to deploy/make it working with appconfig.json
there are no steps involved in readme

@npc0405 @knagware9 The fabric related config has been shifted to `https://github.com/hyperledger/blockchain-explorer/blob/master/app/platform/fabric/config.json`
Now `appconfig.json` is only about host and port
Thanks !!! So I will do config related changes in the same above mentioned file....? @ajmeraharsh
yup!
Thanks a lot :)
@npc0405 @jeevas I will try with this config file ,,,I was getting error means not able to read config file
Yeah same getting "Handshake failed with fatal error SSL_ERROR_SSL: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number."
Any idea on this....am i missing some config?
check ports if correctly mapped
If all correctly mapped then check for grpcs and then change to grpc

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=wp3khH75ZcZ6FCXix) @SeamonJia Do you want to contribute?
@nfrunza Sure. I'd like to contribute.
I noticed that we have to define settings in networkconfig.js for exploring Hyperledger Fabric. I wonder if the Hyperledger Explorer can explore a dynamic network, such as one that has new peers added dynamically?
After running, the synchronous blocks are written to the PG database. Can they be dynamically acquired? Polling index is too slow to keep up with the current block information.
On the other hand, how to increase the speed of writing to database？
@lwrabbit What do you mean by dynamically acquired? I suppose the listener is listening the event and can synchronize in interval.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=LcFj26Qn5Qgr2Z9pF) @lwrabbit
Hi @lwrabbit could you please share yours appconfig.json
I solved that problem，thanks @MeghaGupta
@SeamonJia Query the information in current time when clicking the details of the block
Hi I was asking for reference .. I have set the host and port but still not able to connect ..:D @lwrabbit
@SeamonJia Instead of writing the database after the query。
I was using config.json which give kind of template but appconfig.json is different. @lwrabbit please help
@lwrabbit When clicking the details of the block, I suppose the Explorer will call API to retrieve information stored in the PG db.
I did not update the appconfig.json. @MeghaGupta ,the config.json path is app/platform/fabric/config.json,you can update it there.
@lwrabbit Did you mean it should reach out to Fabric network to get the latest information?
@SeamonJia yes
ok thanks @lwrabbit
@lwrabbit Got it. But won't it affect the performance of the Fabric network if the block you request never changed?
Does query performance have a great impact on writing? In my application scenario, I want to write data to the Fabric network in real time. @SeamonJia
Hi @lwrabbit could you please help me with "configtxgenToolPath": "fabric-path/fabric-samples/bin",
@SeamonJia I tried to drop the database and restart explorer. The PG database began to read and write from the first block, but if reading block could not keep up with the speed of the block generation,then?
I am using fabric java sdk
@MeghaGupta the path is your real path of storing the binary file
so I can give any path ?
yes
again thanks a lot
any where you can store :wink:
@lwrabbit any idea on this error : blockchain-explorer/main.js:46
async function startExplorer() {
^^^^^^^^
SyntaxError: Unexpected token function

@lwrabbit Sorry, I'm still on my woking time in office. You do have a good point. But in my opinion, there's little chance that PG reading block could not keep up with the speed of the block generation in Fabric.
Even it falls behind, the information delays in showing the latest is tolerable, right?
@lwrabbit BTW, I noticed that we have to define settings in networkconfig.js for exploring Hyperledger Fabric. I wonder if the Hyperledger Explorer can explore a dynamic network, such as one that has new peers added dynamically?
@MeghaGupta The node version is not 8.9.x
I suggest you use 8.9.4. You can install nvm for switching between different node version.

Great! It seems to be working fine in my composer environment ( fabric 1.1.0 ). I have one thing. My environment consists of 5 organizations. Peers Health list is working fine ( I can see peers on each organizaition ) but the number of nodes is still 1 on Dashboard screen and I can see only 1 peer (peer0.org1.example.com) on Network screen. Does anyone know how it is expected to work ?

Hello, Explorer team, I saw your project and came up with a couple of questions. First of all, I have seen a message in your mailing list about making your explorer compatible with Sawtooth.

@vanitas92 I met the same issue before. You can try to modify the updatepg.sql file your self and make these columns longer and then re-setup the database
```
ALTER TABLE Transaction ADD COLUMN validation_code character varying(50) DEFAULT NULL,
ADD COLUMN envelope_signature character varying(2000) DEFAULT NULL,
ADD COLUMN payload_extension character varying(2000) DEFAULT NULL,
ADD COLUMN creator_id_bytes character varying(2000) DEFAULT NULL,
ADD COLUMN creator_nonce character varying(2000) DEFAULT NULL,
```
I made all the columns with the length 2000
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=ZHAHAYpnB4z7pNH7w) @RealDeanZhao Thank you. I though the same and i was trying to figure out which column was by checking the logs of postgresql
I was thinking the reason of limiting the character types in these columns. A quick consult in the following official documentation link: [https://www.postgresql.org/docs/9.0/static/datatype-character.html](https://www.postgresql.org/docs/9.0/static/datatype-character.html) says that if you do not specify the varying(n) then the database accepts strings of any size. Moreover, there is no performance issue.

Hi All, is there any API to get all peers of the channel?? the explorer always shows the default peer of the default org..
```
async setChannels() {
var client = this.getClientForOrg(configuration.getDefaultOrg());
var proxy = this.getDefaultProxy();
var channelInfo = await proxy.queryChannels();
channelInfo.channels.forEach(chan => {
var channelName = chan.channel_id;
let channel = client.newChannel(channelName);
channel.addPeer(this.getDefaultPeer()); // this line should add the list of the channel peers, not the default peer
this.setupOrderers(client,channel);
var channel_event_hub = channel.newChannelEventHub(this.getDefaultPeer());
this.channels[channelName] = new FabricChannel(
channelName,
channel,
channel_event_hub
);
});

@RealDeanZhao There is no point adding peers that we read off of config file. So the idea was to wait until network discovery is available. Fabric 1.2 offers the functionality so we will be able to fetch all peers for the given channel. We are close to providing a fabric 1.2 compatible version of explorer, stay tuned for updates on that.

Hi I added blockchain explorer to my hyperledger composer project, It works almost fine but I met 2 problems:
1. the peer name does not show up
2. the web client does not auto refresh , when new block is made the number near notice bell (left top) is changed automatically but other part of web does not change until refresh all page manually

GUYS!!! Whats the best starting point for implementing Hyperledger Explorer? The Github page is...not very helpful...any assistance would be greatly appreciated!!
Hi all, in DESPERATE need of some help...Ive set up the Hyperledger Explorer as per the GitHub page...however when I navigate to localhost:8080 - I get a nothing!!! PLEASE HELP
GUYS!!! SOME ONE IN THIS ROOM HAS THE ANSWER!!!

Hi all just wanted to share a solution to a problem I was having....I followed the Hyperledger Tutorial here: https://github.com/hyperledger/blockchain-explorer
I tried for many hours to get it working, but every time I would navigate to local host I would simply get a blank screen. To find out what the problem was I went to the logs folder and realised that the config.json file did not accurately reflect my directory structure....basically the file path was wrong! I fixed it and it worked. The reason Im sharing this is because Im sure there are many people who are beginners and perhaps need the help..

Hi! I‘m a newcomer to blockchain-explorer, and I have built the explorer following the tutorial. Now I want to display something new about blocks or transaction ( just like some data generated in my chaincode ) but I can't find how the api request gets the data response ( a path or databases ). Is there anybody can explain how it works for me? thanks a lot~~

@nfrunza What should the correct paths be?

Hey there,
I am trying to bring this up for a running Hyperledger Composer (based on Fabric) blockchain, but I am unsure whether I am doing the correct steps to rebuild explorer after I changed app/platform/fabric/config.json
Currently I am running these commands after I updated config.json:
`cd ~/blockchain-explorer
npm install
cd app/test
npm install
cd ~/blockchain-explorer/client
npm install
npm run build`
And afterwards I restart explorer with
`./stop.sh && ./start.sh`
And finally I get the following two errors:

Hi all..
I did a multi-host environment setup with hyperledger fabric which contains 3 VMs. VM1 - Orderer and Cli, VM2 - 2 CA, 2 Org peers and 2 Couch Dbs and similarly in another
Now i installed hyperledger explorer in VM1 and did json config something like this
"name": "OrgXMSP",
"mspid": "OrgXMSP",
"peer0.orgx.acmesystems.com": {
"requests": "grpcs://peer1-orgx:7051",
"events": "grpcs://peer1-orgx:7053",
"server-hostname": "peer0.orgx.acmesystems.com",
"tls_cacerts": "/home/user/blockchain-network-1.2/crypto-config/peerOrganizations/orgx.acmesystems.com/peers/peer0.orgx.acmesystems.com/tls/ca.crt"
},
"requests": "grpcs://peer1-orgx:7051",
"events": "grpcs://peer1-orgx:7053",
these two tried with IPs as well but nothing works
My fabric version is 1.2

Hi , I have created blockchain explorer using composer framework. It is opening fine but transaction tab is not working

I have resolved the error
it was the "configtxgenToolPath": should point the correct path of your configtxgen binary file

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=dbax4eRRPjyQNaQfR) @nfrunza @nfrunza So what should be our approach to use explorer when we have huge volume of data. Is explorer not meant to handle huge volume of data. Please suggest us. we want to use explorer keeping in view the tons of data we may add in future.
I trying to call Fetch API inside chaincode like so:
```
async function getid() {
return await fetch(PROXY_API_ADDRESS, {
method: 'GET'
});
}
```
And I get error:
```
Response from attempted peer comms was an error: Error: 2 UNKNOWN: error executing chaincode: transaction returned with failure: Error: ReferenceError: fetch is not defined
```
Why? I can't do any request inside chaincode?

Drive C is shared, docker works fine from git bash, and _config.json_ file exists in the source path, I am missing something?
OK got it
This is because of Git Bash appending ";C" when converting Windows paths

alone
@nfrunza -- I had few queries with regards to the items being populated in the charts.
Nodes --> What exactly is meant by nodes over here, I have 3 VMs with total of 4 orgs and each orgs with 2 peers and 1 user (But node count is 1 for me always)
Peer status -> This area all the peers are being listed with status as "Down". Why is it so is this expected ?

* Removed 'tls_cacerts' entry of each peer ( It's mandatory even if you disabled TLS )
* Specified wrong protocl for peer URL ( I should specify grpcs, not grpc )

@RockyRacer if see troubleshoot.md file it clearly mentions this error is due to Fabric network being not identified by the explorer code. Hence if you check the configuration.js you would be able to see how it actually retrieves values from the config.json
I rectified issues which i faced by checking code and making modifications accordingly

@nfrunza I finally got it to work by :
- removing network creation [deploy_explorer.sh]
- replacing network name with the existing one running my fabric installation [deploy_explorer.sh]
- removing `--ip` parameters when running db and explorer containers [deploy_explorer.sh]
So all containers run in the same network, then I had to :
- replace `db_ip` with the one got from the db container IP in the existing network (`docker network inspect mynetwork`) [deploy_explorer.sh]
- replacing 127.0.0.1 by service name [config.json]

Thank you for your support :thumbup_tone2:
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=qcMFtSn8d5AZmQT3W) @RockyRacer Congrats. I am still trying to work this out and am a bit lost in what you did. Where is this deploy_explorer.sh? Are you running a custom fabric-network or one of the sample ones?
Ok, strike the question about the custom fabric :-) Read your above messages again
Yeah I had a previous running Fabric network, just wanted to connect Explorer on it.
I still don't understand why the default deploy_explorer.sh script for running Explorer with Docker create its own network, because of that it cannot speak with the Fabric network.
Hm, ok, anyway. I am currently debugging the js and there is stuff in there that is never mentioned in any documentation, but I am getting somewhere. For example the info that the JSON-key for an organisation should start with "org" is never mentioned and just happens to be the case in the samples... Why? As well as the info that the peers must seemingly be numbered (starting with "peer1", which is assumed to be the default peer).
+1 it tricked me too, and should be mentioned somewhere
Yeah, so for me it got resolved. For anyone with similar weird errors: Maybe try to understand what the files app/platform/fabric/{Platform,Configuration].js do. I personally spiked them with console.logs and the logs showed up in logs/console/console.log-[current date]

Clipboard - August 8, 2018 3:01 PM
What is this node in this section and why is it always 1 ? I am having 3 VMs with 4 Orgs
Clipboard - August 8, 2018 3:02 PM
Why always peer status is as down ?
Yeah, I am also confused by some stuff in the UI, but for me it's more of a proof-of-concept, so i generally don't worry about it to much. My assumption concerning the 1 peer and also in the network tab is only 1 peer listed is that in the Configuration.js (mentioned above) there is some handling of "defaultOrg" and a "defaultPeer" and I assume that the peer is just the default organisation's default peer. At least in my network that is the case.
However all my peers's status is "running". So maybe you should check your peers. Are all the ports open (7051-7054 usually)?

You also see only one peer in network tab ?
Looking at the DashboardView.js file "Nodes" represent the number of peers
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=oZKacGeYzLWLYvCTF) @rajanashutosh I updated the org and peer keys. In addition, I am using grpc.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=wgDnhB2ZyEMrAxJmb) @RockyRacer Yes, the one I'd call the default organisation's default peer (first peer of first organisation as written in the config.json)

Do you also have hundreds of warning from your peer when Explorer is running ?
`hyperledger_peer0.org1.example.com | 2018-08-08 13:07:39.840 UTC [server] validateStructure -> WARN 4e6 Request from 172.20.0.13:51660 is badly formed: +Envelope must have a Header`
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=LepgwecKD27o55f5s) @nfrunza For me it works as follows: Two Peers and one Orderer all running on different VMs. Explorer is running natively on the Orderer, while Fabric runs inside containers. The connection is done via the config.json (for the peers the endpoints are specified via grpcs://[hostname]:[port] and for the port the hostname is replaced by the ip 127.0.0.1).
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=KX4o9GyxG4YH3F4aM) @nfrunza No, these are correct. In the network tab there is only one peer for me
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=Hnn27vh3AMTJ3FQLz) @RockyRacer I don't think so, but some stuff happened on the chain and I do not record the logs, so there might be at the beginning. Definitely not continous
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=fW4Pf59YTMFSYJDDD) @iDix thanks for the reply, good to know
@nfrunza However can you tell me whether the different peers should be there? And also another further issue: In the transactions tab the creator is always the MSP and not the peer. And it is also always the same MSP (I guess because its the channel MSP), but that seems like it is not how it's supposed to work?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=6m7JowadcFTidzDQd) @iDix "However can you tell me whether the different peers should be there?" are you referring to the Dashboard peers?

@bh4rtp - My docker swarm setup is running properly with all data replications across VMs properly. Even we have our own custom API which is able to place transactions which gets replication across VMS and orgs.

no i mean the fabric-ca-server container

i have put it in the crypto directory

same thing again

@Adam_Hardie I revised the config.json file with no-TLS ,and it works now
Although I really want to use TLS :joy:
Maybe it's because you did't have a peer with TLS
@Adam_Hardie
But I got another problem,in the peer container logs it says:
Clipboard - August 17, 2018 11:53 AM
and in the explorer logs/app/console.log ,it says:
Clipboard - August 17, 2018 11:54 AM
Last, my web shows the peer parts:
Clipboard - August 17, 2018 11:55 AM

I already have a fabric network running with 2 nodes and a machine running composer that can deploy bna on those nodes. Explorer can be installed on a different machine, I don't need fabric to installed on the machine to have explorer running, correct ?

But just a last one, so to have Hyperledger seeing my network I have to fill-in this config .json file manually so if a new channel is created later it means that the web interface will not be updated automatically without the modification of the json file, correct ?

Hi, can HL explorer be expressed as a library that can be integrated into a custom built UI. Or are the facilities exposed by Fabric 1.2 enough for block exploring.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=Jkn9fxNhxWMucPQhM) @WCamaly Your fabric network is running on another server? And is the network behind the proxy? Normally you would need to copy the the certs into some folder in the same machine explorer would run and configure config.json to the new folder you copied the certs
yes, the Fabric network if it runs on another server. Is there a way to get it from frabric-ca?

i have 5 channels and configure 5 clients. block-explorer-3.6 is used.
Hello, I have a infrastructure including 2 nodes, both of them are running. On th Hyperledger Explorer, one of them appear as "down" ... can this mean that no chaincode are deployed on it ? or does it really mean unreachabl ? thanks

I have setup a Docker version where you simply have to 1) modify the network name in the compose file 2) adapt the _config.json_ file 3) replace _crypto-config_ with your crypto materials

I am facing some other issue. Now I am running explorer with fabric 1.1
what are the isues
and I am not able to see private channels created from org2 in dropdown
okk
I think somewhere it is hardcoded in the code that it only takes channels created from org1
@sureshtedla any idea...?
No Idea
I created private channels from org1 and org2 seperately. I am able to see channel created from org1 but not the channel created from org2
so these private channels are just joined by their creator org peers

@nfrunza I modified the script to bring up the sample network to start the new network. I should take down the network purge the cryptos, then try again? I think I made some progress, as I now get the loading screen to appear for the new network, however it seems to hang on that screen

yes i can, statements like "SELECT * FROM peer" or "SELECT * FROM blocks" returns data
@nfrunza yes i can, statements like "SELECT * FROM peer" or "SELECT * FROM blocks" returns data, yet explorer hangs on the loading screen

@nfrunza ok I will and will update you after. Additionally, after a period of time explorer loads but is incomplete and shows 0 blocks transactions nodes and chain-codes on the dashboard, which is obviously incorrect. Additionally, upon using api to create a new block it shows up in the database, leading me to believe that it is almost working since the database can see the changes.
@nfrunza after restarting explorer, it still seems to be hanging on the load screen
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=iKHLKDKZbBtsfqSbc) @blakem Please rerun DB setup
@nfrunza I removed the database, then recreated it using the ./creatdb.sh to no avail. I will keep trying though. Thanks

On a new image of Ubuntu 16.04 i was able to bring up my network, set up the database, and am able to see new blocks in the database for explorer. However, for some reason, the page fails to load past the loading screen. Could this be related to the error in the step "npm test -- -u --coverage" where it errors out regarding Landingpage.js?
I finally figured out the issue so I thought I would share in case anyone else is having similar issues. My issue was that I could see transactions occurring in the database for explorer, however, upon trying to go to localhost:8080, it would stay on the loading page indefinitely. The issue ended up being that the channel name that I thought was correct in the config file was incorrect. Thanks again @nfrunza and anyone else that helped me with this issue and other troubleshooting areas.

For deploying explorer in docker, when the script tries to create the user hppoc with password as password using the set variables, it reverts back to :user and :passwd respectively, causing it to fail with a syntax error.

Experiencing same issue as @abityildiz - after trying to upgrade explorer from 0.3.5 to 0.3.6 - looking at code seems that the format of the config.json used to describe your network has completely changed (i.e. not the same as example shown in https://github.com/hyperledger/blockchain-explorer/tree/master/examples/net1) - am going to update to match format here https://github.com/hyperledger/blockchain-explorer/blob/master/app/platform/fabric/config.json) and see if that helps
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=nMWWWwjCjhkRfNBv9) @BarryMcLaughlin this was done to support new futures of the fabric 1.2, discovery etc
@nfrunza, ok that makes sense...trying to figure out how my new config should look for my network...the "clients" section doesn't seem to have any equivalent in the previous config.json format. Any guidance on what is this section describing?

@vanitas92 Short answer...it took a while ;) Longer answer, we were moving from a 0.35 fabric 1.1 setup...and the key gotcha for me was that the config.json structure completely changed...so my advice is to go through that with a fine tooth comb and make sure all the mspids, keys, certs, urls, etc are exactly correct for YOUR network. No point in posting mine because its for out fabric network which is not standard. Use https://github.com/hyperledger/blockchain-explorer/blob/master/app/platform/fabric/config.json as a starting point...this is the correct format. As for how we achieved connection over https...we are running our network on kubenetes and used a TLS ingress. However, sounds to me like your issue is something not matching your network within the config.json - but I'm not an expert in this!

Is it necessary to add details of all peer information in config.json?
In my HLF network currently there are 3 ORG but those ORG are on remote instance and Hyperledger explorer is setup only on ORG1 only so can it be possible give only ORG1 and able see complete network information once explorer is running.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=jB3KSZqkKYEaiFhrr) @BarryMcLaughlin Thanks. I had a similar starting point and no problem until 3.6 and the restructure of config.json is a headache now. I still do not understand what is the meaning of the "clients" section of the json. Im using a completely customized fabric network running in kuberntes too and maybe with your help could get on with this! Thank you very much.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=guFA4nM8b5Bh6iFLo) @vanitas92 I'm also unclear on the "clients" section so if anyone on here has definitive answer please jump in. My guess is it is related to the NodeSDK client config see here :https://fabric-sdk-node.github.io/tutorial-network-config.html. The error you are seeing comes from here: https://github.com/hyperledger/blockchain-explorer/blob/master/app/platform/fabric/FabricClient.js line 116. I also had this error at one point. Reading the code, the first thing it does with fabric client after initialization is call queryChannels and if that returns empty...you get this error. So, either there are no channels on your network or, more likely, the config is wrong somehow and its not able to connect. I would suggest this...take the url to the peer you are connecting to (the one matching organization in the clients section) then remote on to your explorer pod and try a cmd like this: nc -zv {{your_hostname_or_ip_from_url_property}} {{port_from_url}} If this doesn't return open then you have some sort of network issue or your config is wrong. Other things to check that the certs and keys in your config.json are actually there. Sorry can't be of more help but I'm no expert...just hacking my way.

Hi, older versions of blockchain explorer used to update 'almost' realtime. blockchain-explorer-0.3.7 in explorerconfig.json there is a variable blocksSyncTime that is set to 3 minutes by default (sync=local). Also the web page it seems that it needs to be manually refreshed in order to show updates on the fabric. I tried to change the 3 to 0.2 and it just did not work.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=rAWX69hXymsMAA8tX) @joaquimpedrooliveira v0.3.5
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=rAWX69hXymsMAA8tX) @joaquimpedrooliveira v0.3.5.1
I'm attempting to set up Hyperledger Explorer, but my client connection fails somewhere around the line 492 of FabricClient.js, near this code:
```
async getPeerStatus(peer) {
let channel = this.getDefaultChannel();
let adminpeer = this.adminpeers.get(peer.requests);
let status = {};
```
I end up with this.adminpeers being an empty map, so getting the peer.request returns another empty map. It's not entirely clear (given lack of comments in code) how the adminpeer is populated and what function it serves.
Could one of the devs or someone else who suceeded in running Blockchain Explorer 0.3.7 on Fabric 1.2 advise on this?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=CSdgC59kWN44tvPJ8) @alexvicegrab do you use fabric samples, or custom network, and are you using fabric-ca?
s
@nfrunza when I run 0.3.7 through docker and leave it up and running for some hours with HLF 1.2 on the application console I get messages: ```
```
@nfrunza thanks for your reply!!!
When I run 0.3.7 through docker and leave it up and running for some hours with HLF 1.2 on the application console I get messages:
```

on the peer logs I see messages like

```
So which is the most stable version of blockchain explorer, what is the preferred backend 1.1 or 1.2, is it better to run it on docker or natively and is there a version that supports autorefresh of the UI (like it used to)?

can you try with basic network? please. Thanks
@nfrunza thanks, it was config error
@nfrunza explorer support fabric 1.3.0 yet or when will it be availbale?
did anybody tried with basic network??

hi @nfruza , I'v stacked in npm test in v3.8. I changed the password of postgres to postgres which matchs postgrespgtest.js connection property, but still get the following error:

Requests from many developers to be able to run HLExplorer with fabric-ca server.
1) Use fabric-ca client and admin credentials to login to fabric-ca server.
2) Enroll HLExplorer user to fabric-ca, and store the generated user credentials in a temp directory, can be under explorer
3) Verify if user exists on the CA, if they do not, register them.
4) Verify if user exists credentials (key/cert pair) exist before enrolling, and that credentials are valid, otherwise re-enroll the HLExplorer user.
5) Minimize or avoid using CDM tools for generating credentials or enroll HLExplorer user, we want as less as possible use of command tools.
Balance transfer sample has a fabric-ca server, https://github.com/hyperledger/fabric-samples/tree/master/balance-transfer#sample-rest-apis-requests , and can be used top test explorer
Some suggestions how to achieve this :
Suppose you launch root ca (localhost:7054) and intermediate ca (localhost:8054) on localhost.
Firstly, you should register identity with hf.IntermediateCA=true attribute by root ca. For example:
fabric-ca-client register --id.name ica --id.attrs '"hf.Registrar.Roles=user,peer",hf.Revoker=true,hf.IntermediateCA=true' --id.secret icapw
Secondly, open intermediate ca home directory and initialize the intermediate ca:
fabric-ca-server init -b icaadmin:icaadminpw -u http://ica:icapw@localhost:7054
Change port of intermediate ca (8054) and some other settings of intermediate ca in fabric-ca-server-config.yaml file.
After that, you can start intermediate ca:
fabric-ca-server start
```

@jeevas Thanks for your response. In docker, the default work_dir is "/opt", does the doc mean "mkdir -p /opt/explorer/examples/dockerConfig"?

@BlockchainCoE I think it's good choice to use docker-compose to deploy BE, can you provide a sample of docker-compose to run BE?

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=ZWauaK8qAd8cTNXds) @MuhammedHafil you can Setup your basic network using Build your network tutorial from Fabric. Once you setup the network, please modify the values in /blockchain-explorer/app/platform/fabric/config.json accordingly
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=FpwGrM8f5aKazMdsv) @qubing we are creating folder with in explorer application itself."mkdir -p ./examples/dockerConfig" - it will create blockchain-explorer/examples/dockerConfig

fabric v 1.2 ,composer v .20 and explorer v is 3.8 and also tried with 3.7,3.6 also can you please help me out with this issue
I get this error when I start explorer. I've tried changing channel to "composerchannel" and other examples but I'm confused as to what my channel actually is right now and wich config files to modify to get it working. Fabric and composer-playground seems to be running fine.
When I insert "mychannel" in config.json it connects according to app.log
Output of console log:
```postgres://hppoc:password@127.0.0.1:5432/fabricexplorer
<<<<<<<<<<<<<<<<<<<<<<<<<< Explorer Error >>>>>>>>>>>>>>>>>>>>>
Error : [ 'Default defined channel %s is not found for the client %s peer',
'mychannel',
'client-1' ]
Received kill signal, shutting down gracefully
```
Otherwise if I insert "composerchannel", app.log says
`[ERROR] FabricUtils - Default channel [composerchannel] is not defined in configuration`
and console log:
```
postgres://hppoc:password@127.0.0.1:5432/fabricexplorer

@jeevas I got explorer running now, but I get this error message during the sync process (I believe)
` [DEBUG] FabricClient - Admin peer Not found for grpc://127.0.0.1:7051 `
Any ideas as to what might cause that one?
Wow. I got it running. (pats myself on my back) :sunglasses:
Solution: https://jira.hyperledger.org/projects/BE/issues/BE-471?filter=allissues
@jeevas I solved the channel problem by switching "mychannel" with "composerchannel" in some of the config files, it wasn't consistent all over. I didn't notice it due to formatting/lack of understanding of file buildup
The readme states 'nodejs 8.11.x (Note that v9.x is not yet supported)' . But node is already on v10.12.0. Is that line correct?

@Ferrymania it is caused that block-explorer does not support fabric-ca.

@nfruza thanks for your reply, dose explore have i8n function
can i use tag version?
@Ferrymania can you share your config.json
@nfruza could u tell me how to disable wagger-UI ?api-docs/#/
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=hirzhgC4Fa9DHXF9f) @davidhu if you want disable the swagger-UI you can commend this line(this.app.use(

swaggerUi.setup(swaggerDocument)
); ) in explorer.js (blockchain-explorer/app/Explorer.js)
@jeevas yeah, that's a good idea, thank you

can someone help me? I'm able to run older version of explorer (older than 3). But I want to update to the new one due to stability problems
For Info, the hyperledger fabric network is running well. And the credentials I use for the explorer are the one created by cryptogen using the fabric-tools docker image.
I have noticed the following error message when I execute "peer node status"```

I found that when I try e2e-cli netowrk which contains 2 CA 4 peer order and kafka ,the explorer would work ,but use my network same config ,the explorer would fail to start,I guess the difference between them is that mine is use node-sdk to register user and create channel . ~~:joy:

Hi @Karthik1337. It looks like explorer app couldn't ping nodes via localhost. You may login into the container and try to reach peers from it.
Has joined the channel.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=dYHyg6tazX9AHgjEa) @Karthik1337 I'm having the same issue right now!
Really don't know what's the cause
Used the command `./deploy_docker.sh dockerConfig net_byfn` to test explorer with byfn example, and even if the explorer container is connected with the net, it gives me the same error

- CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.org1.example.com:7051
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=7unHr6fkJKLyNHX9b) @fksaito Will check in our environment and get back to you
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=AK9NjRpS6KgTt4k7M) @Randyshu2018 you can use release 3.5 branch and support fabric 1.1 (https://github.com/hyperledger/blockchain-explorer/tree/release-3.5) but peers data load from config.json and not from Fabric.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=fSiJBPDa3tW78jjgp) @Randyshu2018 which fabric version are you using?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=Skrqcjpgjkw6vbYy4) @Ferrymania No I didn't. I'm working on another thing right now, I think I will try to solve problems later sorry
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=p3zAtAZyswsMPFe3q) @jeevas fabric1.1 & blockchain-explorer version is release-3.5
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=qWQ4C5QkJ4F3e3gvt) @Randyshu2018 I try fabric 1.2 and BE 3.7 it also show only 1 peer in the dashboard:joy:
:joy: the master branch will be fine...it use service discovery to do synchronize.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=9YxEwk49Aph4L7hKa) @Ferrymania Please use master branch
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=e2c8iYKPEqjLFBigD) @jeevas :grimacing: Thanks I will try
@Karthik1337 it seems that you have a typo in the config: `OrdererMSP.adminPrivateKey.path` has an error. It should be `/ordererOrganizations/engineering.test.com/`, not `/ordererOrganizations.test.com/`
@GiovanniNapoli could you please provide your `config.json` and project structure?

I had to switch from grpcs from grpc because it didn't work...An error occured ever before registering users using crypto material. Using grpc, this phase passes and then comes to the error i said before

8. tar -xvf fabric-dev-servers.tar.gz
If based on your use case you can export Fabric version in below example
Fabric 1.1
cd ~/fabric-tools
export FABRIC_VERSION=hlfv11
./downloadFabric.sh
Fabric 1.2
cd ~/fabric-tools
export FABRIC_VERSION=hlfv12
./downloadFabric.sh

cd ~/fabric-tools
export FABRIC_VERSION=hlfv11
./startFabric.sh
./createPeerAdminCard.sh
Fabric 1.2
cd ~/fabric-tools
export FABRIC_VERSION=hlfv12
./startFabric.sh
./createPeerAdminCard.sh
Hyperledger Explorer Configuration :
Before modify the config.json please check docker is up or not – use this command “docker ps”
If you are using latest version (Master branch )of Blockchain Chain explorer then you should use Composer Fabric 1.2
U need to change below datas . I am giving composer datas
tlsEnable - false
channel – composerchannel
3. adminPrivateKey , signedCert, tlsCAcerts – path - fabric-tools/fabric-scripts/hlfv12/composer/crypto-config/../..
peers – url and eventurl
Orderers – url
If you are using Fabric 1.1 please follow url to configure in config.json

@jeevas - let me know what am I doing wrong here...
The explorer connects to the network - shows nodes,channel details , but no block or transaction details ( rason being the javascript error thrown for unknown function ). Pls help

Well i guess it may take a while, but any help appreciated :) quite a tight situation where I need to look at some Fabric analytics asap. I'll be around whenever.
Has joined the channel.
I'm familiar with Sawtooth not Fabric, but the best way to do analytics is to either query the blockchain directly, or sync it into a database and run queries there.
In fact, that's true for analytics of all blockchains.
A minor exception for analysis of ethereum smart contracts, in as much as you only get bytecode on-chain but many people upload source code to etherscan.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=mXkNni4c7KkQwn6aF) @VikasJakhar did you check block details available in Explorer DB?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=JhoyRHxm9D4z3E4cf) @nemo 8 your config.json file is not validated . Let me know which version of Blockchain explorer are you using.
hmmm, It's just the live one @ https://github.com/hyperledger/blockchain-explorer I think @jeevas
config.json.txt

any plans to make the explorer compatible with fabric v1.3? https://github.com/hyperledger/blockchain-explorer/blob/master/release_notes/v0.3.7.md

Hello good people. I have tested hyperledger explorer release-3.4, with the hyperledger fabric 1.1.0. This worked perfectly with the first-network. But when i connect the same explorer with another fabric network from sample source I found online, it fails to display on the screen.

But when i connect the same explorer with another fabric network from sample source I found online, it fails to display on the screen. Is there anything i need to change in the client of hyperledger explorer. The fabric network is okay, and I can see that block are inserted in the database, but its not displayed on screen. (i changed my config.js , pgservices.js accordingly). I don't know what I am missing. Any ideas. Has anyone tested hyperledger explorer with any other network other than fabric sample's first-network and it worked?

@nfrunza Okay but still it was not running, is there any problem with the config file?
@hkrichen You have to change your config file as [shown](https://github.com/hyperledger/blockchain-explorer/blob/master/CONFIG-COMPOSER-HLEXPLORER.md)
@hkrichen You have to change your config file as [shown](https://github.com/hyperledger/blockchain-explorer/blob/master/CONFIG-COMPOSER-HLEXPLORER.md) and mentioned in the readme
PS: Still trying to do that myself
XD
@Paradox-AT this configuration is for old versions of explorer
Has joined the channel.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=PkoNMuPZxn5C2Exgr) @hkrichen please describe your fabric, is is a sample, or custom? i would suggest first using fabric-sample/first-network then you can work on yours to understand
@nfrunza Hello, I'm using this fabric https://github.com/hyperledger/composer-tools/tree/master/packages/fabric-dev-servers
@nfrunza Hello, I'm using this fabric https://github.com/hyperledger/composer-tools/tree/master/packages/fabric-dev-servers V1.2
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=2oZMokFKpCmyW3bFd) @hkrichen try using explorer v3.4
Has joined the channel.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=v6f3n5oxJ9jQTEJzP) @nfrunza Yes, I'm using a custom fabric network. It worked on multi-host environment(5 different PC).

Hi Experts, Would like to seek your assistance/guidance to an issue that we are currently encountering while integrating Hyperledger-explorer version 0.3.7 in Hyperledger Fabric 1.2.
Issue Details
- In 'app/platform/fabric/FabricClient.js' file there is a piece of code in the 'initializeChannelFromDiscover' method - this.client_config.peers[host]
- 'this.client_config.peers' is an array (array details given below) with peer names as the keys.
- But the in the above line the value of 'host' variable is coming as ip/hostname of the server where the peers are running.
============================================================================================
The array value of "this.client_config.peers" -----
{ 'peer0.org1.example.com':
{ tlsCACerts:
{ path: '/home/ubuntu/.../tls/ca.crt' },
url: 'grpcs://ec2-52-15-xxx-xxx.us-east-2.compute.amazonaws.com:7051',
eventUrl: 'grpcs://ec2-52-15-xxx-xxx.us-east-2.compute.amazonaws.com:7053',
grpcOptions: { 'ssl-target-name-override': 'peer0.org1.example.com' } },
'peer0.org2.example.com':
{ tlsCACerts:
{ path: '/home/ubuntu/.../tls/ca.crt' },
url: 'grpcs://ec2-18-224-xxx-xxx.us-east-2.compute.amazonaws.com:7051',
eventUrl: 'grpcs://ec2-18-224-xxx-xxx.us-east-2.compute.amazonaws.com:7053',
grpcOptions: { 'ssl-target-name-override': 'peer0.org2.example.com' } } }
============================================================================================
It seems there may be some issue with FabricClient.js file or some other config related file. It might be a trivial issue , but we are spending time to get it resolved.
If you have any quick suggestion , looking at the above details , kindly do let me know
Thanks, Chandrika

Hello, I'm having some trouble starting version 3.7. I am using fabric version 1.2.1 and i got it "working" with explorer version 3.5 (it boots and shows transactions). When i try to use version 3.7 i get an error when i start the nodejs server. I think the problem is in my config.json file but when i compare the one from 3.5 to 3.7 i see no reason why this wouldn't work. Is there someone i could send my 2 network.json to that can take a look?

Hi! I've been learning about explorer for some weeks now. I tested with a couple of samples I found online. Now I wanted to add it to my HL Composer network, custom BNA but the network itself is the sample one with one peer and one orderer. I am getting this error and not sure why... I tried a lot of stuff:
E1106 11:59:21.357924814 6 ssl_transport_security.cc:989] Handshake failed with fatal error SSL_ERROR_SSL: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number.
I do set the TLS certs correctly. If I do practically the same with the first-network sample I can get it to work
@emiliomarin You might try with setting tlsEnabled to false, I did that and got it to work
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=p7h2rzhiywduhJ7kt) @emiliomarin use explorer tag v0.3.5

@titoe218 Are you sure that you're connecting to the right endpoints? Furthermore, make sure that there is a long enough delay between starting the peers and trying to connect to them. I've run into issues in the past with that.
@tballast How do you configure peer url, event url? This is mine
`"url": "grpcs://localhost:7051",
"eventUrl": "grpcs://localhost:7053",
"grpcOptions": {
"ssl-target-name-override": "peer0.org1.example.com`
Gotcha, do you have TLS properly enabled? If not, then you're going to want to change the grpcs to grpc. Furthermore, look in your docker-compose.yml file to find the endpoints. You should have something that resembles this in some way:
```
peer0.org1.example.com:
container_name: peer0.org1.example.com
extends:
file: peer-base/peer-base.yaml
service: peer-base
environment:
- CORE_PEER_ID=peer0.org1.example.com
- CORE_PEER_ADDRESS=peer0.org1.example.com:7051
- CORE_PEER_GOSSIP_EXTERNALENDPOINT=peer0.org1.example.com:7051
# - CORE_PEER_GOSSIP_ORGLEADER=true
- CORE_PEER_LOCALMSPID=Org1MSP
volumes:
- /var/run/:/host/var/run/
- ./e2e-2Orgs/${CONFIG_FOLDER}/crypto-config/peerOrganizations/org1.example.com/peers/peer0.org1.example.com/:/etc/hyperledger/msp/peer:ro
ports:
- 7051:7051
- 7053:7053
depends_on:
- orderer.example.com
```
You can see that the address is peer0.org1.example.com:7051, so your URL should be ok, as long as your ports are correct.
@tballast Thanks but I try many ways as you suggested but it still not working with same error :( any ideas?
@titoe218 Sorry, not at the moment. I will probably be trying to get this working for myself soon though, and if I run into the issue and solve it I'll be sure to let you know.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=z9ZmJ8nnoNhQ8NLmn) @feitnomore Hey. How did you solve Error : [ 'Failed to connect client peer, please check the configuration and peer status' ]
I also have the same and stucked here
Check you have the correct config.json running
Im note sure what should I write to client part
I dont know what is my client name
if you are sure the config.json is correct, you may need to add the env var CORE_PEER_GOSSIP_EXTERNALENDPOINT pointing to you peer addr on the peer process
here I use client-1
client name I don't think is the problem... Orgs, Channel, and Peers should look the same as the network
okay let me check i hope i ll pass this error
noone on the environment? I only see the peer from Org1MSP... I don't see orderer and I don't see the peers for other networks... Each org should have its own explorer?
Sorry I couldnt make that far

as you can see, the peer has joined the channel, and it can process transactions
even more, my endorsement policy requires at least 1 peer from each org to endorse the transaction before accepting it
and, since I have trnasactions being accepted, it means the peers are communication well
can you list what you have under /crypto-config/peerOrganizations ?
sure

@feitnomore : someone once said "the worst thing you can do for an open source project is to find a bug and not report it". You may be having the same problem as someone else. With a bug report, the more people that report it, the more likely it is that it will get looked at and fixed. I know it is a bit of effort, but you do have the most information on your environment and setup that will allow for the bug to be better able to be triaged and fixed.

@nfrunza Does tlsCACerts support specified a certificate chain file?
When starting node process, it is always impossible to establish a TLS connection.
I really need help.Thanks.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=4jaa4Feihhb8ykEoP) @praveen.aloker what is your question after you change the config?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=nvZcGqyuPqRpnd6Bz) @praveen.aloker which version of explorer you use? is your fabric using fabric-ca? did you verify the fabric is running? can you run from fabric CLI $peer version, $ peer channel list
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=bCZGqHCSvFP7QPzRu) @thomasland If you fabric uses fabric-ca explorer will now work

I need to learn Node and English...
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=pJHMLCZAcXjgKnJGD) @thomasland well you will need at some point
when I click on my chaincode, I get "location not found"
any way of troubleshooting it?
think I've found the problem
no, haven't figured out
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=MkGyxmoujXQTMP827) @feitnomore locally we used to lookup in path, in docker this doesn't work, and there is a jira for SDK for Node to create aan API to get the source code from fabric
mine is in go
ok, gotcha... read really fast and didn't payed attention
that's great... that way you guys will be able to retrieve the chaincode source using Fabric Node SDK
and the path won't cause any trouble
correct
@nfrunza With fabric version 1.2, Explorer is running fine with fabric-ca..
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=ABPjppT658pqrZEQa) @praveen.aloker could you show your config.json file?

got an interesting observation regarding explorer...
the dashboard screen uses the client/browser timezone to display the data
and not the actual dates of the blockchain network
in other words, my blockchain is running on a 2+ hour timezone, and on the dashboard, the graphs reflects transactions that happened only until the date on my desktop computers (2 hours earlier)
however, if I go to transactions tab, I can see transactions that happened in the future (2 hours ahead)
don't know if I could make myself clear

Hi there. Has anyone been able to get explorer 3.8 working in docker with the HLF 1.3 first-network sample network? I have 3.7 working with the 1.2 sample network, but when I upgrade to 1.3/3.8 using the exact same config, explorer seems to just hang on startup, and the site won't load (connection refused). I can then revert back to 1.2/3.7 and it works with no issues. Are there any special "gotchas" required to get it working under HLF 1.3?
BTW, I'm using the deploy_explorer.sh script to deploy explorer, and I'm removing all blockchain-explorer containers and images, and running ./deploy_explorer.sh --clean whenever I switch between versions to ensure that I'm starting with a clean docker setup each time.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=mYehmZ3oK6QchQsYm) @masterofimages switching between fabric versions need to be verified after you do this, if you do locally you may have to update fabric samples binaries
@nfrunza As far as I can tell, all binaries have been updated, as reported by byfn.sh (which verifies the version and reports 1.3.0). The network is built and verification checks run successfully, so I can´t see why explorer isn't working. I have exactly the same behaviour with another network running under HLF 1.3 (i.e. chaincode execution and node.js apps work fine, but explorer doesn't load). I then replicated the issue using the sample network to ensure it wasn't an issue with the network I was using.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=ykKxEWwC8rPFBDhRD) @masterofimages after you switch fabric versions, did you run blockchain-explorer/app/persistence/fabric/postgreSQL/db/createdb.sh script
@nfrunza Not directly, but I'm using the supplied deploy_explorer.sh script to build the containers, and this runs createdb.sh.
you're right, --clean will rerun
That´s right. I had to generate the config.json for the sample network based on the example, but that´s pretty straightforward, and it´s exactly the same as the one I'm using with explorer 3.7, which works fine.
I can provide the script I´m using to build and deploy explorer if that helps, along with the config.json file. All I'm doing is running this after rebuilding the sample network with the relevant version (using bootstrap.sh) and supplying it with an explorer version (3.7 or 3.8). The script then executes the clean, checks-out the correct version, copies the config file into the correct folder, creates a symbolic link to the crypto-config, then executes the deploy.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=8qSsiXFrBHWQ3dcSQ) @junki Is your fabric located on the same machine, or is remote? do you run explorer in a docker? if yes , look at this sample . configuration, start from LINE:193 /blockchain-explorer/examples/net1/README.md
Has joined the channel.
Has anybody tested explorer with v1.3 successfully?
This is the error I am unable to resolve with v1.3

@nfrunza thanks for the suggestion ... tried it but , didn't help. Challenge is that there is no error to get an insight on the issue

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=TK8PtjBNjKZoLnDNG) @longnv1a An chance you could elaborate please? Are you able to run explorer against the first-network sample using the standard deploy_explorer.sh script supplied?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=NiFEgrNft7DsjqDy6) @nfrunza Thank you!^^
Excuse Me. I have a question!. Where does the hyperledger explorer information come from? PostgresSQL?, peer container? orderer?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=pR69vysiiBkKgEebv) @masterofimages I am not using the first-network example, we create our own network.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=htgfCN4M5EgmrCXgw) @junki Depends what you mean by "information". The initial configuration is done via the config.json file which you have to supply. This contains all the connectivity details required to connect to each node on the network, as well as certificate and key locations. Once explorer connects to the network and starts reading the ledger, this information is then stored in the PostgreSQL database.

When a transaction occurs, it is stored in the database. Is it reading the database and printing it to the Web?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=4veZiT67qCsQXKHgD) @junki Fabric stores transactions/blocks in internal fabric DB(levelDB, or couchDB depending how you start your fabric), Explorer queries block/transactions from fabric and stores in local postgreSQL DB that is in sync with fabric, so it would not query fabric every time you need to preview, search blocks or transactions

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=BwKAiscJBMmctnPCS) @nfrunza Ok. Now I see the problem. There was a change made to deploy_explorer.sh on October 4th (by you) which switched the exposed port from 8080 to 8090. However, all of the documentation still refers to port 8080! I don't know why this change was made, but it should either be reverted, or the documentation updated accordingly.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=KyQfHkpcSraGdMAn6) The reason was plain for me to see in the "docker ps" output when I checked the port mapping. Of course, this should have been the first thing I checked. Lesson learned!
@nfrunza BTW, the client and fabric versions reported by the application are wrong for release 3.8. It still reports 0.3.7 and 1.2.

Hi,
I need some help regarding Hyperledger Explorer configured with softhsm (pkcs11).
All the doc deals with a config.json file which seems to be our network and our hyperledger config.
How do you configure your network if Hyperledger uses PKCS11 crypto instead "file" crypto ?
For example,
"Org1MSP": {
"mspid": "Org1MSP",
"fullpath": false,
"adminPrivateKey": {
"path":
"fabric-path/fabric-samples/first-network/crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/keystore"
},
"signedCert": {
"path":
"fabric-path/fabric-samples/first-network/crypto-config/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/signcerts"
}
},
AdminPrivateKey is unknown since it's in my softhsm...
All Hyperlerdger Explorer solution (included FabricClient) is based on configuration and file crypto, it's impossible to configure a pkcs11 crypto...
Am I wrong ?
Thank you foir your help.

Any thought?
are you using explorer from the branch release-3.8? I'm asking cause for me master didn't work..
I am using master branch right now
try to switch to release one and start explorer not from docker
Alright let me try
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=GJRAEgeZkfYi35jPW) @ihormudryy yup, that was it! :D
I have another question now. If I have 2 orgs on 2 different machines, do I need to set up a network for each one?
Right now in my setup each org has 2 peers and explorer only shows the 2 peers from one org, not the others
Has joined the channel.
Or do I set up another client?
So a little more background on that:
I modified first the config file to math my setup, both orgs and each peer on the peer section. When I run the main.js it works without errors but when I go to localhost:8080 it only shows the 2 peers of the first organization, nothing for the second one...
On the client section I have the name of the first organization, and if I switch to the second one to test it out I get this on the app.log
`[2018-12-03 11:37:33.020] [ERROR] FabricClient - { Error: 2 UNKNOWN: access denied: channel [] creator org [SupportMSP]`
And in the console
`Error : Failed to connect client peer, please check the configuration and peer status
Info : Explorer will continue working with only DB data`

Hey everyone, I'm planning to add support for HyperLedger Iroha, but I have a following question. Currently a lot of functionality is entered around a concept of channels, which is specific for Fabric. As there is no channels in Iroha, what should one do?

Hello All, Is there any current support or scope for any future support for wallets within hyperledger-explorer?
The aim is to scope a user's view of blockchain explorer based on their ACL rules on the network.

@nfrunza I already have this variable set, its related to explorer not fabric, since whichever peer i configure as first, shows up as active. Do you mean that , discovery feature automatically should list all peers even if one is known?
Ok it was due to absent anchor peer
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=gSfX4di5Yf3FFzwpd) @ArpitKhurana1 would you be able to describe your case and we can add to troubleshooting doc., so other developers can benefit?
@nfrunza yes ofcourse, you were right about service discovery
I guess the explorer gets the peers by querying the one default peer of channel. Even if everything was working in my channel, still I had slipped setting the anchor peer as it was just single organisation
I redeployed everything again and setup anchor too, that made it work, I don't know how much anchor peer configuration helps in gossip or service discovery. But this worked
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=PJyiK5gEnHwRQahb2) @ArpitKhurana1 i'm glad that it helped, would you be able to contribute to Explorer?
@nfrunza For the doc you mean? I can but, I still don't have the exact info about why this worked.

Edit: The reason is the container blockchain-explorer cant reach/ping the peers which are listed as down.

@jeevas Now that we have setup Hyperledger Explorer for our own Fabric network, we are trying to explore all the features available in the explorer tool. Do we have any official documentation explaining the features available in Hyperledger Explorer?
@nfrunza thanks for the help. I gave up on trying to deploy Explorer from the code and moved onto the Docker deployment option. However, I am not on the instructions here: https://github.com/hyperledger/blockchain-explorer#Database-Setup
I setup the dockerConfig directory as it says here:
"Create a new folder (lets call it dockerConfig) to store your hyperledger network configuration under examples (mkdir -p ./examples/dockerConfig)
Save your hyperledger network configuration under examples/dockerConfig/config.json.
Save your hyperledger network certs data under examples/dockerConfig/crypto."
however, I am now a bit confused how the details of what exactly needs to go into these two folders. The instructions are really not that good as this is way to vague to just say to throw the config settings into those folders. How is anyone new to using explorer supposed to know what to put into those folders with no details at all?
oh, I guess I do see an example under the folder "net1"
I will attempt to use that as an example. Just wanted to point out to whoever worked on the Explorer doc that it could use some elaboration on that part.
;-)
I'm getting an error when trying to run the script to start the Explorer docker containers:
docker: Error response from daemon: user specified IP address is supported only when connecting to networks with user configured subnets.
I have the byfn running and using the net_byfn network
This is the default setup for using docker to deploy Fabric samples and the Explorer so I don't understand why it is giving this error.

Hello, can someone tell me how can I see a base URL for hyperledger explorer, I don't want it to be at the root base URL, want something like http://localhost:8080/mynewbase/
Has joined the channel.
Hello. I'm having a lot of trouble configuring explorer and getting it up and running. I am using the dockerized version, and have set up my network information in config.json. My network is a composer network, based on the "fabric dev servers" example at https://hyperledger.github.io/composer/v0.19/installing/development-tools.html. After lots of trial and error, I have Explorer starting up with no errors in the log. However, when I browse to the correct location, or use curl on the explorer docker container, I get either "Connection refused" in curl, or "localhost" didn't send any data" in Chrome on the host. The log is clean - no errors. The last few lines are:

The web client never got built somehow.. building it manually from the client directory gets me a web application, but I see 0 nodes, 0 blocks, 0 transactions, 0 chaincodes (I should have all of these)
@CraigDrabik try using this example as a reference: https://github.com/hyperledger/blockchain-explorer/blob/master/examples/net1/README.md That helped me.
I've been going over and over them all for the last two days. There are two things I don't understand at the moment:
1) . The logs seem to indicate that it's looking for a database installed on the same machine as the one running the explorer GUI/API. Are there postgres dependencies I need installed?
2) I'm seeing
Sync process is started for the network : [hlfv1] and client : [client-1]
<<<<<<<<<<<<<<<<<<<<<<<<<< Synchronizer Error >>>>>>>>>>>>>>>>>>>>>
Error : [ 'Failed to connect client peer, please check the configuration and peer status' ]

in the logs. Playing with the sync setting either lets the application start up, with no data, or not start up, with the above error. I've checked the config.json settings against what's in DevServer_connection.json (in my composer network), and I can't see any differences.
I mean, did it fail to connect because there's no route? Expecting grpcs but used grpc? Using invalid credentials?
yes you need to install and setup postgres in order for the local install of Explorer to function.

I have followed the instructions very carefully, but when I get to this point I open up http://localhost:5000/#/ in the browser and I see the Hyperledger Explorer loading page for a split second but then it does not go any further with loading.
I actually did have the Explorer web UI running previously but now I can't seem to get it working.

man this react app is REALLY DIFFICULT to get working properly.
It would be nice if this forum was a bit more active. I have been trying to work with HLF and spending a lot of time learning it but it is difficult with such an unresponsive development community TBH. When I ask questions the quickest response time seems to be the next day or even days later. I really though HLF was a much more popular technology on the rise. Is there another support forum somewhere that is more active???

React and Angular are normally built with dev mode when in development and production during deployment. Dev mode gives on the fly updates to the React app without having to even reload the browser. More importantly without having to rebuild the app to production build.

Can anyone explain me how to use this /metrics (http://SERVER_IP:8443/metrics) endpoint to display result as graph representation.
@kmohanar1 I think fabric just provides an exporter for statd or Prometheus. You still need to use Prometheus for crawling metrics exposed by fabric. I have an experience playing around this feature in fabric 1.2. feel free to DM me if you have any question.

Hi. I'm trying to connect hyplerledger explorer to the basic-network example. Apparently, the basic-network example doesn't have tls enabled. So, the defaults in explorer give "Handshake failed with fatal error SSL_ERROR_SSL: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number."
So I set tlsEnable to false, and set all grpcs protocol references to grpc and now it's just acting like the peer is down, but it is up. I have hyperledger composer already up and running and talking with the peer.
Is this a common issue when setting up explorer with the basic-network example? Any suggestions would be very helpful. Thanks.

Hello, I'm currently trying to set up explorer within a kubernetes cluster and with a CA server. Fabric is all up and running but I'm failing to figure out how to wire up the explorer configuration. I'm not using the fabric-sample, this is my own network, and because of the CA I don't have the example crypto-config folder. Long story short, I'm eager to get more debug on what I may have done wrong. My current error on explorer is:

I have questions about config.js. If anyone can help me, I'm grateful!
I have 8 Peers in my network. I only added 2 Peers in my config.js.
The fact is that Explorer displays all Peers that are not in config.js with Status = DOWN. Only the Peers in the config.js are displayed correctly, ie with Status = RUNNING.
My question: Is it mandatory to put all Peers in config.js? Is not it correct to get Satus from all Peers regardless of what's in my config.js? That is, you should connect to the network and get all the Peers infos automatically. What do you think?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=Lvqm9ybuCkJmAwwvf) @erickrettozi did you configure the peers to be discoverable?
@nfrunza No config.js?
I did not configure all Peers, only 2 out of 8. But the explorer takes almost all the infos of all Peers, even the other 6 not being in the config.js file (Strange no?), But the status of Peers that are not in the config.js appear wrong.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=zmux6ganfcBBNtBBL) @erickrettozi yes, explorer uses discoveryresults
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=zmux6ganfcBBNtBBL) @erickrettozi yes, explorer uses discoveryresults, would you bea able to configure and give a try, i'm afraid this may not be tested, thank you

Hello, I'm running in a strange issue
I have setup explorer with two orgs (like this config file https://github.com/hyperledger/blockchain-explorer/blob/master/examples/net1/config.json)
But when I use the org1 as client it fails but with org2 as client it success.
In the peer log of org2 (when using org1 as client) I see that it receive the wrong MSP, does someone know why ?
It seems that is is trying to use the client (setup as org1) to connect on peer-org2, can we setup multiple client and tell which client to use for peers ?

Hi, I'm trying to setup the explorer with a network that uses ssl certificates issued from an intermediate ca. My network is correctly set, but when trying to start the explorer I get the following error:
`E0214 12:01:56.341531064 176370 ssl_transport_security.cc:1227] Handshake failed with fatal error SSL_ERROR_SSL: error:14090086:SSL routines:ssl3_get_server_certificate:certificate verify failed.`.
In the config.json, I set the tls root certificate under the tlsCACerts.path property of each peer. I tested with ssl certificates issued under the root ca and everything worked fine. Can anyone help me with this setup?
If I understand well, HE uses the discovery API, right ?
If I understand well, HE uses the discover API, right ?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=cf735Q6iwiKwKuaMK) @Kelvin_Moutet correct
So, it's pretty strange to have a network/config json file if we have the discover api
https://hyperledger-fabric.readthedocs.io/en/release-1.4/discovery-overview.html
Because we juste need to setup a client along one peer and the rest can be discovered non ?

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=pkwSZ5szRrxdnwd3S) @Kelvin_Moutet discovery was added in fabric 1.1, and explorer just made adjustments, and the other reason is to get the peer statuses
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=H9m9fDausAgfPe7L5) @Kelvin_Moutet i believe so, and the fabric needs to be configured properly

@nekia My current config looks like this in the channels section: ```

I was already trying to add an orderers section, with the same format as peers.
Looking at the sample you linked to, it seems that that format is wrong and should just be a list of strings, not empty objects. Is that correct?
Something like `"orderers": {"orderer0"},`
I don't think it's the same format as peers. You need to add with array format.
```
"mychannel": {
"peers": {
"peer0.org1.example.com": {}
},
"orderers": [
"orderer.example.com"
],
```
@nekia I confirm, my format was wrong and the one you proposed allow me to successfully launch the explorer. Thank you very much
If TLS enabled, you will also need to add tlsCACerts setting for orderer.
:grinning: Great!
I think It would be very helpful to update the samples on github as such for the next people who would try the new explorer.
Yes, you are right. We are working on it.

Thank you nekia :)
If you change your client to :
```
"client-1": {
"tlsEnable": true,
"organization": "Org1",
"channel": "mychannel",
"credentialStore": {
"path": "./tmp/credentialStore_Org1/credential",
"cryptoStore": {
"path": "./tmp/credentialStore_Org1/crypto"
}
}
}
```
Does it work ?
Yes it works.
It surely comes from here non https://github.com/hyperledger/blockchain-explorer/blob/5941ea1e516d7cb0f46bac4ef9ba9bed2769b4ec/app/platform/fabric/FabricClient.js#L149 ?
It takes the first peer on the list, whatever the client is, but we have to match/restrict the peer chosin with client org
(I'm not familiar with Javascript, so it's just a supposition)
(I'm not familiar with Javascript and the HE code, so it's just a supposition :) )
Thanks! We'll look into around here closer.
@garunkumar450 There were same reports in this room before, at that time using new explorer was one of the solutions.

Hello!
The need to have to configure each of the Peers in the config.json file is something I would not want to have to do. For me, the ideal would be for Explorer to grab all Peers and their respective STATUS automatically, without having to add each of the Peers in the config.json.
I know that for this to work, it is necessary to change the code of the Explorer to begin to recognize the Peers in the network automatically.
Has anyone here had to do this?
Is good idea change this logic on Explorer?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=432Na8CXNgyj6y7SR) Resolved. I had to define config.json pointing to paths inside the docker container and not on host machine.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=ZwazjXterpCREvMmh) @garunkumar450 can you tell which version of node you're using?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=AZdf2qFoLdfgMrJNk) @PMoura great, you're running explorer in docker?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=aiHjMJy2cQaEHtphx) @erickrettozi we started to work on this, to use the default channel, peer, and use fully discover service, the other is to have configured properly fabric network with discover service
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=w65bHsYYnCvPR8yXA) @nfrunza Yes, I am.
Thanks to all.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=Lovhe5uWF2Np5odbJ) @nfrunza @nfrunza Thx!
I'm thinking of implementing this. What you think?

@all did anyone tried to connect explorer to AWS fabric network from local workstation ?
Has left the channel.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=b3CQ4oW483iJE5Dh5) Hey guys, I asked this question yesterday and I still couldn't figure out how to configure the explorer to work with SSL certificates issued by an intermediate CA. My network has some requirements on this, so I would be very thankful with any insight on how to correctly configure this.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=8m6zzWrtAS6NFXoiR) @ftfnunes read here, you may need to update the config.json, and credentials https://github.com/hyperledger/blockchain-explorer#configure-to-work-with-fabric-ca-server

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=xW79fCbhkP9XtTNYN) @bh4rtp you need to inspect you fabric network, defined domains for the peers, orderers and organizations, if you use fabric samples it is possible that there is a conflict, can you run in debug mode, do this 1. $export HFC_LOGGING='{"debug":"console"}' . 2. $node main.js follow on debug logs
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=erQ6dsSipucpNnJdT) @garunkumar450 do you run a fabric-samples network?

@nfrunza yes, i am taking `balance-transfer` as example, but the network is customized. what is the conflict when using fabric samples?
@nfrunza finally i found the reason. it may be because of timeout. after display `Please verify your network configuration, database configuration and try again`, i continue to wait and about 2 minutes later, the browser shows the network correctly. so how to adjust the timeout value?

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=FajiqF5J5XFkfxKtR) @nfrunza Thank you for the help, but I'm not using fabric-ca and I was not able to find out the changes i need to make to the config.json to make this work. My config.json is already configured like that, but maybe I need to configure my SSL intermediate CA somewhere since the peer does not return it?
Hi, I'm using explorer v0.3
Hi, I'm using Explorer V0.3.9 , Fabric 1.4 and Fabric-CA
When I try to deploy the Explorer the logs from docker container blockchain-explorer says:
`(node:7) DeprecationWarning: grpc.load: Use the @grpc/proto-loader module with grpc.loadPackageDefinition instead
`
and the logs from logs/app/app.log :
`[2019-02-18 15:38:41.602] [DEBUG] FabricClient - Successfully created user [client-1_OrdererMSPAdmin] for client [client-1
[2019-02-18 15:38:41.603] [DEBUG] FabricClient - Client.createUser missing required organization.
`
The config.json is ok because the Explorer's user is regitered well. Any idea?

Are you disabling TLS on your fabric network ? @FlorianStoica
Why does explorer need `credentialStore` path? Isn't `adminPrivateKey ` path sufficient?

It is quite complicated to understand hyperledger explorer ... :(
if you do not work with the network that is previously established ... I do not know how to proceed with a network that I create from 0 ... :(
by the way ... already solve the problem of the DB
1 - ubuntu@ip-10-0-1-175:~$ sudo -u postgres psql
2- copi paste -> explorerpg.sql
\l see the created fabric explorer database
\d see created tables
and finish
3- \q exit
change .txt to .sql

You help mount hyperledger explorer without using the template fabric-samples.git ????
I mean to ride explorer from a fabric created from 0 ???

Hi all, I'm running a Fabric v1.4 network and Explorer v0.3.9.1 and it works fine. If I add CAs in the network, the Explorer still works fine.
My question is: Why I need to configure the CAs in the config.json?
Does HE support mutual tls ?

Hi everybody. Does anybody have a good tutorial on how to run Hyperledger explorer for a network that is on an IBM Blockchain Platform starter instance?

starting explorer with docker-compose yields an error about not being able to find the locate command. The instalation of the command is not present in docker-compose.yaml sample, neither is possible to install it once you are inside the container.

Hello guys! Once the explorer is built, is it possible to avoid launching the application through the `node main.js` command and serve it through an http server such as nginx? Has anyone tried this approach? Thank you!
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=9Dd2TxCTvnCsGpHsZ) @vanitas92 very interesting concept, main.js exposes the routes, starts the connection to FLFabric and much more, maybe there is a way nginx can execute the main.js
@vanitas92 just use docker for explorer (and add it to existing network where your Fabric nodes are) -> they will communicate via http://containername:port and then you can also add nginx and expose explorer from docker network to host via nginx. Hope this isn't to complicated. :)
I don't know where to post this, link on https://www.hyperledger.org/projects/explorer -> join discussion on chat is wrong :)

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=G3sEn9A94gfNdTDZS) @edisinovcic I am using a custom dockerfile for building the explorer but i would like to use advantages such as multi-stage building in Docker to put the compiled code of the explorer into an nginx server and deliver a minimum image to the server where the explorer would run. It would be a nice to have.
@vanitas92 that would be great. If you succeed let me know. Tnx ;)

Hi I am getting the following error: `error: [FabricCAClientService.js]: Failed to enroll admin, error:%o message=Enrollment failed with errors [[{"code":20,"message":"Authentication failure"}]], stack=Error: Enrollment failed with errors [[{"code":20,"message":"Authentication failure"}]]` - any hints?
I am guesing it needs the CA admin password? how do I set it?
@edisinovcic Many thanks, but is it downward compatible？for example,blockchain-explorer/release_notes/v0.3.6.md writes "Support for Hyperledger Fabric 1.2", so how about the fabric 1.1?

so what may result to these errors, the npm test is ok
@touchingsoil are you using docker-compose for running or ./start.sh and ./syncstart.sh scripts?
You need only to modify config.json to your configuration (there are multiple configurations depending if you are using cello or composer or plain fabric). Here is the link: https://github.com/hyperledger/blockchain-explorer/tree/release-4.0/app/platform/fabric
I'm not sure about backwards compatibility, you will need to ask devs that. :)
@edisinovcic I am using the version 0.3.5.1( because of the fabric 1.1) via the ./start.sh and ./syncstart.sh scripts. In this version ,there is no such files under app/platform/fabric, so is this version still workable?

hi everyone! I have a doubt, when I setup the explorer with the first-network sample, the two nodes of the org2 are in state running and the peers of the org1 are in state down, why is this?
when I check the state using docker ps, peers of organization1 are running
any idea what happens in the explorer?
@Javi see if the peers have gossip external endpoints defined in their docker-compose.yaml (environment).
yes @SashaPESIC all peers hace these env var defined
yes @SashaPESIC all peers have these env var defined
Hi all,
I run hyperledger explorer but I saw only 1 peer. Although, I config 4 peer in hyperledger fabric.
Please help!!

were they all in the configuration transaction you created for your channel @duy3991 ?
Has joined the channel.
after deploying on cloud I have the following error on explorer error: [Channel.js]: Channel:mychannel received discovery error:access denied, do you guys have any idea ?

Also "[INFO] pgservice - Please set logger.setLevel to DEBUG in ./app/helper.js to log the debugging." level is set to debug but still the same error message apears in db log
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=psWwtH2eFuxk2sC4H) @Aniket.1 Yes. I check the log of all peers have newly created block data :)
What is the use of client in config file and how to configure one?
@ygnr for me, client config show status of the peers that belongs the indicated organization
If I put into client-1 -> name `Org1`, only peers of this organization appear as running, other peers from other organizations shown as down
I don't know why this happens, maybe anyone can explain this. The documentation says that when the `syncstar.sh` is called: `pass network-id and client-id to start specific client sync process`, but, this can affect how the peers status is shown??
@Javi I have the same problem here :/
Does blockchain explorer support kafka orders(especially in v0.3.5.1)? so how to write the order info in config.json?
I deploy the blockchain explorer , i got the right answer from direct visit to http://localhost:8080/api/channels, but got error: "TypeError: Failed to fetch" when press the "try it out "-->"execute" button in the http://localhost:8080/api-docs web page.

Is your fabric network joining to any channels? @FlorianStoica when I started explorer without channel joining, i might see error you mentioned.
@edisinovcic you solved the problem?
I started manually anothe client using `syncstart.sh network-1 client-2` but it does nothing....
peers still shown down
@nfrunza can you provide any hint?
I keep on getting `/bin/sh: locate: not found` any one facing same issue?
I have 4 peers in the fabric network, while the explorer only shows two of them, how can i fix it? i've checked the ports and config files.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=fXmpn6hsC5CzrTfpT) @Vampire Me too. But explorer only show 1 of them :(
Have you guys mentioned all of them in config.json?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=QAFdFXB3NqSyCNgNf) @Aniket.1 yes. This is my file config.json

all 4 peers have joined composerchannel?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=j2RZQKkTmzG2tQyvD) @Aniket.1 yes.
check app logs, is it discovering the other peers or any error is there?
@duy3991 same error
explorer only show running peers of the org indicated in client
in your case only peers from Org1
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=rwivN24RJ6xzjBoc3) @Javi same here
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=5GYWHaDWhS4tanh5D) @ygnr I have the same log, but it doesn't affect the performance
Has joined the channel.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=PvosKTZbXniuFdHjG) @AlbertCL locate is the command the app uses to find your chaincode files. if you are running as a standalone (outside of docker), just install mlocate and you will be fine.
Thank you for sharing an issue you have. I've not analyzed the detail of this issue yet, but I currently recommend using docker-compose to bring up your explorer with your fabric network because deploy_explorer.sh has not been maintained, unfortunately.
https://github.com/hyperledger/blockchain-explorer#run-hyperledger-explorer-using-docker-compose @zhasni
thx @nekia
I'll try this way.
same result with launching manually the docker-compose.
I tried the local installation
```
cd blockchain-explorer
npm install
cd blockchain-explorer/app/test
npm install
npm run test
cd client/
npm install
npm test -- -u --coverage
npm run build
```
also not working.

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=8FBANKjutReGi844j) @zhasni First build the docker image from source code, inside your v0.3.9.1 code do: `docker build -t hyperledger/explorer:latest . ` next `docker-compose up`
Did you configure external network to net_byfn in your dicker-compose.yaml?
@zhasni
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=05dd9066-529f-460a-975a-b480a63407a4) @nekia You do not really need to configure the external network. That only means that you have created a docker network earlier and are refering to it in the docker-compose.
How to configure explorer docker image so that when the host restarts it automatically restart the explorer (currently had issues saying that channel already exists)
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=aD8cd4SsmMSW3bb7h) @FlorianStoica theoretically if you restart you fabric network explorer will go down, we do not handle retries, maybe we should for some interval let say 10 min max, the question would be how do you restart your fabric, will your channels be same as before restart? if genesis hash is changes, and or crypto we would not be able to reconect.
Let me add a little bit information. I doubt that [this configuration](https://github.com/hyperledger/blockchain-explorer/blob/v0.3.9.1/docker-compose.yaml#L10) doesn't align to net_byfn that is defined for first-network. If not, explorer container can't talk to the underlying fabric network.

Hi @nfrunza thanks for your answer, Fabric 1.4, exploerer tag v0.3.9. I modified `docker-compose.yaml` file according to network name, created proper directory in `examples` directory and add proper `config.json` file and `crypto` directory. My assumption is that `logs/app.log` is placed in ` hyperledger/explorer` docker image ? If so i can't access them because docker is closing after encountering above issue so cannot log in into that and see content.

When postgres container is started the first time, the database for explorer is setup by running createdb.sh through docker-entrypoint-initdb.d
Could you try again after doing 'docker-compose down -v' to remove all persistent volumes for explorer/explorerdb containers? @alek
Hi @nekia thanks for your response. I already done that. I even removed images and they were rebuild from scratch and issue is the same
When I comment out [here](https://github.com/hyperledger/blockchain-explorer/blob/v0.3.9.1/docker-compose.yaml#L23), I get the same error. So I suspect that the initialization of database is failed. Could you share the log of explorerdb container when it's started right after removing container volumes ( running docker-compose down -v ) ? And I recommend you to use v0.3.9.1 ( the latest tag ).

You seem to be in explorer, not in explorer db. Is that right ?
yes, i resolved prevoious error by dividing docker-compose file into two separate parts: explorer and exploerer db, run explorer db, manually executed `createdh.sh` then i start explorer and encounter such issue. So generally first issue is resolved and new one emerged
OK
@nekia is there any way to change logging level to DEBUG of explorer to find out which part of `config.json` caused an issue ?

So how can i make auto updated

I have setup balance transfer from fabric-samples and now wish to setup explorer. I have the requirements, cloned repo, setup the database. Now I need to change the values in config.json, namely the path to the keys and certs. Can anyone tell me how I go about finding these paths when my balance-transfer app is running inside docker containers?
Is the term, crypto-artifacts? for the keys and certs?
I am connecting to the containers using Sudo docker exec -it ‘container-id’ bash but not sure where I might find the crypto artifacts
crypto-config seems to be the folder im looking for

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=qkqe6Jm7Jig6asRTt) @nfrunza This means if I use fabric 1.2 and composer version 0.20.x I will be able to see results of composer sample network on explorer
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=MrmFrfRvTncSrqbq8) @garunkumar450 Are you using fabric-sample as fabric network, I have noticed this when switching from one network to another, a solution would be to kill the docker and restart , docker stop $(docker ps -a -q) && docker rm -f $(docker ps -a -q)
rm -rf ./crypto-config/* && rm -rf ~/.hfc*

Hi so i am trying to connect hyperledger blockexplorer with fabric network that contains 3 organizations and 1 peer for each organization. Now I am configuring the explorer such that I am adding only 1 organization in config.json under "organizations" object. The idea is that in a consortium all the participating organizations would have their separate nodes and they would not share the private keys among themselves. So for each organization there would be a separate instance of explorer, is this right approach?
also if i do it this way, everything seems fine in explorer except that only the peers of the organization i have added in the config file are shows as running and all the other peers are shown as down. Is this normal behaviour? Why is it showing those peers down when clearly it is detecting those peers. Also for the second instance the same peer is in running state and others are down.
Are there any players (Companies) available with blockchain based solution in Surety bond industry, specifically in North America
So in the end this is how my three version of explorer appear for each organization

a simple question, how can i use v0.3.9.1 version, my client is v0.3.9, should i add ".1" in package.json or how can i get 3.9.1 version

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=M6EzdhiBMNtQotzw2) @Tommy109 https://github.com/hyperledger/blockchain-explorer/blob/master/appconfig.json
that file is set to 8080 but when i run the client app it attempts to use 5000
Clipboard - May 1, 2019 2:40 PM
@nfrunza how can i change this port? as i need 5000 for another app
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=8jkPdt7sSfxb8aTvJ) @Tommy109 you're running in dev mode, from the client, we do not have such instructions, i think you can pass as $ PORT=9999 client -s build
ok, thanks @nfrunza
Hi guys. I am using explorer from docker image. Recently i have been getting this error when i visit the Network page of the explorer (nothing shows up). Is there something in the code that is making a problem? Anyone encountered this yet? Everything else is working on the explorer...

Hi, for some reasons some of the peers in "peer status" are shown as "down" although their container is running, anyone seen this problem before ? My config.json has all 3 orgs as clients at the start of the file
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=hRz4w9sTrbNwK9Z4G) @colasga Do all of your peers have external gossip endpoints defined? If not, the explorer is not going to be seen.
all my 6 peers (2 per orgs) are defined as follow :
peer1.org2.example.com:
container_name: peer1.org2.example.com
extends:

service: peer-base

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=XrEe5ShXRxvxHwsc3) @SashaPESIC is something wrong with the definition of my peers in docker ?
(obviously i change the address of each externalendpoint aswlel as bootstrap)
I'm actually not sure what port I should put as external gossip endpoint
@SashaPESIC ， my problem is same as @colasga, and please refer to this link:(https://stackoverflow.com/questions/54230775/issue-in-creating-multiple-peers-in-hyperledger-explorer/55655427#55655427).
it seems like someone have same problem before. and for now, i have not found out any solutions.thanks anyway.
@nfrunza hi, may i ask if there is any effective solution for this question?
before, nfrunza suggest to refer this document for the problem(https://hyperledger-fabric.readthedocs.io/en/release-1.4/discovery-overview.html), but i still have not figured out how?
You should specify the port number available within the docker network for CORE_PEER_GOSSIP_EXTERNALENDPOINT and CORE_PEER_GOSSIP_BOOTSTRAP, it means 7051, not the mapped one (ex. 10051). @colasga
Hey, sometimes several blocks are registered twice in the database, has anyone ever had this problem before ? And if so how did you solve it ?

Hi everyone1! is there a way for me to show the actual transaction content (payload) in Explorer?
Hi guys, i have fabric and explorer both running and fabric is writing transactions fine but explorer is not displaying the latest transcations. It has been working previously. Any idea why explorer might stop displaying transactions on the front end?
could it be the postgres service isnt running?
did you look at the log files? any errors
my colleague got it working in time for our demo. Panic over lol. Thanks anyway @nfrunza
what was the problem?
Still waiting on word back from him to find out. Since it was previously working I am guessing it might be something like postgres service has stopped
ok
it would be in a json pretty format, we may need to add that functionality, add a jira, how about the security, it contains the crypto

thanks for your reply... I am not sure I quite understood that...how can I add it myself for the timebeing?
*time being
create a jira, so we can add that functionality

Why does explorer need to use a separate pgsql db rather than the couch or levelDB used by fabric network?
follow-up: generally speaking, how difficult might it be to modify network to use a single pgsql db instance for both Fabric and Explorer, or is this not possible due to the varying types of data being stored (aka: KVS v. RDS)?

I try to run hyperledger explorer(*v.0.3.9*) on my fabric network(*v.1.4*)

sometimes it takes so long to load it will bring up a message 'please verify your network config, database config and try again'

Ok thanks.
@nfrunza I have network in which there are multiples orgs and peers. In `config.json` i have just defined one org's peer and its msp. it shows the transaction but it does not show the peer in node list. why is such behaviour for explorer.
please describe your fabric network, is a sample? your OS, which HLExplorer tag you use
did you enable discovery service? see https://github.com/hyperledger/blockchain-explorer#60-fabric-network-setup---- , for: Make sure to set the environment variables CORE_PEER_GOSSIP_BOOTSTRAP and CORE_PEER_GOSSIP_EXTERNALENDPOINT for each peer in the docker-compose.yaml file. These settings enable the Fabric discovery service, which is used by Hyperledger Explorer to discover the network topology.
I am using byfn fabric network as a sample network and macos.

I am setting up explorer for fabric network which was running in some different machine(say IP 12.34.56.78),when i try to start the script start.sh from explorer i struck with this error.
Successfully connected on single instance(both explorer and fabric on a single machine) but facing error when trying to connect on different machines.
Here is the config.json file where i am changing parameters.

Please don't post all your config in chat, you can attach as a file, it's hard to read, please describe your explorer version/tag, hlfabric version, and if you're using another machine to connect to you may need to open connection to machine you installed explorer
How do you setup the json configuration so that the explorer can see more than one channel? If there is org org1, and it is part of channels c1 and c2, how to specify both thannels in the configuration file so that that you could switch channels in the explorer UI. Every example in github is with one channel...
please enable discovery service, see here https://github.com/hyperledger/blockchain-explorer#60-fabric-network-setup----
Make sure to set the environment variables CORE_PEER_GOSSIP_BOOTSTRAP and CORE_PEER_GOSSIP_EXTERNALENDPOINT for each peer in the docker-compose.yaml file. These settings enable the Fabric discovery service, which is used by Hyperledger Explorer to discover the network topology.
I'm having issue with explorer (dockers) i get errors : ```fabric-explorer | (node:1) DeprecationWarning: grpc.load: Use the @grpc/proto-loader module with grpc.loadPackageDefinition instead
fabric-explorer | 2019-05-28T21:19:39.365Z - error: [Channel.js]: Error: 2 UNKNOWN: Stream removed ```
which version/tag of explorer do you use, and hlfabric version, try latest explorer tag v03.9.3
Has joined the channel.

I follow HL explorer tutorial . especially 'database setup'. but i have a problem

I'm using 4.0 tag to build the docker, Fabric 1.4
I have these enabled for every peer. This still does not help explorer find all channels.
I have these enabled for every peer. This still does not help explorer find all channels. Also peers are not the problem, the explorer sees all of them, but still sees only one channel (that is supplied in the config file).
Every example on HF Github is a single channel example (for explorer). That is not a real use case.
On the other hand, i also have setup anchor peers for ever channel, per organisation.
So i am wondering if there is anything else to setup so that the explorer would pick up the multiple channels?

please verify DB installation, Connect to the PostgreSQL database and run DB status commands:
\l View created fabricexplorer database.
\d View created tables.
how about explorer tag you're using? please use tag v0.3.9.3
can you look in logs, logs/app/app.log ?
can you get some first 50 lines from logs/app/app.log ?
do you run explorer and fabric on the same machine?
I have also faced the same issue in setting up explorer for multiple channels. In my network, one of the organization is member of 2 channels, but explorer does not list down 2nd channel in the drop down. I even checked all the tags related to service discovery and even updated the anchor peers of that organization for both the channels, still was not able to resolve this issue. An help would be appreciated in resolving this
Which tag of explorer version needs to be used for connecting it with fabric network running on version 1.3?
see, https://github.com/hyperledger/blockchain-explorer#10-release-notes----
v0.3.8
please let me know your environment, OS, is AWS, fabric version, explorer tag or branch you use

i run same machine
if postgresql is installed on an other machine, you may need to open ip of the explorer machine on the one where postgresql is installed
Thank you for your help! It work!!!!! I made a new setup so that external IP can access it. That's Key! Thankyou so much :kissing_closed_eyes:

Hi, a basic question, can we use explorer on an IBP (IBM Blockchain service) network ?
Good question, theoretically HL Explorer can be connected to any HL Fabric based blockchain if properly configured
Clipboard - May 31, 2019 11:34 PM
please use tag v0.3.9.3
what error do you get? can you look in logs/app/app.log file?
Hello Team, Has anyone been able to setup explorer with fabric network having multiple channels ? I am able to see the explorer but only 1 channel is listed in the drop down, not able to see the details of my second channel, however I am able to do transactions in both the channels, so I guess fabric-network is properly configured.
Hello Team, Has anyone been able to setup explorer with fabric network having multiple channels ? I am able to see the explorer but only 1 channel is listed in the drop down, not able to see the details of my second channel, however I am able to do transactions in both the channels, so I guess fabric-network is properly configured. I also checked the `channel` table in explorer postgres db and there was only 1 record present, ideally there should be 2 records (for both channels). Can anyone guide me , how data is pushed into these tables?

Hi,
I am trying to get HL Explorer running on my local machine. I am following these steps: https://github.com/hyperledger/blockchain-explorer
But when I try to execute ./main.sh install, I get the error above.
Can anybody please help me with this?

please do not run as a root user
or do this from directory blockchainExplorer run$ chmod -R 775 blockchain-explorer/
Thanks for the quick response. It turned out that I had bad nodejs version installed... I didn't check the prerequisites carefully enough.
are you able to run explorer?
yes
do you use a sample from fabric-samples
yes, the first-network
ok
Guys, can anyone help me on this, not able to resolve it from quite some time now..
Hi, is there a single document that lists out the capabilities of Hyperledger Explorer? From what we have seen so far in explorer, we think adding few more features would be useful. Please can you suggest the right forum to make these reccommendations?

I am using the following configuration for discovering service, the bootstrap and externalendpoint they differ just to enable HA on both peers:
```
- name: CORE_PEER_GOSSIP_EXTERNALENDPOINT
value: peer0-oe1:7051
- name: CORE_PEER_GOSSIP_BOOTSTRAP
value: peer1-oe1:7051
```
@here We need people to help on creating documentation for the HLExplorer, we want to use https://docs.readthedocs.io/en/stable/intro/getting-started-with-sphinx.html , please any volunteer would be appreciated
what is "HA" ?
High availability, in case one peer goes down, the bootstrap points to other peer to get the missed transactions when the peer was down

Hi guys, @DavorKljajic and I created an article about Blockchain Explorer. In this article we used our custom network with 4 organisations, 1 channel, TLS, GOSSIP etc. We explained all errors and how we resolved them so maybe it could help to all of you having issues with it:
https://medium.com/beyondi/understanding-hyperledger-explorer-setup-via-docker-6af845fcb82e
Hello, I have gone through the article and I am facing one strange issue in my setup, In my network, there are 2 channels, but my explorer only lists 1 channel in the dashboard drop down. As my fabric is running on v1.3, so I am using tag 0.3.8 of explorer, and have followed the instructions mentioned in its readme file, but not able to figure out why second channel is not visible although I am able to do transactions in that channel from an SDK app and have also configured service discovery variables in my peer container. Can you please suggest what can be the issue here ?
Hi, I had just created Jira (BE-661 & BE-662) requesting for new features. Please can you let me know how these are considered and included into the tool - any project plans (or) roadmap ?
On first what I could say is that you need to check your connection-profile file and define one more channel in channels properties (like we have bowchannel) where peer will be defined peer from peers property.
Maybe I am not 100% right because I don't have time to try that right now but based on what I see, that seems logic step to try.
I have gone through the readme file and it is mentioned that channel should automatically picked through service discovery , although I even tried mentioning my second channel in the connection-profile, but still it was not visible.
@KristijanGlibo , thank you for your article, would you like to contribute to HLExplorer in creating a tutorial, similar to HLFabric tutorial?
:thumbsup:
hi, these jira's needs to be reviewed, and if there are resources we can assign, as of now only 2.5 resources are allocated to the project, and we are working towards graduating explorer from the incubation, but if you want to contribute on those jira's you're more than welcomed.
Hi, me and my team would like to contribute to the tool. Pls could you point us on how to get started? (Source code, any design docs, technology used, how to fork and merge back etc... )
Hi, is there a setting for explorer to work behind a reverse proxy?

can you tell me what changes should i make in config.json
are you running on same machine explorer and fabric?
yes
it works fine for mychannel
are you using some samples, or your custom fabric network?

Clone git repository of hyperledger explorer form this link git clone https://github.com/hyperledger/blockchain-explorer.git and I am using fabric version 1.1 and node version v8.16.0 which is compatible.
Not able to figure out where I am going wrong :thinking:
did you $git checkout v0.3.5.1 ?
1) you need to add the IP address of the explorer to the remote fabric network to allow connectionm
2) copy crypto somewhere on your machine where you run explorer
are you able to make connection to remote fabric and see the channel in Explorer? if this is the case you need to enable discovery service , see here how to https://hyperledger-fabric.readthedocs.io/en/release-1.4/gossip.html

everything is on the same machine, I'm not using the explorer docker image since I'm using start.sh
console-2019-06-21.log
and the app.log file?
app.log
was uploading it
it's both logs
which browser do you use?
firefox 67.0.3 (64-bit)
FF is fine, can you hard reload with cache clearing ?
logss looks good to me
doesn't change anything
y, no flashing red error, that's why I'm a bit lost
can you post the logs/db/db.log ?
one is it on AWS?
everything is on local
one more*
db.log
db logs look good
i just tried FF, works fine
can you try in private mode?
are you behind the proxy?
tried in private and checked that I don't have proxy, did not change a thing
can you open FF in developer mode, and see the console ?
I have the console, that's how I saw it's a 404 error
ah no sorry, console doesn't print anything
but I checked the requests in it, that's where I found the 404
the GET request
let do some curl request
sure
can you try this url http://localhost:8080/api-docs/
this one works
do you have any plugins installed that could prevent for accessing?
can you disable all the plugins in FF?
I disabled ublock and noscript before testing
very interesting case
at leat now I can play with api-docs to send requests and check the logs
at least now I can play with api-docs to send requests and check the logs
can you try with Gchrome?
you can't , you need the jwt token
same error
and chromium is a fresh install, no plugins whatsoever
i think your browser is pretty loaded with setting
I used chromium once or twice as I said, fresh install
i see
do you have any settings in hosts file?
which one?
let's change the port in blockchain-explorer/appconfig.json, and restart the app
change to 8083
still the Cannot GET /
From what I can tell, logs look the same
something is blocking
can you try to use the tag v0.3.9.4 ?
sure, 10in and I'll keep you updated
sure, 10min and I'll keep you updated
thanks
I cloned a clean repo and switched to v0.3.9.4, still the same error
could be some permission problem ?
doubtful, not sure what to try, I threw a sudo in the start.sh for the node command, didn't change anything either
but I might have some npm issues, I never finished the tests for the build, because the folder "client" doesn't exist (https://github.com/hyperledger/blockchain-explorer#100-build-hyperledger-explorer---- )
imma try a fresh first-network too, just in case
do ./main.sh install from the project root
won't work without sudo, my npm is kinda messy, I usually have to sudo npm, delete the node modules and then I can npm without sudo
clean first-network, still the same error
do not run as root, do this $ mkdir -p hlexplorer && chmod -R 775 hlexplorer && cd hlexplorer
then git clone
a good practice, do not run as root, as log you're not installing a package
i mean ubuntu software
not true, but for npm it is y
ok
imma try that in a sec
sure
as I feared, doesn"t change the fact that I cannot do ./main.sh install without having permission denied
then you need to $su
I'll try again next week after unmessing npm
switch user
which node version do you use?
8.16.0
ok
correct otherwise the api wouldn't work
good luck, keep posted
ran everything as root, now it works, so it definitely is npm :) will clean it up later, thank you very much and have a good weekend
ok
For anyone following the convo: problem was that my build wasn't correct, due to my npm being messed up. Apparently can lead to the Explorer "kinda working" but only displaying "Cannot GET /" (which is a typical node error according to google)
would you be able to contribute to hl explorer, i see you have good skills
any contribution, UI, node backend
I'm more of a C guy tbh x) I just had to setup an HLF network and I figured I'd check explorer for a nice UI
but thanks for the offer :)
sure, no problem, you must be good with .sh scripting ?

Nice contribution! Can you give us more detail to recreate the problem or raise a new JIRA? @periodic
@nekia To reproduce it just stop explorer-db docker container (stop db) wait for connection error in explorer container and start explorer-db again. But it seems that some other error codes have to be supported (i.e. ECONNRESET). Anyway I'll try to create issue in JIRA...
Thanks! If you have any unclear, please let us know. I'll also try to reproduce it.

What was the problem with the nodes? (did you enable discovery service?) , need more info on "However, the issue of the orderer information continuing to refresh in the log has not been resolved."

Hi everybody. I've tried to use explorer (its docker images), but faced with the connection problem after some time its activity. I've figured out that the problem is the following: explorer doesn't reconnect to db (postgreSQL) on losing connection.

@vanitas92 Seem you are using scheme of network profile config (https://github.com/hyperledger/blockchain-explorer/blob/master/app/platform/fabric/connection-profile/first-network.json) instead of fabric platform config (https://github.com/hyperledger/blockchain-explorer/blob/master/app/platform/fabric/config.json)
yes, we are using connection profile, with latest gateway of fabric-network
did you rebuild after $git pull? you can use $main.sh install from the root of the project
please configure as per instructions , https://github.com/hyperledger/blockchain-explorer#70-configure-hyperledger-fabric----

The log keeps refreshing, and after a few hours the service will hang up.
is it on your PC, maybe the OS is suspending the service?
no is doesn't
explorer was not tested with etcdraft, and is not supported
thank you we will look into this issue.
just saw your message that it is not supported Etcdraft as consensus, and i am using it, so maybe not going to work anyway..

Hello everyone! Good Morning!
I'm used to develop in Hyperledger Fabric, and in the last days, I'm started to read about Hyperledger Explorer and how to connect it to my Fabric application.
In the "Getting started", I'm having a problem with ./createdb.sh.
I already installed the prerequisites (Nodejs 8.12.0, PostgreSQL 11.3 and jq 1.6).
But when I run the createdb.sh, a error is happening when a password is solicited to me for user "my_user"
The error is:
`psql: FATAL: password authentication failed for user "my_user".`
When I run other commands usig "sudo ...", my password authentication works perfectly.
Any thoughts about how I should proceed in this case?
Thanks!
You might need to provide permissions to your db directory. From blockchain-explorer/app/persistence/fabric/postgreSQL run: `chmod -R 775 db/`

Hello, I've just started with HL Explorer, I have followed the tutorials but I did not managed to get the explorer running. I have a fabric network running (which has been tested and it works smoothly), I have created the database and tables using the `createdb.sh` and I have the connection profile setup correctly following the example fabric_example (connection profile). When I use the ./start script I only see the following:

it stops there

I have gone through the troubleshooting section but I don't find anything that helps
Thank you for using explorer! Unfortunately I have no idea what's happening. Did you try it with fabric-samples/first-network environment to see explorer works correctly? @Suarez20
Thanks!
@FernandaSartori did it solve your problem?
Yes. That may work.
In fact, my problem was referring to the postgres user. I installed postgres separately from the other requirements, and in the installation, a user for postgres was created in root of my computer with a random password. I delete this user that was created, delete the postgres installation and then install postgres using the homebrew.
glad it worked

[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=b54oKbrwe7CmgZfHx) @fsoares I think you need to add definition of TZ environment variable to your docker compose file. Ex. TZ='Asia/Kolkata'
https://www.gnu.org/software/libc/manual/html_node/TZ-Variable.html
FIXED: The problem was in the connection profile, I had to change those `localhost` in the urls to the names , like ca.example.com, peer0.org1.example.com and orderer.example.com

no, you can use the images from docker hub
We use both gerrit and github, gerrit is for the review, and code approval
admin user/password is used to connect to fabric-ca server, but if you're not using fabric-ca server, you do not need user/password
You can set a user/password before the home page of Explorer. This can be set on the connection profile under `client.adminUser` and `client.adminPassword`
:thumbsup:
Explorer will need to build a user/roles model for the authentication, there is not yet a design for that, if any of you would like to contribute with a design of such, we welcome you

sure, thank you
As long as I'm looking over the current status on my local fabric 1.4.1 raft environment, explorer seems to be working fine without any errors.
great, so no changes required to support raft?
I think, it depends on requirement.
Do we need to add all orderer nodes to "NETWORK" view or "peer" list on "DASHBOARD" view?
If we don't need any GUI changes, yes, no change seems to be required so far.
Yes, i believe so, I wouldn't be able to do much on HLExplorer, working on internal project, but i'll answer emails, and question
I think, just the backend, db query and insert may required
https://jira.hyperledger.org/browse/BE-681?focusedCommentId=62003&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-62003
Each orderer node information discovered has already been inserted to peer table as we expect.
as I recall i think the query needs to be change for the retrieval?
I'm not sure. We need to look through it more closer.
sure, thanks

If you have already completed the setup of your fabric network with enabling mutual TLS, you don't need any additional setup on blockchain explorer. fabric-sdk will handle it properly by using identity in your wallet. Before I've tried it on fabric-samples/first-network environment. Please refer the above comment in detail. @soumyanayak
Thanks Nekia will try it out

EAI_AGAIN means [A temporary failure in name resolution occurred](https://docs.microsoft.com/en-au/windows/win32/api/ws2tcpip/nf-ws2tcpip-getaddrinfo#return-value).
As mentioned on the article ( and also README.md ), you need to align the network that explorer belongs to the one that fabric network belong.
You should be able to see peer containers and explorer containers when inspecting the network ( `docker network inspect {network_name}` ).
Hi Nekia,
in my fabric network set up the -- network_mode is used as "host". i havent specified any network name in any of the orderer or peer containers
so the same network_mode as host , i used in the explorer docker-compose.yaml file
I'm not sure host network mode of docker, I guess the hostname is not resolved any more on your environment unless adding ip/hostname definitions on your host OS.
For test purpose, if you change these host name to `127.0.0.1`, what's happened?

configured in blockchain-explorer
whereas when i am connecting from node sdk Gateway.js with the similar details and configuration in the connection.yaml file i am able to connect and carry out the operations from chaincode installed on peers...
Your EAI_AGAIN error occurred on the connection between explorer container and explorer db container. So connection profile has nothing to do with this error.
When using host network, both explorer and explorer db containers run as 127.0.0.1:8090( or :5432 ). I have never tried before, but I think you need to specify DB address with 127.0.0.1, not hostname(ex. explorerdb.example.com) in your docker-compose.yaml.
ok Nekia will try that and update you
Thanks Nekia as you mentioned i modified and it worked..
so let me know if you are able to achieve the mutual TLS thing .. like in which class we have to set up the client certififcates .. for Node SDK i was doing it in gateway.class
That's great :thumbsup:
https://fabric-sdk-node.github.io/release-1.4/module-fabric-network.Gateway.html#~GatewayOptions
all you
all you have to do is configuring clientTlsIdentity in
all you have to do is configuring clientTlsIdentity in GatewayOptions when
all you have to do is configuring clientTlsIdentity in GatewayOptions when calling gateway.connect(), I think.
Please ask to fabric-sdk-node folks about the detail.
In the current Explorer implementation, same identity is always used for GatewayOptions.identity and GatewayOptions.clientTlsIdentity.
ya i had done it from node SDK but in the blockchain explorer folder where this gateway.class is present?
if (sslEnabled) {
const options = {
key: fs.readFileSync(sslPath + '/privatekey.pem').toString(),
cert: fs.readFileSync(sslPath + '/certificate.pem').toString()
};
server = https.createServer(options, explorer.getApp());
} else {
server = http.createServer(explorer.getApp());
}
i found the above code in main.js that is invoked.. so is it in the If part we have to give the paths for the private key and certificate
for the mutual TLS?
and in appconfig.json we have to mention the sslenabled as true .
This is what we have to do?
That is the configuration of setup for accessing Explorer frontend via https.
I'm a little bit confused. I'm not sure what you want to do. Can you issue a JIRA to describe what you want and what is issue?

Does explorer support fabric 1.4.2 ?
We're working
We're working on it on [cii-badge branch](https://github.com/hyperledger/blockchain-explorer/tree/cii-badge). Explorer works fine so far without any issues. It'll be included the next release.
ikan8 - i had made the explorer work with 1.4.2 only .. as of now i have achieved in one way TLS
ia m trying now with mutual TLS once done that will update

changed localhost to ip address of my server
try once with 127.0.0.1 instead of localhost
ok
thats not working...
i tried with the docker and set up and i am able to achieve it
https://medium.com/beyondi/understanding-hyperledger-explorer-setup-via-docker-6af845fcb82e
i guess il have to replace localhost with my servers ip address coz m running network on server and running explorer on local
You can follow the link
locally i have run it..
i was deploying it on server
yeah if they are all different servers then you have to give the IPs
yup...it shows login scrren on browser but cant log in
login with admin/adminpw
its not able to connect to db
Can you provide more detail of your environment? Which branch, tag of explorer are you using? Which verion of fabric? You can also create a new JIRA to discuss more closely. @sanket1211

hi..i used cii-badge branch still facing the same issue
i think its the db issue
after \d it doesnt show any tables..
Did you run createdb.sh?
yes
Can you see fabricexplorer database after \l?
yes
Did you see any errors when running createdb.sh?
Please run createdb.sh again.

looks good. And then run `sudo -u postgres psql -d fabricexplorer -c '\dt'`

yes
m trying to host from server...
i can see the login screen but when i enter credentials..it gives error as invalid user,password
Did you set enableAuthentication in your connection profile to `true`? Currently there is no authentication except validating id/password specified in the profile.
any other things to be taken care of while doing hosting??
enableAuthentication is true
still the same error of credentials..
after syncstart...it doesnt work..i had to start.sh
for log in screen to load
:thumbsup:
> any other things to be taken care of while doing hosting??
I think it depends on your requirements.
when i run npm test -- -u --coverage...1 test fails...that might be the reason??
Sorry, I misunderstood that it did work. If you can provide more detail on JIRA BE-691, we'll be able to do more analyze for this issue.
Ex. Attaching connection profile you're using. Describing steps to reproduce this issue and the kind of fabric network you use (fabric-samples/first-network? or your own custom network ?) etc.
As far as using explorer enabled authentication ( with fabric-samples/first-network, I can login successfully without any errors.
As far as using explorer enabled authentication (id/pass = admin/adminpw) with fabric-samples/first-network, I can login successfully without any errors.

I guess you enabled authentication in your connection profile. It depends on your fabric-ca server configuration. But, unfortunately, as I mentioned [the post](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=5afb1af1-e408-490f-bc0b-3bebe6610d11) a few days ago, support of fabric ca is not fully implemented.

Is there anywhere to read about how to write a good connection profile for explorer ?
Unfortunately,
Unfortunately, recent a few weeks, I didn't have much time to do any works for Explorer. But I seem to be able to have some time to handle one of them this coming week!
Did you see tREADME.md]
Did you see [README.md](https://github.com/hyperledger/blockchain-explorer/blob/master/README.md#60-fabric-network-setup----)? CORE_PEER_GOSSIP_BOOTSTRAP and CORE_PEER_GOSSIP_EXTERNALENDPOINT are important because we're using discovery service to detect peers.
Yeah I did so, but my Explorer still sees only one peer...
What kind of fabric network are you using? fabric-samples/first-network or your own network?
Anchor peer settings are also important for gossip (discovery service). If you are using first-network (byfn.sh), it does configure it by default.
I'm using my own network
By using discover cli, you can see whether discovery service is detecting all peers as expected or not.

Hi, I've got "[ERROR] FabricUtils - Server hostname is not defined default peer [peer0.org1.example.com] in configuration" in the app.log file, what does it means?. I have the release3.8 explorer

@nekia Thanks. Just for you know.. I've changed to 3.9.5 but I've got the "Error: Failed to connect before the deadline URL:grpcs://localhost:7051"
The problem was the conf file
In the app/platform/fabric/connection-profile/first-network.json that come by default in the peers : {peer0.org1.example.com {}} key
have a "grpcsOptions" instead of "grpcOptions". I've changed it and it works fine.
It's weird. There is no such a option for connection profile.

Do you see any errors in the docker logs of the explorer and explorerdb container?
i dont see the other container running
explorer.mynetwork.com
@soumyanayak There are no errors in docker logs.
Can you post me the complete logs of the two containers -- ```explorerdb.mynetwork.com``` and ```explorer.mynetwork.com```
both the files you can zip and post here
Ideally, explorer.mynetwork.com container runs with docker-compose.yaml. But in our scenario, it's not running
PFA explorerdb.mynetwork.com logs
explorerdb.mynetwork.com.zip
so that container should also run -- explorer.mynetwork.com there is some issue it exited aand that is why youa re not able to see the application
explorer.mynetwork.com.zip
Yes, you are correct it exited 3 hours back. Attached logs for the same
Error : Failed to connect client peer, please check the configuration and peer status
this is the error
please check that its not connecting to the peer -- the configuration JSON or YAMl file
and i had tried with one way TLS
@soumyanayak : Do you have any docs for the same?
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=AAWw9iiatczCaYDB4)
Explorer_SetUp.docx
try this you can have your own IP addresses/DNS names .
Ok @soumyanayak but in our setup below cert is not generated
"/tmp/crypto/org1/peer1/tls-msp/tlscacerts/tls-172-23-155-113-7052.pem"
or similar to this
Even in DOcker logs we saw this error:
{ Error: ENOENT: no such file or directory, open '/tmp/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/signcerts/Admin@org1.example.com-cert.pem'
But Fabric Multi-Node network is running fine
you can read my doc i have mentioned about this -- certififcate mapping i have done as per my certififcates folder in the docker compose
Ok... I will check and get back to you
Thanks much @soumyanayak
Hi,
We are doing Hyperledger Explorer setup with Fabric in a single machine.
PFB URL we are following for setup:
https://medium.com/@thanawitsupinnapong/setting-up-hyperledger-explorer-on-fabric-5f1f7cda73b3
Fabric Configurations:
======================
ORG1 --> Peer0ORG1 and Peer1ORG1
ORG2 --> Peer0ORG2 and Peer1ORG2
We achive the setup successfully and explorer console is accessible.
Even Fabcar chaincode is working fine on it. But we are not able to see transactions updating on all the Organisations and peers via Explorer UI.
Could you please suggest is it a Bug in explorer or we need to alter any configurations so all transactions are visible for all the peers.
Has joined the channel.
hi! I want to start developing hyperledger explorer functionalities, is it explained how to start a dev environment? because it tries to connect to a network, thanks!
Hi again @nekia ! I checked for the dicovery service and the peer's environment variables and everything is allrigth. Do you think of something it could be ??
Thank you for updating.
It means that you could see all peers which is expected to be detected via discover command? @carlosalca
You can also raise jira and provide more detail of your environment there to discuss more closer your issue.
Hi all, I try to run blockcchain-explorer on my own network(org5, orderer5) but I count this error.
I guess low version has a orderer config info in connection-profile/honeybee-network.json. but I can't find on the repository example(first-network.json, fabcar.json) where can I fix this error or how could I solve this error? Thank you in advance.

I think, it's good option that you try to use explorer on first-network first. You need to check the following
* You can see `Error: listen EADDRINUSE :::8080`. Is there any explorer that has already been running?
* If first-network is running on the same machine on which you're trying to start explorer, you need to use `start.sh` or define `export DISCOVERY_AS_LOCALHOST=true` for mapping each URL of nodes to localhost.

Please check the path of your certificate path as its clearly throwing the error the directory not found
yeah me giving the correct directory still me find this error
youa re using docker based or native based ?
Screenshot from 2019-10-09 15-55-39.png
yeah me using docker based
Screenshot from 2019-10-09 17-42-07.png
Can you please post your docker-compose and config.json once here
docker-compose.yaml.zip
data.json.zip
Screenshot from 2019-10-09 18-06-06.png
can you tell me whats the content in the path -- *./examples/net1/crypto*
crytpo file is null here
in tmp folder i have placed the crytp-config folder
because for certifficates mapping i could see the mapping
- ./examples/net1/crypto:/tmp/crypto
Screenshot from 2019-10-09 17-42-07.png
under crypto folder in your local the certificates should be there with the folders as peerOrganizations and ordererOrganizations
yeah in crypto folder there is the
yeah same
yeah i have located it
what you do is in the keystore folder change that long value _sk to key.pem
and map the same in your json file
but how
i have to create the key.pem
for eg like instead of this path -- /tmp/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/keystore/16792f27b4fa8a855fe8bd74be9de3fef0c8b0f70e37344793a7031630b11345_sk -- map it as /tmp/crypto/peerOrganizations/org1.example.com/users/Admin@org1.example.com/msp/keystore/key.pem
rename that file to key.pem
okh
Screenshot from 2019-10-09 18-19-39.png
yeah
i renamed the file herer
Screenshot from 2019-10-09 18-21-28.png
expand your crypto folder
????
under the crypto folder its mapped right
yeah
i renamed the file there also
in your docker compose the mapping that you have done is
- *./examples/net1/crypto*:/tmp/crypto
yeah
left side is the path in your local and right is inside your docker conatiner
so its not in the local path under temp folder
but above the tmp there is a folder crypto
inside that folder all your files should be there instead of tmp/crypto
oh that means in left i have to replace peer order crypto file
in ./example/net1/crypto
yes inside this folder you need to have all the contents which youa re currently having in ./tmp/crypto
folder means ./example/net1/crypto
in that folder
???
yes
right
no need to change in json file
???
not required
because this one is your local path *./example/net1/crypto* what ever you keep in here will be reflected inside the docker conatiner path - */tmp/crypto*

Thanks much @nekia for the link. But our concern is more towards multi-Organisation setup
With Single Org along with one peer we already achieved explorer setup . But in muti-org setup transaction are not updating in both organisations simultaneously(We could see only first Organisation is updating i.e. ORG1 instead of ORG2 or ORG3)
Please suggest monitoring tools which supports Hyperledger Fabric framework (Instead of hyperledger Explorer as we are facing issues in multi-org or multi-node setup)
What is the issue you are facing @nakulgr13
we are able to do the set up using explorer for multi org
We are able to setup Explorer with Multi-org but can't see transaction handling in ORG2 (By Default all request are handling by ORG1 only)
Note: We are talking about single Node mult-org setup now instead of multi-node setup with multi-org
Hi! Both of you are able to see more than one peer ?
yes i am able to see all the peers
even single node multi org also it should be working . As @simran did it and can help you on that

Hi @simran
As suggested by @soumyanayak please assist us to resolve multi-org and multi-node explorer setup issues.
We already posted our issues.
Please let us know for further details
i did only siingle org setup me also doing the same thing nakul seeting up a multiorg for multinode in the explorer network
Ok
Please let us know once you successfully achieve multi-org or multi-node setup.
with Explorer
yeah nakul i will let you know @nakulgr13
yeah @simran has expertise in the hyperledger explorer she can help you will all your errors
ok @Shubham-koli

Hello Team,
has anyone set up the multi node with multi org on the hyperledger explorer

Hi, is the explorer compatible with Sawtooth? I tried to run https://github.com/hyperledger/sawtooth-explorer and I am getting many errors while issuing docker-compose, more specifically I get `ERROR: Service 'ng-server' failed to build: The command '/bin/sh -c npm run build' returned a non-zero code: 1

As you have installed postgres and the db is running fine try to login into the postgres db
psql -d fabricexplorer-U postgres-p

yes, i have installed it and below is the output:

I tried to change the connection string in Pgservices.js to
``` const connectionString = "postgres://postgres:password@localhost:5433/fabricexplorer"; ``` and even it is not workring.
then changed it back to original one.
@soumyanayak finally I fixed it. postgresql is listening on `5433` and In the explorerconfig.json it was `5432`
Hi @soumyanayak , now I'm trying to use docker-compose and facing some issue.
Hi @soumyanayak , now I'm trying to use docker-compose and I'm facing some issue.
Psingh - Tue Oct 15 2019 15:40:49 GMT+0530 (India Standard Time).txt
in the error its throwing the below where its not able to find the PEM file --
problem reading the PEM file :: Error: ENOENT: no such file or directory, open '/home/alpha/GoWorkspace/src/github.com/MultiOrgs/networks/crypto-config/peerOrganizations/org1.example.com/ca/ca.org1.example.com-cert.pem'

Please check the paths mapped in volumes section in docker-compose
and also once in the config.json file
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=XnLgBSbes3QwgzQPR) CA path isn't there in the volumes. I thought it's going to fetch every detail from config.json itself.
Do I have to add the CA path in the docker volumes too?
this is the docker config:
```
explorer.mynetwork.com: image: hyperledger/explorer:latest container_name: explorer.mynetwork.com hostname: explorer.mynetwork.com environment: - DATABASE_HOST=explorerdb.mynetwork.com - DATABASE_USERNAME=hppoc - DATABASE_PASSWD=password # - DATABASE_PORT=5433 - DISCOVERY_AS_LOCALHOST=false volumes: - ./examples/net1/config.json:/opt/explorer/app/platform/fabric/config.json - ./examples/net1/connection-profile:/opt/explorer/app/platform/fabric/connection-profile - ./examples/net1/crypto:/tmp/crypto - walletstore:/opt/wallet command: sh -c "sleep 16&& node /opt/explorer/main.js && tail -f /dev/null" ports: - 8090:8080 networks: - byfn
```
./examples/net1/crypto:/tmp/crypto
this is the crypto mapping
so map this correctly from your local file system the certififcates folder path
and also map accordingly in the config json also
fixed the `cert not found` issue and now I'm getting some `BASEWALLET` related issue
```
2019-10-15T11:02:21.025Z - error: [BaseWallet]: setUserContext: identity 'admin' isn't enrolled, or loaded
explorer.mynetwork.com | Error: identity 'admin' isn't enrolled, or loaded explorer.mynetwork.com | at FileSystemWallet.setUserContext (/opt/explorer/node_modules/fabric-network/lib/impl/wallet/basewallet.js:56:10) explorer.mynetwork.com | at
where is this `walletstore` created?
this walletstore is created a spart of docker volumes managed by docker
in the config json you have th client section
in the config json you have the client section
"client": {
"tlsEnable": true,
"adminUser": "admin",
"adminPassword": "adminpw",
"enableAuthentication": false,
"organization": "Org1",
"connection": {
"timeout": {
"peer": {
"endorser": "300"
},
"orderer": "300"
}
}
}
so what am I suppose to do now? explorer docker config is strange when compared to fabric docker
please share your config.json file once
ok
its simply you have to map the files in docker volumes and that's it

Make sure to set the environment variables CORE_PEER_GOSSIP_BOOTSTRAP and CORE_PEER_GOSSIP_EXTERNALENDPOINT for each peer in the docker-compose.yaml file. These settings enable the Fabric discovery service, which is used by Hyperledger Explorer to discover the network topology.

I have one more query. Can I setup a separate explorer for each organization? Right now anyone can see the the txn of any Organization
@nekia any thoughts on this
In the current explorer, you can see only txn related to the organization you specified in the connection profile. The txn generated on a channel which the organization doesn't belong will be invisible.

Hi everyone. I've installed and configured Hyperledger Explorer into a already created Fabric instance with Composer. Right now, when I try to connect to the Hyperledger Explorer client page, the page turns all white and I get this error on the console "TypeError: "t is null"" at operations.js:41:11. I've searched everywhere and here and I can't find anyone with the same error. Can anyone help me with this?
Can you post your example.json once here

Ok, so I tried again going through this method. Right now I cant connect to :8090, keep getting "Unable to Connect". I can connect to :9090 where prometheus is hosted, so the containers must be running. How can I debug this issue? Thanks
Through netstat I can see that the port is open and the docker-proxy is running there
You can see more information via the following command:
```
docker logs explorer.mynetwork.com
```
Note: There is 16sec delay before getting explorer service ready when using docker-compose env.
I've managed to get it to work, with a mix of tweaking with docker-compose.yaml e config.js based on info gathered from docker logs. Also, I haven't passed /crypto to examples... Thanks for the help!

Can somebody explain me how the "Register User" function of Hyperledger Explorer works ? Does Affiliation stands for Organization ? Is it designed to create a new user on the network ( including public/priv keys etc ) ? On my side it doesn't work ...
I asked the same question a few weeks ago, the answer is that the "Register User" function is not implemented yet

Could you tell me what version you are using ? I am a bit confuse because the register button is available and opening a dedicated screen asking for relevant information so ...
I have the last version available and that also appears on my deployment but I was told it doesn't work
Register user works with fabric-ca configured network, and it should add the user to the network, try to configure with balance transfer sample to see it working, "Affiliation" can be found in your fabric-ca config, see here https://hyperledger-fabric-ca.readthedocs.io/en/release-1.4/serverconfig.html
And the sad news are, that is is not fully implemented, we are very loa in resources, 1 man, please if you guys what to make any contribution, please do not hesitate to ask.

Can some one please help me with this error in explorer. I could able to access explorer when blocks are less i.e around 300000, but when number of blocks are increasing i.e more than 800000 I am getting this error "Please verify your network configuration, database configuration and try again". I tried to increase explorer db and exlorer memory but still facing same issue.
is this in a docker environment?
yes, it is containerized, using kubernetes to manage containers
@nfrunza , thanks for responding, yes, it is in docker, using kubernetes to manage containers
is there any chance you try in a local environment? this could give you the hints if you need to increase your docker resources
@nfrunza , we are facing this issue in production and dev environment, our environment is setup in AWS with Kubernetes on EC2 instances
how big is a record?
how big is a record in KB? which version of the explorer do you use in production ?
what type of data do you store, i mean any images, media etc?
In production we are using explore 0.3.9.3v, data is text. I could see transactions in explorer are around 2million
is it working or you still have problems?
i would suggest to run sync as standalone job, and you can have more than one sync process read here https://github.com/hyperledger/blockchain-explorer#110-run-hyperledger-explorer----

Hi all, I am discovering hyperledger-explorer and have some troubles understanding what it can achieve.
Say I have a network with 2 orgs : org1 and org2 which are in a same channel. *I am part of org1*, and so have access to my org1 “adminPrivateKey” only which I put in the hyperledger-explorer connection-profile.
If I deploy an hyperledger-explorer dashboard:
- will I be able to see my ordering peer without hard-coding it in the connection-profile (I see my two peers thanks to gossiping, but I doesn't seem to exist a similar thing for the ordering peer)?
- will I be able to see peers added by org2 ?
- will I be able to see a newly created channel in which I’m in without modifying my connection-profile ?

do I have to change "type" = "local" to "host"
if you want to run the sync standalone?
Also, creating separate AWS postgreSQL db and providing host information in above "host" value will work? I am trying to understand whether separate external postgreSQL db works or not.

Hello there ! I am using HL Explorer in Docker and the log files under `logs/app` are filling very quicly, to the point that the log file of one day is over 5 GB. The log files are actually filled with the same `SyncServices - Block synch in process for >> first-network_mychannel` line, repeated many thousand times per second. I identified it comes from the `app/platform/fabric/sync/SyncService.js` file (here https://github.com/hyperledger/blockchain-explorer/blob/master/app/platform/fabric/sync/SyncService.js#L350) with a call to logger.info(). As the logging level is not set in the file (using logger.setLevel) I don't think the level can be changed by passing an env variable. So I basically have two questions:
- is it normal to have this function called so often that it prints the log many thousand times per second, or is there something wrong on my side?
- is there a way to change the logging level, other than building my custom image with a `logger.setLevel` line added to the SyncService.js file?
Thank you !
i think we need to identify the value of the infor that is collected, and added to the logs, second, if that is really needed, maybe we should add within a time interval, let say every 1-3 minute print such info.
I'll see if I can reproduce it. I don't think it's normal.

did you run the $blockchain-explorer/app/persistence/fabric/postgreSQL/db/createdb.sh script? , please make sure you have follow the steps in https://github.com/hyperledger/blockchain-explorer#Database-Setup
yes i did
able to see explorer db and with tables
which branch, tag do you juse?
can you use the latest tag?
its release-3.9
yes iam able to use latest tag
is it working for you now? these are the latest tags v0.3.9.5
v1.0.0-rc1
haven't tried with v0.3.9.5 v1.0.0-rc1
now using v0.3.9 only
when switching from one tag to another , you need to rerun /$blockchain-explorer/app/persistence/fabric/postgreSQL/db/createdb.sh

Is there any documentation on the code for Fabric Explorer's UI?
@tengc unfortunately we don't have any
@nfrunza Is Explorer compatible with HLF v1.4.3?
@metadata Yeah it is
I am running it
There is a basic readme file which is enough to host the UI
thanks @Paradox-AT
No problem
@Paradox-AT @metadata can you contribute to HLExplorer?
I see, I was hoping for an explanation on the client code. Thanks for the response.
Dumb question, but is there anyway to set names for peer nodes? I've deployed a Fabric network using IP addresses for most the address environmental variables instead of hostnames. In the network tab for the UI, the name of the peers end up being IP addresses. This becomes an issue if multiple peers have the same IP address, but are connected via different ports. Hoping there's parameter I can add to the docker compose files to resolve this.
@tengc very good point, explorer doesn't have such ability, can you ask in https://chat.hyperledger.org/channel/fabric-questions
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=6eHA3pAFcGp7Hnvb3) AFAIK u can't if the network is up and running. But if u are building from the scratch then u can add `1.2.3.4 peer0.org1.com ` in the `/etc/hosts` file.
In the docker-compose we use `extra_hosts` that will create the same mapping in the container's `/etc/hosts` file.
A silly answer is try `peer0.org1.com 1.2.3.4` in the `/etc/hosts` file. I never tried it and even not sure if it is going to work or either we can add this type of mapping in the `/etc/hosts` file.
@metadata let me kow if it works
Sorry, I am not that good with developing UI

dude i not think that is a proxy problem =(
@herculan0 fixed it by following I fix it : https://serverfault.com/questions/406606/postgres-error-message-fatal-ident-authentication-failed-for-user
There is no Ident server running on the machine you're trying to connect from. Test this by trying to connect to it on port 113. If that fails, install an Ident server (eg, sudo apt-get install oidentd).
Maybe you actually want to connect with a password, not Ident. Edit the pg_hba.conf file
host all all 127.0.0.1/32 ident
to
host all all 127.0.0.1/32 md5
and it works!

Hi! I tested the explorer on this network setup:
3 Org (OrgA, OrgB, OrgC)
2 Channel (ChannelAB, ChannelAC)
Spinned up an explorer with 2 network-profile:
1. OrgA Peer0 ChannelAC
2. OrgB Peer0 ChannelAB
Findings:
1. Login through Org A network profile => I can see both channels (AC, AB) - cool auto discovery through Orderer node
2. Login through Org B network profile => I can see both channels (AC, AB) - Something is wrong, i shouldnt see channel AC
Can someone please tell me if this is a bug or something wrong with my config?

One network per instance of explorer
what do you mean?
what do you mean? There is only one network in this scenario
Hello everyone, is it mandatory to specify a channel in the connection-profile ?
Leaving the `"channels": {}` empty gives me a `Channel not found for name undefined` error.
i see two connection profiles : "network-configs": {
"organization-one": {
"name": "organizationOne",
"profile": "./connection-profile/organization-one.json"
},
"organization-two": {
"name": "organizationTwo",
"profile": "./connection-profile/organization-two.json"
}
},
"license": "Apache-2.0"
}
default channel needs to use the discovery service , see https://fabric-sdk-node.github.io/tutorial-discovery.html
default channel name is a must
Actually, I configured the channel with `configtxgen` and created it with `peer channel create`. I am unable to find any reference to a discovery kind-of option in the docs. All I did yet related to the discovery service was to set the `CORE_PEER_GOSSIP_EXTERNALENDPOINT` env variable for my peer.
I never used the fabric sdk for nodejs, so I'll give it a look, thanks.
@rquera , sure, take your time
so one connection profile per explorer?

hello people, new to explorer, can anyone help me how to connect a fabric network(first-network) with explorer using docker . I tried to follow https://medium.com/beyondi/understanding-hyperledger-explorer-setup-via-docker-6af845fcb82e but I don't get (config.json connection profile and keychain folder )which files need to be configured

@chaitanya5 @nekia should be able to help you
It's nothing to do with access to the postgres db. It's for https access of explorer itself.
Can you see the database via psql cli?
```
$ sudo -u postgres psql -d fabricexplorer -c '\dt'

You need to do the following step.
```
This file contains the certificates and artefacts of the blockchain network that we want to put Hyperldger Explorer. In our case, we copied them from our blockchain network to examples/net1/keychain folder.
```
yes i can see
Do you mean that you can see fabricexplorer database from the machine where you are trying to launch explorer to 132.145.70.5+5432 ?
Do you mean that you can see fabricexplorer database from the machine where you are trying to launch explorer to 132.145.70.5:5432 ?
Yes
Are you running postgreSQL DB on the machine where explorer is running? If so, please change postgreSQL host address to `127.0.0.1` in `app/explorerconfig.json`.

I use blockchain-explorer v3.5.1 with fabric 1.1. and faced with the problems:
1, the explorer deployed with five peers in one machine, then i found, the web browser often can't open the dashboard via ip:port
it often shows"Please verify your network configuration, database configuration and try again".
sometimes it is ok,but it is very slow. if the dashboard web can be reached, the data is also ok
2,how the backend push the block and tx data, from the order or the peer? will the dashboard be reached only the data sync finished?
the dashboard showes the data only from the database, will it get data from fabric for show?
3,so how to determine the problem, i changed the loglevel and checked the log, but got no clue
did you build, ./main.sh clean && ./main.sh install ?
please follow up https://github.com/hyperledger/blockchain-explorer/blob/master/README.md , we did not publish that article
I'm sorry for the late reply
I am good with go, javascript, java
I sure can contribute small things even on the UI but I prefer to work on the backend
@Paradox-AT great, thank you for the reply, please take a look at our jira's .https://jira.hyperledger.org/secure/RapidBoard.jspa?rapidView=155&projectKey=BE&view=planning&selectedIssue=BE-720 and see what you want to work on, we use github, also see how to contribute, https://github.com/hyperledger/blockchain-explorer/blob/master/CONTRIBUTING.md#code-contribution-and-submitting-your-fix

Hi @nfrunza, I've got a general question on hyperledger explorer. After following the installation routine (prometheus, grafana etc.) I discovered the subfolder "client". Installed all that and configured it to match my needs.
No I've got a question: do I need the prometheus-grafana installation procedure for the client or is the client independent from all that?
Sorry for this question: I searched the readme's but wasn't able to find this info
@CarstenStahlschmidt "prometheus-grafana " both are independent, i belive you refer to the HLExplorer as the client ? if yes , you do not need it in order to run prometheus-grafana

@nfrunza thanks for your reply. Indeed I meant HLExplorer with it's subfolder "client" where the dashboard is located. And if I understand correctly I can also use this client without having to install prometheus-grafana, right?

Hi! What is the best practice to run Explorer in production in multi-org setting? Is it possible to have one Explorer per network or it is required to run an Explorer per participant for segregation purposes?

@selvaraman as per security u cannot request from localhost ports. To do this u need to change few things in sawtooth explorer find server file where Express is initialized and add new package cors and use it ur problem will be solved

Hi I was successful in setting up hyperledger explorer. I wanted to make some changes in UI part. Is ther any documentation available on hyperledger explorere UI?
I think there is no documentation about UI part, unfortunately. But we always welcome your contribution. :slight_smile: @Sandraks94
You have another option that is issuing a JIRA of those changes, too.
The Linux Foundation’s CommunityBridge engineers are working on a tool to measure the health of critical open source projects and one of the key areas identified is QA Testing. They request that our communities provide honest and detailed information on testing tools and methodologies you use in your projects for us to come up with a detailed analysis, which they will share with all respondents and projects. https://www.surveymonkey.com/r/9H5G2GV. It’s only 5 questions long.

Hi! I am experiencing a strange behaviour. I have set the enableAuthentication to false in my connection-profile but the login page is still displayed. The weird thing is that no matter what credentials I enter I am successfully logged in as the server part knows to skip authentication but the client side is still displaying the login page... Does anyone know what might be the issue here?
I have looked at the code and to me it seems that enableAuthenitcation: false is not really doing what I would expect it to. I can see that all /api/* routes are protected with the auth-check middleware which requires that the request have a valid JWT token, which is generated at login. Also if there is no token in the localStorage, the client will automatically redirect itself to /login.
So am I missing something here or doesn't "enableAuthenitcation: false" work? If it works what is its functionality if not skipping the whole authenication process?
@SimonOberzan Thank you for raising an issue. I could reproduce the issue on my local, too. I create a new JIRA https://jira.hyperledger.org/browse/BE-729

Do you know if the explorer is compatible with Fabric 2.0? Here https://github.com/hyperledger/blockchain-explorer they say it is compatible up to 1.4.4. Has anyone tried? Do you know when will it be compatible? Thanks a lot.

Explorer does not support Fabric v2.0 yet.
I've not tried yet. Just created a new JIRA for that. https://jira.hyperledger.org/browse/BE-732
In our testing it has worked well so far. We can connect to the network, see peers of my org (if they have external endpoint), see channels, see some stats and transactions etc.
Great! Thank you for sharing
Thank you!
I will also make some tests. Today or tomorrow.
@jona-sc for confirmation: you did not make any change related to 2.0 and the current version of explorer worked out of the box on a fabric 2.0 network?
Yes that's right. On a fresh 2.0 network (i.e. I haven't tested a 1.4.x network that has had been upgraded to 2.0).

You don't need to do any steps for client separately. Just run `./start.sh`. If you still have same message (`No process name...`), that means you have some issue in bootup of explorer.

Hello. I am trying to install the explorer on a kubernetes cluster where I have a fabric v2 test networ running. For the connection config file of the explorer, here they say that the adminUser and adminPasswords are those of the Fabric CA: https://github.com/hyperledger/blockchain-explorer#70-configure-hyperledger-fabric . But I am using cryptogen and I don't think I have admin user and password for my network. Can you advise what to put in those adminUser and adminPasswords fields?
for info, my kubernetes pod fails with following logs:

Hi @woodyjon , as far as i know, blockchain explorer does not support latest version and yoiu migh get this errors due to incompatibility of their app. The latest release supports until 1.4.4 as stated in their release section: https://github.com/hyperledger/blockchain-explorer/releases
@vanitas92 on the Feb 18th, in this chat, someone said they installed it without any issue on a 2.0 network. That's why I thought it would be ok. But maybe I have another issue.
i wasn't aware of that, however, i would wait the developers to officially support it, as that user might have it working on a setting that you may not have and does not support.
I don't fully understand the "tlsEnable" and use of "grpcs" in the explorer config file. My network uses TLS as I use raft orderer, but my peers have tls enable (CORE_PEER_TLS_ENABLED=true) but client tls disabled (CORE_PEER_TLS_CLIENTAUTHREQUIRED=false). So do I need to put "tlsEnable" at true in the explorer config, and go I need to use grpcs instead of grpc?
yes you might be right about 2.0 support

Hi !
I am running sawtooth-explorer (https://github.com/hyperledger/sawtooth-explorer) with sawtooth-seth. The explorer shows some different character for payload. like the following,
Óäafdaaf79fca57d1685f3f31a0966807a90f400b2e23ea3c61ff06c3048a6ad1a6f408e5ce806006d0B03a2b36abfe6ca0751bbd3f3086a91b906e0641568b3069b3e3badc2ed33eab"6d50d258b0299eb4866e5676228d1c3dd42175fba0bbd94bb5c1b070c6b511e5408cd4e7109ee4b853fa32e2d599d885f5296136f619ea(Ùò
Can you please help me to remove those characters ?
Yes, in that case, you need to set `true` to `tlsEnable` in your explorer configuration. But you don't need to take care about grpc prefix at peer URL. That should be adjusted automatically. @woodyjon
In [hyperledger explorer](https://github.com/hyperledger/blockchain-explorer), fabric is supported (now we're working to support of iroha). I think you might be able to get some information at #sawtooth channel. @selvaraman
Could someone please help me solve the problem of not been able to connect hyperledger explorer to hyperledger fabric via http:/localhost:8080 and i have attached the screenshots of my log files, thanks in advance

thanks @nekia . I'm still not able to connect the explorer to the peer, I'm not sure what is my issue, but I put this aside for now, waiting that you confirm the support for 2.0
Can you share the following information?
* Fabric version
* Explore version
* Using docker or launch from your local source tree
* About your fabric network (first-network, test-network)
* Your config,Jason & connection profile
@samurai
I am using all the tools, software and configuration files, that were used in the example demonstrated on the website below:- https://medium.com/coinmonks/hyperledger-explorer-quick-start-50a49c6d7957
hello @nekia for running the explorer in production what are the necessary changes in terms of config and security perspective that one should make to the explorer?
OK, these steps are partially out of date.
In `App Config`, you need to follow the current syntax that you can see in the original [config.json](https://github.com/hyperledger/blockchain-explorer/blob/v1.0.0-rc2/app/platform/fabric/config.json) and [connection profile](https://github.com/hyperledger/blockchain-explorer/blob/v1.0.0-rc2/app/platform/fabric/connection-profile/first-network.json).
And you don't need the step `serve -s build`.
ok and thanks a lot

It looks like to me that you are running Explorer in docker container. But the crypto files are still placed on your local file system. I think you need to mount these files on docker volume. @metadata
I think it depends on your requirement in your service.
@nekia I'm mounting the `crypto` dir.
```
volumes:
- /home/delta/GoWorkspace/src/github.com/hyperledger/blockchain-explorer/app/platform/fabric/config.json:/opt/explorer/app/platform/fabric/config.json:ro

- /home/delta/GoWorkspace/src/github.com/testchain/networks/crypto-config:/tmp/crypto:ro
- walletstore:/opt/wallet
```
In `app/platform/fabric/connection-profile/mynetwork.json` file I've mentioned the local file system path. Is it correct?
got it.
Now, I'm getiing different error:

I guess it might be because of OOM https://docs.docker.com/compose/compose-file/#out-of-memory-exceptions-oome Your resource constraint is too strict, I think. @metadata
Not working even after removing the resource limit. throwing same error
How to enable debug mode in compose file?
How to enable debug mode(explorer logs to debug mode) in compose file?
Has left the channel.
@nekia fixed it. Yes it was a resource management issue. Actually after your suggestion I removed the restriction from `explorerdb` but forgot to remove it from `explorer`.

:thumbsup:
Which explorer images are you using? 1.0.0-rc2 on docker hub or your own image built from the latest master? The previous one doesn't have function to control logging via env variable yet.
I'm using `1.0.0-rc2`.
Any previous version that supports log level control?
No, unfortunately. Wait for the next release, or you can use `build_docker_image.sh` to build your own container image. If you push it to your docker hub repo, you'll be able to refer it from your swarm environment on gcp.
ok. Thanks @nekia

Is there any timeline for 2.0 support or an issue tracking this?
On the Github Network tab I saw a
related commit from someone at Fujitsu two days ago: https://github.com/nekia/blockchain-explorer/commit/3ee056a0f34bd85612883d5f219464e559e2716e
The JIRA issue seems to be here: https://jira.hyperledger.org/browse/BE-732
I prepared that change. Unfortunately, this project currently has less resource and approval process of PR is pending.
Thanks for the reply. Is the linked commit working for you with Fabric 2.0?
Yes, as far as running our test scenarios, it seems to be fine.
If some contributor get joined this project, we could have a progress.
Thanks a lot :)

But after I restart explorer docker using 'docker restart explorer.example.com' it works. What could be the reason and what could be the solution. I guess the reason might be that when explorer try to connect to db, the db was not ready.
Please help me to find the solution.
Please help me to find the solution so that I don not have to restart the explorer everytime. It starts working the first time.
Has joined the channel.
The current workaround is putting some delay before launching explorer in command of docker-compose.yaml https://github.com/hyperledger/blockchain-explorer/blob/master/docker-compose.yaml#L50 @ZainabM
@nekia If the changes requested in https://github.com/hyperledger/blockchain-explorer/pull/84 is accepted, then the sleep won't be required.

You need to change the path to secret key to your own one in the connection profile.

Hello, I am trying to setup explorer for a network running with Fabric. The configuration of the network is quite simple as it only has an org and a peer. The network is running normally, and the explorer starts but it gives me the following error on the command line:

8080 port seems to be in use. I think you need to make sure that any explorers have not been executed by ruuning `./stop.sh` or `lsof -i :8080` @Suarez 3

I am facing the above
error
any one can help me on this
You seems not to be in appropriate channel for your issue. @PraveenKumar1984 Are you talking about composer?
I am running explorer via docker-compose and works like a charm. But it doesn't list the installed chaincodes. I am running the latest HL image and underlaying 2.0 network
I think `2.0` is still not supported by `explorer`. As per the docs, till `1.4.4` is supported. Also, the `digest(sha256 hash)` of `explorer:1.0.0-rc2` and `explorer:latest` images is same. hence both the images are same.
Oh. The beauty is it supports rest of the page/features. Just that unable to display the installed chaincode.
Does this uses the node SDK to fetch the information ?
1. I guess it is because the major change between `1.4.4` and `2.0` is in the chaincode part only.
2. I don't think explorer depends on any sdk because I'm using `sdk-go` and `sdk-node` is not even installed on my machine.
Thanks, Any idea on how to debug this scenario then ?
Thanks, Any idea on how to debug this scenario?
I think the only solution u have is to downgrade the fabric to 1.4.4 OR wait for new release.
u can share the explorer logs here, I hope someone would help.
Yes, everything of the explorer will work with a `2.0` network except listing available chaincode.
I'm also interested to know when there will be an update to work with the new chaincode lifecycle. Should require a small change.

Explorer seems to receive a signal (SIGTERM or SIGINT) from outside of app. Do you have more detail (console log of explorer or event info/log of the instance on your cloud)? @metadata
Let me check it again. Actually I have restarted the explorer again. Since this is re-occurring issue so I hope I can provide the logs again.
Hello @nekia Only app logs are available.I'm using docker-compose hence i checked inside container and only found app logs . no console logs are available.

Explorer uses `sdk-node` to access fabric network. Currently we are waiting for the official release of `sdk-node` for HLF 2.0.
@nekia I got it why explorer is closing.

@nekia I got it why explorer is closing. CPU usage is very high
```
CONTAINER ID NAME CPU % MEM USAGE / LIMIT MEM % NET I/O BLOCK I/O PIDS

```
@nekia Please suggest any solution?
During the intense CPU usage, can you get log from explorer containers? `docker cp explorer_explorer.1.smsifbhr0q0mg4zs30eaw29hm:/opt/logs .`
hello @nekia I used the same command but still `console` dir is not present in `logs` dir.
That's fine. Console log is redirected to stdout. So console dir is not generated in docker environment.
What I observed is once the explorer got SIGNTERM or SIGINT then from at this point, the CPU utilization start increasing.

@jona-sc @Diegoescalonaro @easeev In v1.0.0-rc3, the multi-org feature got supported. If you still have any interests with the feature in your use cases, it might be useful for you. And we would be happy if you give us any feedbacks.
@nekia That's great to hear. Do you have a short summary of how the feature works?
Thanks for your response. We don't have any document yet, but it's straightforward. Please prepare config.json as below and connection profile for each org.
```json
{
"network-configs": {
"org1-network": {
"name": "org1-network",
"profile": "./connection-profile/org1-network.json"
},
"org2-network": {
"name": "org2-network",
"profile": "./connection-profile/org2-network.json"
}
},
"license": "Apache-2.0"
}
```
We'll add a short steps how to use the multi-org feature in Explorer document.

Hi,
The affiliation details is defined in your Fabric-Ca configuration
I am looking into integrating Explorer into my application backend. My application uses Iroha, I'm curious how relevant/important it is to explorer developers for Iroha integration?

Hi everyone! I have 4 different servers running some instances of Fabric and I have the 5th one where I'm trying to install the Hyperledger Explorer. Does anyone already did the installation on a different server? I tried many times but maybe I'm missing something

The above information might be useful to start learning how to use fabric-ca environment. @ravinayag
Explorer should work in the environment you have. What kind of errors do you have? You can find logs under logs directory. @jaraujo
Iroha integration just started in the last couple of months and we're really excited about the expansion of support for platform in Explorer. But that's also true that we haven't have enough resources for moving further the implementation at this moment. So we are always welcoming a new contribution.
Ugh, I'd love to work on this myself if I didn't have my hands full already :(
the official docs has many information, but not friendly.. anyway, i do my exploration. Thanks @nekia for sharing..

does hyperledger explorer work with fabric 2.0
which version of explorer will work with fabric 2.0
We've not supported fabric 2.x yet. The work item is currently pending until official releas of fabric-sdk-node which explorer is depending on. But even after the release we may not be able to provide support of fabric 2.x quickly because most of administrative API (such as querying of channel, chaincode, etc.) in fabric-sdk-node have been obsoleted in the latest version. @uallknowmatt
Has joined the channel.
You can run it and connect it with Fabric 2.0 just fine, just the chaincode view won't show any chaincodes

Hello,
I am trying to setup hyperledger explorer for fabric 1.4 version
I have 6 orgs and 1 peer per orgs network
but after setting the explorer I am getting only one node and 1 peer. I should get all the nodes and peers in the dashboard.
But I am not getting that. Can anyone tell me how to fix this?
Explorer is using service discovery to detect peers. Each peer you want to see on the dashboard need to be configured with EXTERNAL_ENDPOINT setting
https://hyperledger-fabric.readthedocs.io/en/release-2.0/discovery-overview.html#how-service-discovery-works-in-fabric
Do you have this kind of setting on each peer? @DimpleKanwar

Hi! I'm trying to install Explorer to monitor my Fabric Network. I'm at section 8 in the README https://github.com/hyperledger/blockchain-explorer. It tells me to install HP Composer. But on the Composer Site it says Composer is deprecated https://hyperledger.github.io/composer/latest/installing/development-tools
Is the Composer an optional part for explorer, or must I install it?
@DarkTron if you are using fabric network . please follow the https://github.com/hyperledger/blockchain-explorer#Fabric-Network-Setup.
It's not need for fabric network
ok thank you
@SharedMocha No it's not possible and we don't have any plan to support this kind of feature so far.

Hi, I run a docker network with many services under a single domain (example.net). each of the service is exposed through a proxy pass by an nginx server (example.net/service1 -> upsteam service1:port). I am trying to expose the hyperledger explorer to a subdomain (example.net/fabric-explorer) but the resources (styles, js, etc...) are loading from. basepath (exampl.net/static/css...). I am tried to find a way to specify in a config but couldn't find a way, did I miss it or the explorer simply doesn't support subpaths ?
Thank @nekia for your reply
HI- Can anyone point me to the process or code that fetches apps/db/console logs in the GitHub repo? I tried looking into below settings but wasn't sure how explorer is fetching logs from peers/nodes

- LOG_LEVEL_CONSOLE=debug

Hi @BancuStefan I could recreate your issue on my local, too. The following info might be useful for the issue. In my local, although still I see an error message regarding websocket in console on browser, explorer dashboard has been shown with using a subdomain.
https://stackoverflow.com/questions/47017142/reverse-proxy-nginx-no-such-file-or-directory
Explorer isn't fetch any log from fabric peers. It's just collecting logs of the node.js middleware itself.

@nekia : I didn't see the subdomain example other than subdomain.domain.com. I need a domain.com/subdomain. I was just wondering if there is a config option where you could specify a folder under which your project is deployed so it makes the front-end retrieve files from that path (domain.com/subdomain/static/javascriptfile.js) and also the rest API from domain.com/subdomain/login ...)
Explorer doesn't have that kind of config option. nginx will be able to handle the use case without any changes to Explorer, I think.

@nekia thankyou , that solved my segmentation issues.
Im facing new problem- ca admin issue when starting my explorer docker image,
Note : my firstnetwork-connection.json file is same where i use for manual start.sh and Docker image.

I guess you are running both fabric network and explorer on same machine. You need to make explorer container join to same network with fabric network. You can specify the network in your docker-compose.yaml.
https://github.com/hyperledger/blockchain-explorer/blob/master/docker-compose.yaml#L14
And also you need to rephrase all URLs in your connection profile from localhost:* to actual hostname which valid within the docker network. @ravinayag
What kind of dump i.....:( .
Didnt realize this name conversion mistake, thats the good catch.
After changing hostname (fqdn) docker image was able run with no errors. @nekia Thank you for your help. ( Happy to share Thank you points)

Sorry, this information is out of date. Explorer is not using these format anymore, using a wallet instead.

hi, i am using fabric release v2.1, and explorer is ok except chaincode, i.e. displays 0 chaincodes.
I think they are working on v2.1 support right now -> https://jira.hyperledger.org/projects/BE/issues/BE-732
that's three month ago. good news!
that's three months ago. good news!
Currently you can't specify flexibly any locations where your credentials are stored. Explorer is referring hard coded location ( `./wallet` ) when loading admin identity in bootup of middle layer. And the function for multiple users to login to dashboard has been incomplete yet.

Hi all, can anyone help me with a new setup of the explorer? I need to create a new tab called "Security" in the explorer and add some new charts e.g. a map with blinking points at MSP addresses or else. I've already tried to read the code for the Header 'HeaderView.js' and included a new link {to: '/security', label: SECURITY} but it didn´t work. Do I miss something in another file? Would be so great if someone could help. Need this for my college seminar. Thanks in advance

Any suggestions on how to set up a dev environment? What is your setup?

Hi everyone, can someone explain me how to link hyperledger explorer with mutual TLS in fabric please?
I managed to use it without mutual TLS but then i can't manage to do it (i have an error "failed to verify client's certificate: unknown authority server but i don't know how to specify it in the JSON)
@sam94 Which version of explorer are you using? We tested connectivity of Explorer with mutual TLS before and it worked at that time.
Log of the test is below
https://jira.hyperledger.org/browse/BE-568
> The important configuration is adding not only msp/tlscacerts but also ca cert which is referred by fabric-ca (org*.example.com/ca/ca.org*.example.com-cert.pem) to TLS_CLIENTROOTCAS_FILES.
We didn't need any changes to Explorer, you only need to setup your fabric network appropriately for mutual TLS
I am using the branch master, since I updated with your commit from 12th june, it works but the block event has an issue, it is trying to contact the peer without providing a certificate (error from peer logs : TLS handshake failed with error tls: client didn't provide a certificate server=PeerServer)
Also, to make it works I used this post: https://stackoverflow.com/questions/56774550/how-to-configure-mutual-tls-in-hyperledger-fabric (added the call of setTlsClientCertAndKey in FabricGateway/getDiscoveryResult)
UPDATE: it works correctly using your last commit and adding the certs in the FabricGateway/getDiscoveryResult setTlsClientCertAndKey call
peer1.org1.example.com
peer1.org2.example.com
peer0.org1.example.com
peer0.org2.example.com
ca_peerOrg2
ca_peerOrg1
orderer.example.com
This is what my network setup.
After instantiation of my chaincode, I am getting transaction count as 0 in chaincode's tab. But It is 4 in dashboard and channel's tab. What is the reason? Can someone please explain?
Thank you for sharing your work. We'll fix this issue based on the information you shared. Of course, always welcome your contribution as well :slight_smile:
@sam94
Probably gateway class of fabric-sdk-node is in charge of calling setTlsClientCertAndKey(). So user of SDK might only need to set clientTlsIdentity to option when connecting gateway.
https://github.com/hyperledger/fabric-sdk-node/blob/b8cc3a8f6ccca55589c60efd98b011a71eab0ea0/fabric-network/src/gateway.ts#L309
In chaincode tab, the transaction count submitted to each chaincode are displayed. In dashboard and channel tab, not only these count, but also count of other transaction such as configuration change are displayed with added. @selvaraman

do you know how I can add username/password for accessing its web UI?
I created a new tab called security and now I want to implement some charts, a map and a blockchain visualization with links to the last blocks in the chain.
1. I dont know how to implement the metric 'inter-block time (min)', so the time passing by between to blocks created. I already created a sql data operation in the MetricService.js file but there are a few other files I have to update, I know. I'm not sure if my way to do it, is right. You have any ideas concerning this problem?
2. I want to display some blocks as my blockchain and like to implement a link on each of them which links to details of the last, the penultimate, the last but two and so on... block of the blockchain in the database/fabric. There is a details view already in the hyperledger explorer and a link on it in the timestream component, but i just want to have the blocks with the links and no further information in this view. Can I implement it somehow like this: link = BlockDetails(max(blocknum)?
3. Can I add a 24h-average-line in the charts? If so, how?
4. I cant find the file .env.local. When I want to create one, it says there is already a file with this name but searching for it does not show any file. Just one hidden file, but I cant find it/open it/localise it. In the .gitignore file the .env.local file is linked.
We've not supported multiple accounts yet.
ok, thanks.
I think you can calculate 'inter-block time (min)' from timestamp that block was created as you mentioned.
2nd question is difficult to answer because it's completely nothing to do with Explorer. I think you can do as you want.
We are using recharts so you'll be able to use the following to draw constant line in the chart.
http://recharts.org/en-US/api/ReferenceLine
The last one seems to be your local specific issue, so I have no idea. Thanks

This error message comes from fabric-sdk-node. Can you check log of each peer to see if there is any errors?
I noticed that you make TLS disabled in your fabric network according to the connection profile you shared. Could you try to change peer URL from `grpcs://` to `grpc://`?
@pleyades We just started working on adding multiple user management as next work item. https://jira.hyperledger.org/browse/BE-767

Got it, thank you for clarification! We will wait)
in this case we have to disable the TLS ?
@nekia
It depends on your fabric network. If you disable TLS on your network, you have to set `false` to `enableTLS` and use `grpc://` in peer url instead, in the connection profile. @ashoksiri

Hi again, I have another question/issue with the latest version of the explorer. Seems that the login page does not work as expected because I'm able to login with fake users when enableAuthentication is set to true
I have:
```
{
"network-configs": {
"first-network": {
"name": "firstnetwork",
"profile": "./connection-profile/first-network.json",
"enableAuthentication": true
}
},
"license": "Apache-2.0"
}
```
and inside first-network.json I set the user and password
https://github.com/hyperledger/blockchain-explorer/pull/
We're updating README now for adding more detail of each configuration. You can see its preview in the above PR. You need to configure `enableAuthentication` in your connection profile (`first-network.json`). @javiJavi

ok thanks @nekia then if I undestood correctly I need to change my configuration from this:
```
"client": {
"adminUser": "admin",
"adminPassword": "adminpw",
"enableAuthentication": true,
"tlsEnable": true,
"organization": "Org1"
},
```
to the format specified in the new configuration
Correct.
seems that with the new info is not working. I updated my config to:
```
client:
{ caCredential: { id: 'admin', password: 'adminpw' },
enableAuthentication: true,
tlsEnable: true,
organization: 'Org3' },
channels: { mychannel: { orderers: [Array], peers: [Object] } },
organizations:
{ Org3:
{ mspid: 'Org3MSP',
fullpath: true,
adminPrivateKey: [Object],
signedCert: [Object],
peers: [Array] } },
```
But I got an error in the logs:

We added the support of PEM string format in the recent commit. We've not released new container image including this change yet (we'll do within this week unless we have a big issue with the current codebase), but you can evaluate it if need.
@Javi sorry, I misread. You're using v1.1.0 Docker image, right? In this case, you need to use old format of connection profile.
```
"client": {
"adminUser": "admin",
"adminPassword": "adminpw",
"enableAuthentication": true,
"tlsEnable": true,
"organization": "Org1"
},
```
yes @nekia I'm trying to use 1.1.0 but is not working, I'm able to login with any user using the snippet code you sent
Thanks, we could reproduce the issue you shared. It's fixed on my local and we're now working on testing it. We'll update you shortly.
Thank you for the great release 1.1, working perfectly for me! The README-CONFIG was quite helpful in figuring out the needed changes to the config file
FYI. As you might already know.

Hi, I have some trouble reading/interpreting information on explorer, might be something wrong with my fabric network but thought i'd ask here. (using fabric 2.1, explorer 1.1, couchdb as statedb, pdc's)
1) What could be the cause of that previous hash does not correspond to the block hash of previous block? (in "BLOCKS" view)
3) What does "Validation Code: ENDORSEMENT_POLICY_FAILURE" in transaction details imply? (I can query the ledger and get the transaction data by GetState() so I thought everything was fine until i checked explorer, I see no errors in docker or elsewhere)
perfect @nekia thanks for the info
Hi, was just wondering if explorer supports pdc? Or might usage of pdc be the cause of differences in previous hash and block hash's?
pdc means `private data collection`?
explorer doesn't support pdc.
That's because of bug that was fixed today's release.
https://github.com/hyperledger/blockchain-explorer/pull/141

},
"adminCredential": {

Both CaCredential and adminCredential has "id" field
alright..i will try this..thanx for the reply.
take reference from https://github.com/hyperledger/blockchain-explorer/blob/master/app/platform/fabric/connection-profile/first-network.json
Alright thanks! Working :)
👍
so i am using master branch of explorer and fabric 1.4.7 and trying to connect balance transfer network..should work right?
yes, it should work
Hyperledger Explorer Version v1.1.1 should support Fabric Version v1.4.0 to v2.1.1
Screenshot from 2020-07-20 20-20-24.png
have a look at above error and plz let me know what u think about it
Peer url is mapped to `localhost`. I guess you're getting Explorer started as container service. The mapping shouldn't be happened in that case.
Please make sure `DISCOVERY_AS_LOCALHOST` is defined on Explorer container service. The detail is as follow.
https://github.com/hyperledger/blockchain-explorer/blob/master/README-CONFIG.md#run-hyperledger-explorer-using-docker-compose
Please make sure `DISCOVERY_AS_LOCALHOST` is set to `false` on Explorer container service. The detail is as follow.

Hyperledger Explorer sync -- I am able to bring-up Hyperledger explorer using docker-compose.yaml but sync is not happening. we have syncstart.sh in case if I use full source code of explorer. But in case of docker-compose.yaml, how to sync ledger data with explorer ?
@nekia could you please help ?
this DISCOVERY_AS_LOCALHOST is set to false is being used..getting the same error
In url, use "grpc://peer0.org1.example.com:7051"
Screenshot from 2020-07-21 11-41-50.png
m thinking its a database issue..
Are you using container service or you download full explorer source code and trying it?
trying to run in container
ok then bring down your containers and bring it up again
docker-compose down -v
docker-compose up -d
in ca-org1, also change localhost
change this : https://localhost:7054 --> as you did for peers
alright
same error..
let me try the non docker setup
Screenshot from 2020-07-21 12-15-59.png
looks like node package error..is it something to do with node version?
please check https://github.com/hyperledger/blockchain-explorer; release notes
check node version for your fabric version
I've not tried that using docker-compose yet. I think we probably need to override `explorerconfig.json` and compose command-line.
Thanks for your response, let me try with explorerconfig.json and bring-up docker-compose.yaml
Thanks
Screenshot from 2020-07-24 18-01-51.png
path is correct...what could be the issue??
You seem to specify the location of credential with host path. You need the absolute path on container like `/tmp/crypto/peerOrganizations/...`. You should specify the volume to mount the credential artifacts in your docker compose like [this entry](https://github.com/hyperledger/blockchain-explorer/blob/master/docker-compose.yaml#L51).
Please refer the following in detail
https://github.com/hyperledger/blockchain-explorer/blob/master/README-CONFIG.md#run-hyperledger-explorer-using-docker-compose
Does the 5th feature provide access to Fabric CA users(non admin users) ?

Hello. I'm using the latest version of explorer with fabric and I'm seeing the transaction _values_ of the read/write sets as a buffer. Is this expected, or am I doing something wrong? With the node-sdk, using `channel.queryTransaction(txId)` from `fabric-client 1.4.8` I see the read/write set showing up as a string, as I would expect. I'm not sure why I am seeing a different result with explorer.
Clipboard - July 28, 2020 4:45 PM
No, fabric CA user which you need to set in connection profile for Explorer must have `admin` attribute in `hf.Registrar.Roles`.
Because Explorer need `admin` when accessing chaincode information on Fabric network (although it basically depends on the configuration of Fabric network).
Could you provide more detail of your issue? The version of Explorer/Fabric you're using, the steps to reproduce the issue, etc.
Thank you for sharing the issue. We'll see if the issue is recreated our side.
In the latest fabric Node.js sdk, work of data unmarshalling of the result returned from API are left to user, not SDK. It might be causing the issue.

I am using blockchain explorer with version 0.3.5.1, I try to call the api such as "/api/channels/info", but it offen shows "waiting for available sockets" in the web explorer(at this time, using curl to call the api at the server running the blockchain explorer backend, also blocked) , when the blockchain explorer web console explored in the web explorer.
When the blockchain explorer web console closed ,the called api returns normally. It seems the the blockchain explorer web console occupy too many sockets.
So is there any config to make more sockets useful in blockchain explorer?Or any other workable suggestion?
I strongly recommend to use the latest Explorer `v1.1.1`. `v0.3.5.1` has been out of date.
Yes, I know 0.3.5.1 is out of date, but it is the highest version supporting fabric 1.1( for some reason ,this fabric version can't be upgraded)@nekia

Ok I see.
There is not any good suggestion for that. sorry
Can we leverage explorer REST APIs and pull the network information to show in a custom UI? If yes, what would be the approach to do the same ?
Thank you all the same.
Yes, I think, you can. You can try it out on `http://localhost:8080/api-docs`.
https://chat.hyperledger.org/channel/fabric-sdk-node?msg=acq5JimKYGYmSPWGd
It's based on the specification of fabric-sdk-node. Please refer the above link for detail. We're considering if we should add a new option to leave choices to Explorer users for switching the represent format of read/write set value among 'Buffer array(default)', 'String value.toString('utf-8')' or 'Hex value.toString('hex')'.
Thanks for following up. That makes sense. I'd guess a lot of people store text (even json) and would benefit from it being shown as a string in explorer, but that's just my opinion.

Hi @nekia ! I have successfully deployed a Hyperledger Explorer in a Kubernetes cluster with the latest version and a Hyperledger Fabric 2.2 network. But I found a problem with the code of the Explorer when getting the admin ID and password. The config is looking for a field y the connection-profile which doesn't exist unless you add it. So or the connection-profile example is not updated or the code has a bug I think
And I have another question, Is there any way to set a base path for the front-end ?? When I expose the explorer in a path like /explorer I can't see the app
Thanks @AlbertoCarmona Do you mean the following field?

Which version of Explorer are you using? This error should be fixed in v1.1.1 release with the following change
https://github.com/hyperledger/blockchain-explorer/commit/d635e39758fbde01b537d5042052cb1d8552d612
I referred latest documentation at git-hub . Version mentioned in docker-compose file is 2.1 and it refers to hyperledger/explorer:latest image
Please ensure `latest` tag is pointing `1.1.1` by running `docker pull hyperleger/explorer:1.1.1` once.
I changed version in docker-compose to 1.1.1 but still same error
Sorry I misread error message. Can you see peers and explorer containers within same network? `docker network inspect [your network name]` as mentioned in [README-CONFIG](https://github.com/hyperledger/blockchain-explorer/blob/master/README-CONFIG.md#run-hyperledger-explorer-using-docker-compose)
But my peers are running on Azure AKS . Where as docker is running locally. So I dont think both will be on same network.
I see. Each peer is required to be reachable from Explorer by using the above hostname.
Peers are reachable. Exposed through ingress. I am able to invoke a chaincode using sdk . Exploerer is also discovering but after that not able to connect

Yes, I mean that field. In the example does't appear
Thanks! This could be useful but sadly I'm not using Nginx. I'm using Red Hat's API Gateway
By the way, is the register functionality currently working ?
Ok, thanks. We'll update the example
In case starting Explorer using the latest codebase, it should work. We are about to complete adding user management support soon. The next release v1.1.2 including this feature will coming soon (around early next week, I think).

and network link does not work
Great! What was the cause of your previous issue?
Please try it again after delete all volumes mounted to Explorer container. Explorer stores credentials you configured in connection profile into a wallet on its local file system. If Explorer is still referring old stored credential even after Fabric network restarted, this `access denied` error can be happened.
What does `network link does not work` mean?
Thank you for update. We'll consider adding a new configuration to customize base route path to Explorer.

@carlosalca i have verified with CA in that new release . It's working . can you refer this CA configuration also please check your configuration and verify your file path in that location is there or not
first-network copy.json.txt
Thanks! I just realized that I was writting the CA config inside the peer config, my mistake :sweat_smile: Sorry!

@nekia : https://github.com/saanvijay/hyperledger-explorer-made-easy I have automated all the configuration files (config.json, docker-composer.yaml, connection-profile/network-name.json), user just has to pass json args. It may be helpful for someone who is looking for quick setup in explorer.
Great contribution :thumbsup: Thanks @saanvijay I'll try using it.
i too face same problem, but didnt configure the CA, does it mandatory ?

You need to specify at least 1 peer in the organizations.
Explorer v1.1.2 has been released!
great, it solved my error, i dont how it missed. anyway thanks nekia..
I'll start exploring the new feature of user managment
:thumbsup:
Explorer v1.1.2 has been released . It supports v1.4.0 to v2.2.0 fabric version
How to confirm my docker image is latest v1.1.2 ?
you can run `docker image ls` to see all your image tags
you can run `docker image ls` to see all your images and tags.
i get only the 'latest' name tag, it doesnt say Version number
explorer$ docker image ls | grep expl
hyperledger/explorer-db latest 5217ac66f395 3 days ago 97.7MB
hyperledger/explorer latest 3f61c0231202 3 days ago 174MB
because you are grepping for the latest tag. just run `docker image ls` and check the tags
no, you can check command, i grepping with 'expl'

Hi @nekia I has been playing with the new users feature. I wondered about the persistance if theese new user and looked into the code. I don't know exactly if I'm righ but the new users are intended to be stored in the PostgreSQL database. I found a JS file (app/sequelize/sequelize.js) were the connection to the DB is defined but the address might be hardcoded:
```
/**
* SPDX-License-Identifier: Apache-2.0
*/
const Sequelize = require('sequelize');
const sequelize = new Sequelize(
'postgres://postgres:postgres@localhost:5432/fabricexplorer',
{ logging: false }
);
module.exports = sequelize;
```
If this is true, users are not being stored correctly, could you confirm, please, if I'm right ?
Thanks a lot!

i have other option to check the package.json file version after login to docker image.
just try pulling again, if the status was: `Status: Image is up to date for hyperledger/explorer:latest` it means your image is V.1.1.2. if not, let it download the latest!

My image is latest and I pulled last night.
So my Q, how do i confirm image version..
Anyway i confirmed with package.json file. that gives version details..
I added this two lines in main.js file
var expbuildver = require('./package.json');
console.log("Explorer Build version : ", expbuildver.version);

I don't know. I guess it is a problem with Docker and they should think about it.
Sorry for making you confused. That file (I guess, `sequelize/sequelize.js`) is not used any more.
Sorry for making you confused. That file is not used any more.
You can see the logic to persist user info to db in [app/persistence/postgreSQL/PgService.js](https://github.com/hyperledger/blockchain-explorer/blob/v1.1.2/app/persistence/postgreSQL/PgService.js)
https://docs.docker.com/engine/reference/commandline/images/#list-image-digests
Another option is comparing digest between the image on your local and the one on [docker hub](https://hub.docker.com/layers/hyperledger/explorer/1.1.2/images/sha256-051fd64c09f72bd9f8bb8e8d4375243f09b31d235639d6aab9e64b44d8aaef31?context=explore)
yeah, thats another option but its hard to chase version locally if its not matched.
Thanks! I'll have a look

which file should this be getting from `this.config.client.caCredential.id`?
which version of explorer you are using? Does your config file contains the following "caCredential": {

},
"adminCredential": {

you can use opensource explorer automation tool to generate all your config files and it will bring up explorer https://github.com/saanvijay/hyperledger-explorer-made-easy

yes, I added that to the profile.
@saanvijay I really want to be able to get the explorer working with minifabric, but even following your example, things just simply not working. keep getting all sort of error.

You probably need to add `adminCredential` to your connection profile.
guys, I've added Explorer to minifabric, now if you are using minifabric stand up your fabric network, boot up Explorer against that network will be simply a command like this `minifab explorerup`
the result of that command will show you a url which you can use to access explorer user interface.
quick and easy.
try minifabric and find it here https://github.com/litong01/minifabric
got it all working. and added explorer to minifabric.
@nekia thanks. client.adminCredential is fixed. but wallet creation failure remains.

Hi everyone. Is there a way to run hyperledger-explorer without the private key of org admin? Hyperledger-explorer provides the feature of `Monitoring multiple organizations`(https://github.com/hyperledger/blockchain-explorer/blob/master/README-CONFIG.md#monitoring-multiple-organizations). If the connection profiles of every org require the adminPrivateKeys all admin credential would be stored at a single place which I want to avoid.
How do you asses the security risk of the overall hyperledger fabric network when running hyperledger-explorer with multiple organizations?
Hi everyone. Is there a way to run hyperledger-explorer without private key of org admin?
@RobinKlemens take a look at minifabric which sets up everything easily including using explorer.
The idea is that each org manages their own nodes. In a real production env, I do not think two orgs will share one machine for things and will share their admin/private keys. Each org will hold their own keys. Explorer user from one org should only be able to use their own admin key to see what is on the network.
You see the cases that multiple orgs have keys on the single machine due to these setups are all test env or dev env. Real production env would not have multiple org peers or orderers running on one machine, these keys will not be altogether neither.
Thanks for your response @tongli . Alright, I agree to the point that in production env every org would host there own infrastructure. For sure the peers and orderer and hyperledger-explorer instances as well.
Still, the private key of an admin is required. As far as I understand hyperledger-explorer it uses service discovery to retrieve information of the network. But wouldn't a private key of a client be enough (e.g. explorer client with affiliations such as org1.explorer)? I don't want to store the private key of the admin in the explorer container.
@RobinKlemens I am not an explorer expert, but when I added explorer to minifabric, I remember you just need to configure the container to use the private key. Do not think explorer expose the private key any where, but in any case, since explorer use the key in theory, you will have to secure the explorer itself.
@tongli I don't think explorer exposes the private key. And yes, the explorer container needs extra security as long as the private key of the admin is required.
I'd love to get some additional information about this from the maintainers.
Best Robin
We're using a wallet to store an identity (certificate and private key) on a machine where Explorer is running.
If using HSM wallet and providing a pin to access the HSM from a secret artifactory, it might be more secure.
In this case we also need using Fabric-CA to retrieve an admin identity for avoiding to pass a plain private key to Explorer.
i still get troubles in building explorer with identity error:

i noticed that explorer using discovery enabled = true, so how to fix these errors.
Which version of Explorer are you using ?
The url of each peer seems to be mapped to localhost. Please have a look at the following configuration (`- DISCOVERY_AS_LOCALHOST=false`)in your `docker-compose.yml`
https://github.com/hyperledger/blockchain-explorer/blob/master/README-CONFIG.md#run-hyperledger-explorer-using-docker-compose
@bh4rtp
@nekia i am using 1.1.2 release. and my network is built locally by docker containers.
should i set DISCOVERY_AS_LOCALHOST=true?
and i suggest that the discovery service should be disabled or can be configured, i.e. discovery: { enabled: false}, in the explorer.
You should set `DISCOVERY_AS_LOCALHOST=false`. And please make sure peer url in your connection profile is configured correctly, that means the url should be kinda hostname valid within your docker network instead of localhost.
@nekia solved. i configured the error network for `explorer` and `explorer-db`, mistook '-' as '.'.:grinning:
@nekia discovery problems solved.
in the docker-compose.yaml, i comment the command line for `explorer`, why does the explorer still start to run when docker-compose up?
@nekia discovery problems are solved. but there comes a new problem:
```explorer.example.com | [2020-09-02T04:33:30.891] [ERROR] FabricGateway - Error: Committer must be connected
```
what does this mean? previous `Error: Endorser must be connected` does not occur.
finally get the explorer running. but login failed. which user and password should i use to login the explorer?
my client configurations:
```"client": {
"tlsEnable": true,
"caCredential": {
"id": "admin",
"password": "adminpw"
},
"adminCredential": {
"id": "exploreradmin",
"password": "exploreradminpw"
},
"enableAuthentication": true,
"organization": "Org1MSP",
"connection": {
"timeout": {
"peer": {
"endorser": "6000",
"eventHub": "6000",
"eventReg": "6000"
},
"orderer": "6000"
}
}
}```
exploreradmin/exploreradminpw can not login the explorer.
there still has an error:
```Error: Failed to authorize invocation due to failed ACL check: Failed verifying that proposal's creator satisfies local MSP principal during channelless check policy with policy [Admins]: [This identity is not an admin]```
the explorer only displays the nodes of the network, all other things, i.e. blocks, transactions and chaincodes, are zeros.
@bh4rtp As described in [README-CONFIG | Uing Fabric CA](https://github.com/hyperledger/blockchain-explorer/blob/master/README-CONFIG.md#using-fabric-ca), you need to specify affiliation to be used for Admin credential, too
@nekia yes. i specified an affiliation, i.e. org1.department1. but i don't know where org1.department1 is set to be an admin in the ca-server configuration yaml.
@nekia my network is created by `cryptogen` tool. should i use certificates and not ca authorities for configuration of connection profile?
Yes, you should because it's easier for configuration to use generated credentials. Once you can see Explorer is working fine, then you can try using fabric CA again.
Caveat: if you make any mistake on fabric CA once, you need to delete your wallet and restart your fabric CA server because incorrect identity has already been registered to the server and stored in your wallet. @bh4rtp
@nekia successfully got the explorer running now. thanks.
if i set `"enableAuthentication": true`, should i login in the explorer using exploreradmin/exploreradminpwd？
Yes, you can use id/password you specify in the connection profile. You can also register a new user which is used for login, via GUI/API.
i cannot login. it tells invalid user or password. so i set enableAuthentication = false.
In example of README, password for admin is `exploreradminpw`, not `exploreradminpwd`. Please make sure that for just in case you're using incorrect password.

Orderer need not to be specified in your connection profile. It's retrieved via Service Discovery. Could you provide more detail about `different orderer`?
Can I override the settings and tell explorer to read the orderer from the connection profile. I don't which orderer it is reading, maybe old one.

*[2020-09-09T05:25:14.822] [ERROR] FabricConfig - Not found signedCert configuration* Can you doule check this?
yes
tried from every possible way but failed
Can you share your masked connection profile?
tt.txt
I don't see any *signcerts* in organization section? Please refer to https://github.com/hyperledger/blockchain-explorer/blob/master/examples/net1/connection-profile/first-network.json#L45

I've tried with signcerts as well but still faled
The certificate authority mentioned in the orgs is not present in the connection profile. Moreover the paths you provided should not direct to your local filesystem, it should direct to docker mounted volumes. I highly recommend you to go through this https://github.com/hyperledger/blockchain-explorer/blob/master/README.md

@nekia Q2. Can I increase the discovery timeout which is by default 3000 from config file?

Q1 No you can't. The list on Explorer completely depends on the result from service discovery. You can see the result by executing discover CLI by yourself.
https://hyperledger-fabric.readthedocs.io/en/release-2.2/discovery-cli.html
Q2 No you can't. If you're mentioning the timeout on your log, I think it depends on the settings of grpc. You might be able to override it by connection profile.
```
"peers": {
"peer0.org1.example.com": {
"url": "grpcs://localhost:7051",
"grpcOptions": {
"ssl-target-name-override": "peer0.org1.example.com"
}
```

running perfectly with old version but when trying to run same with latest one through containers, I got error
It seems that your connection profile is incorrect. You're specifying cert file with path of host side, not one of container.

help me please
In the last snapshot, I can see `localhost` in url of `peer0.shippe...`. It's incorrect. You need to specify a hostname which is valid in your docker network (it's probably `my-network_byfn`, I guess). It's worthwhile to use the utility @saanvijay suggestes

now this
Please check log and make sure Explorer container belongs to the same docker network with your fabric network `docker network inspect [your network]`
Thanks, I solve the issue
I think there is some issue with newer versions, so I go for 1.0.0
It works fine in both ways
Great, Is it possible to share what kind of issue you have with which version?
I faced wallet path issues with all versions greater then 1.1.0 but works perfectly same paths in 1.0.0
I see, if you have already had existing wallet generated by the previous Explorer, you need to migrate it to new format as mentioned below.
https://hyperledger.github.io/fabric-sdk-node/release-2.2/tutorial-migration.html

https://hyperledger.github.io/fabric-sdk-node/release-2.2/tutorial-migration.html
will look into it but I'm using container which means every version has it's own image and new container created everytime. The path I'm assigned is same as mentioned in documentation
I'm using fabric 1.4.4
Hi All,
Do we have any fab token example using Java SDK?if we have please can you share with me.

@nekia hi, need i configure the `tlsCACerts` with `path`? i configured with `pem`, and it prompted an error:

Hi All,
Can we design a utility token using hyperledger fabric without fab token? If we can do please can you share me the existing ways to do.

So I'm not sure of the best way to communicate this, but I've found an oddity with the transaction timestamps in the code of SyncService.js. It seems that the timestamp of the first transaction in the block is assigned to **all** transactions in that block. In l.486 the block timestamp is defined as the timestamp of the first tx in the block, and thereafter this variable is reused for **every tx** in the for loop starting in l. 503. It is finally committed to the database in l.631. However, each transaction actually has a unique timestamp that differs based on when it was created. See the following example for block 177 in my test blockchain, which was created by adding some logging output to SyncService.js:

@bh4rtp Attached connection-profile example with the CA configuration. Please follow the same configurations.
@jeevasang appreciate your example.
it seems to me explorer count nodes only by IP address or hostname, it wont care about the ports, that results in containers running on same host to be counted as one node.
where can I file a bug?
https://jira.hyperledger.org/
What are the URLs of your nodes? For me it's working fine using a local test network set up with Docker
@sigma67 just a second. let me pull the profile file and paste it here.
here is the profile
```grpcs://192.168.56.32:7004
```
the file is too big for rocket chat
that is just one of the peer node.
others look similar, the only difference is the port.

everything still works but on the dashboard, it should have been 4 nodes, but shows just 1 node with the IP address.

Thank you for reporting issue @tongli
Explorer assumes that all peers are running as container on guest OS when `DISCOVERY_AS_LOCALHOST` is set to `true` and `localhost` is assigned across all peers.
Explorer assumes that all peers are running as container on local Docker host when `DISCOVERY_AS_LOCALHOST` is set to `true` and `localhost` is assigned across all peers.
Explorer assumes that all peers are running as container on local Docker host when `DISCOVERY_AS_LOCALHOST` is set to `true` and `localhost` is assigned across all peers as `fabric-samples/test-network` is.
it seems that explorer only accepts path configuration of tlsCACerts.
Otherwise, Explorer will count all peers which have different port with same IP address (except 127.0.0.1, localhost) as a single peer.
pem format is also supported by Explorer in v1.1.1 or later. FYI
i just changed all pem to path for ca profile, otherwise it reports path not configured.
1.1.2 is used.
@nekia is there an example of connection profile for fabric-ca? i still can not get explorer running for ca.
This conversion happens inside fabric-sdk-node.

This address mapping between localhost:port and each url happens inside fabric-sdk-node.
[fabric-network gateway.connect DiscoveryOption settings](https://hyperledger.github.io/fabric-sdk-node/release-2.2/tutorial-discovery-fabric-network.html)
We don't have example for that in our tutorial yet
But there are some connection profiles used for our end-to-end test environment
https://github.com/hyperledger/blockchain-explorer/blob/master/app/platform/fabric/e2e-test/configs/connection-profile/org1-network.json
We might need more examples for fabric CA enabled fabric network.

@nekia, hooked up with explorer works only when I do not use ca. When ca is configured, it won’t work. Any idea what is significant configuration parameter to watch to make explorer also work with ca node so that user management function can work?

Kubernetes
*Explorer Block syncing Issue with Kubernetes setup*
*Current Configuration: * We are using latest version of explorer and version of fabric is 1.4.2 with private data collection. In network configuration, We have 3 channel network setup with 4 organization in each channel and some of them are common among them. We have created one explorer profile of an organization which is part of all the channels.
*Issue:* Explorer works fine for few hours of its deployment in Kubernetes but after some time dashboard, blocks and transactions are not getting updated with the blockchain network. We have also observed that in network page ledger height is getting updated all the time but other than this nothing is getting updated. But redeploying the pods of explorer help us getting everything into sync again for some time.
@tongli User management function doesn't require fabric ca configuration. Identities for additional users except admin have been managed with ID/PASSWORD manner.
The configurations mentioned in the following page are mandatory to make use of fabric ca in Explorer.
https://github.com/hyperledger/blockchain-explorer/blob/master/README-CONFIG.md#using-fabric-ca
@nekia so the user registration function of explorer is really just a function to register a user to use Explorer, these users have nothing to do with Fabric network itself or any CA node, is that correct?
this bug has been filed for awhile, no activity at all.
https://jira.hyperledger.org/browse/BE-829?filter=-2
can someone please take a look at this?
I don't think Explorer is meant to manage fabric-ca users, that's probably more within the scope of the Cello project (monitoring vs. managing/operating)
Ofc it would be great to have both in one app, but right now they're two distinct projects with different goals
It seems it's actually part of the project, but still in design phase: https://github.com/hyperledger/cello/issues/118 -> #cello
Yes, that's correct.
I left a comment, Explorer expects that peer has been assigned 127.0.0.1 in such an environment each peer is running as a container on the same host machine with Explorer.
Is it acceptable for you to change IP address?
@nekia, not really. It could be a multi host env.
For example, some nodes run on one machine and some run on other machines. Ports are important part of running app, explorer should not make assumption like that.
OK, I understand. We'll look into it.

Hello all!
Can explorer manage the different views of different users, if they are using different private data collections?
In other words, can I choose between users from different orgs and see the blocks from the different channels that organization has access to?

Explorer doesn't support private data collections.
No, Explorer can't do that. Explorer doesn't support private data collections.
Explorer has own user management which is nothing to do with user identity on fabric network.
But we're working on adding ACL to our user management based on the configuration of network.
But we're working on adding access control list which is based on the configuration of network to our user management.

Hi @nekia , I have 567 blocks in my system and also on further analyzing this I have observed that sync.js process stops running after few hours of fabric network being in idle state.

I can't recreate the issue on my local fabric network where has 5000+ blocks.

How to register new user in hyperledger explorer?
Screenshot from 2020-09-29 14-36-17.png
Why it shows 1 peer multiples times?
Thanks :)
i cannot register new user either.
You seem to be using old version of Explorer. You need to use the latest version which enabled user management feature.
Which version of Explorer are you using?
Hi @nekia ,
On further investigation, I have observed that the issue is when I have memory crunch. Previously, my observation was that it was occurring after some idle time but its happening when I am left with lesser RAM(100MB-200MB).

Two comments regarding the typescript migration:
1) typescript is not yet a dependency and
2) it seems the "npm run build" needs to be added to the main.sh install script, so it runs the necessary Typescript compilation
After I did those 2 steps it worked for me :)

You're right. Thanks. We'll update it later on. Currently user needs to do like that or do command like `npm run start`.

Hi, hyperledger-explorer support fabric 2.0
hi every one.
I am using Explorer v1.1.3 containerized with Fabric 1.4.7 and it is my view:
1- users need to have the ability to change their passwords.
2- sometimes Explorer doesn't work properly although has no error log. (it only shows peer nodes and need to restart the container multiple times to works properly)
3- explorer should works without having channel section in its connection.json and should collects channel information by itself.
4- the chaincode section is not working properly. (chaincode instantiated on channel "a" also is shown in channel "b")

Regarding 2), there are definitely error logs available in the `logs` folder

```error: [ServiceEndpoint]: Error: Failed to connect before the deadline on Committer- name: org1.orderer:7050, url:grpcs://org1.orderer:7050, connected:false, connectAttempted:true```
that means it can't connect to the orderer; I ping the orderer from the explorer container and it is ok!
do you have any idea how I can fix it?

3) I believe fabric-sdk-node which explorer deeply depends on has a requirement specifying at least 1 channel in connection profile.
4) are you using different chaincode for each channel?
Do you configure all 4 required settings, in particular affiliation, in your connection profile?

Hey I have been experiencing some weird issues with hyperledger fabric explorer
the peer is configured with mTLS
explorer side iam able to configure mTLS setting and for initial 10 requests seems ok peer is responding for discovery calls and endorser calls
suddenly after sometime TLS handshake issues are popping up
seems like mTLS functionality is not implemented properly in the explorer side
Any explorer maintainers here ?

As you can see in the log, Explorer can't find crypto artifacts. It seems to be a miss configuration of your connection profile and/or docker-compose.yaml. Please make sure that the path to crypto artifacts in connection profile align with the path to the volume you mounted for crypto via docker-compose.yaml.

Thanks. Can you make sure that ping from explorer container to `peer0.manufacturer.tracktrace.com` container is working correctly? I know you did it for `manufacturerpeer0` last time.
both are aliases
able to ping with both the names as well as i tried with direct ip to ping the peer0 container...
which is working
but explorer is not working
Ok, thanks.
Can you make sure peer0 is listening on 7051 port?
yes it is running on 7051 port ...am connecting rest api on the same port .. if u have any command to show u ... it is running on 7051 port

No, there is no way retrieving PDC from explorer.
Sorry for inconvenience. Please add more environment values to your docker-compose.yaml to retrieve log regarding `grpc`.

There seem to be a certificate issue. Please make sure that the certificate is referable correctly on the Explorer container. @rohithkumar
refering the same certificate which generated for fabric...and the certificate is also placed in the correct path....
I think you need to rebuild the docker images with the latest changes in git.. so that this certificate checking version is backward compatible
What version of cryptogen are you using when creating your crypto artifacts?
am using 1.4.4 fabric... might be there is mis configuration of cryptogen
what version do explorer supports
i cant change certificates of fabric now for explorer
https://jira.hyperledger.org/browse/BE-768?focusedCommentId=69657&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#comment-69657
The same issue has already been reported.
yes..but do the fix is updated in the docker image of 1.1.3
Clipboard - November 1, 2020 7:02 PM
do my understanding right?
The solution for the issue BE-768 I pointed above is updating cryptogen tool to v1.4.0 or later.
I guess the issue you're facing now is nothing to do with the recent changes.
it should be backward compatible... when fabric is running with backward compatible certificates...
it's a compatibility issue of node.js. In Node.js v10 or later, version of openssl seems to be updated to v1.1.
ok then i need to regenerate the certificates using latest cryptogen and try for explorer?
Old format of certificate generated by old cryptgen is not allowed in openssl v1.1 or later.
Yes
ok will try
thanks for the support and will come back if i face any issues

Dear all,
I have a doubt regarding the *minimum system requirements for hyperledger explorer*.
I am using a system with 4GB RAM and 80 GB SSD.
I am using the hyperledger explorer docker images with tag 1.1.2
*When I run the _top_ command* , I see a process with random name consuming 197% of CPU and 60% of memory (https://user-images.githubusercontent.com/30879156/97715100-46477d80-1ac2-11eb-92a3-a121e512d81e.png)
*output of _docker stats_: *shows hyperleger explorer db service is consuming 197 % of CPU and 60% of memory (https://user-images.githubusercontent.com/30879156/97715625-ebfaec80-1ac2-11eb-993c-2e5c15b391ed.png)
I am not sure whether that random process is linked with hyperledger_explorer_db container.
If I remove the hyperledger explorer services, the random process disappears and CPU utilization and memory becomes normal .
I initially thought my system was under DDoS Trojan attacks as specified here https://admin-ahead.com/forum/server-security-hardening/unix-trojan-ddos_xor-1-chinese-chicken-multiplatform-dos-botnets-trojan/
But now i doubt that the random process is linked with hyperledger explorer db.
Why hyperledger explorer db docker container is starting a random process in the host machine and consumes 190 % of CPU and 60 % memory. ?
I would require help for the following questions :
- Does anyone have experienced this behavior when using hyperledger explorer ?
- Is this a normal behaviour of hyperledger explorer db docker services to consume this much CPU and memory ?
- What is the minimum system requirements to run hyperledger explorer docker services
Thanks & regards,
Anand

Hi everyone! Does anybody know how to deny a user from seeing the content of other users ?

Hi @Vgkmanju First, I recommend you using the latest explorer container image (1.1.3). And the log you shared seems to be nothing to do with Explorer runtime log. I guess it's like a log while building a docker container image, but I'm not sure.
In that case, you don't need to specify/override command for Explorer container. And also need to update your connection profile which is consumed by Explorer to the new syntax. Please refer [here](https://github.com/hyperledger/blockchain-explorer/blob/master/README-CONFIG.md) for the detail.

Hi @nike It seems to be kind of network issue that is reported in the following JIRA of fabric-sdk-node.
https://jira.hyperledger.org/browse/FABN-1646
This error is incurred sometime when multiple transaction are raced. So far this error doesn't give any major effects to Explorer.
The fix of this issue has already been introduced into the latest fabric-network package, but it's introduced another issue as below.
https://jira.hyperledger.org/browse/FABN-1663?jql=project%20%3D%20FABN%20AND%20text%20~%20%22system%20chaincode%22
The fix of this issue has already been introduced into the latest fabric-network package, but it's introduced another issue as below.
https://jira.hyperledger.org/browse/FABN-1663
So we have to wait for the next release 2.2.4.

Hi guys,
We're trying to run hlf explorer instance in k8s on a network with 10-15 organizations each having its own explorer.
Explorer looses a connection to a peer sometimes and outputs an error. It leads to outdated data is shown in the explorer.
https://lists.hyperledger.org/g/fabric/topic/hlf_explorer_fails_to_connect/78529682?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,78529682
Can anyone suggest how to overcome this?

Also, maybe worth mentioning that we're experiencing "Context deadline exceeded" issues sometimes. https://lists.hyperledger.org/g/fabric/topic/context_deadline_exceeded/78529438?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,0,78529438

Can you please make sure that your Explorer image is using fabric-network 2.2.4-snapshot.7 by checking package-lock.json on the Explorer container? The error should have been resolved in the latest fabric-network package.

Hi, all :)
Hi, all :) when can explorer suppport centos? Thanks a lot!
Thanks @CaJIbHuK It seems that the fix for fabric-sdk-node for FABN-1663 is not enough yet.
Thanks @CaJIbHuK It seems that the fix of fabric-sdk-node for FABN-1663 is not enough yet.
I've shared it to the community.
https://chat.hyperledger.org/channel/fabric-sdk-node?msg=6C4q27B7d6JBgKApJ
Hi @Suki You mean if Explorer can run on centos? I've never tried that, but I think Explorer can run on centos too.
Got it, thanks!
get it. Thank u!:grinning:
Are you using fabric 1.4.x ? @CaJIbHuK If so, I could recreate same issue on my local, too. This is caused by uncaught error on Explorer. The latest snapshot of SDK (2.2.4-snapshot.7) is working expectedly.
No, we are using fabric 2.2
We'll fix this issue.
Oh, ok. Anyway we found an issue on Explorer, we'll fix it
Or the peer that this error incurred on has no chaincode installed?
I've just checked again, because yesterday `discover peers` command gave the following result.
```

But now it gives:

I've restarted all the peers, and `_lifecycle` appeared on all of them. Maybe you know why it may happen?
But unfortunately, now the previous error reproduces again

Anyway, thank you for your help, will continue my investigation
I have been using explorer docker images for awhile, should work without issues.
OK, Thank you too. FYI The following options might get you helped for debugging.

Hello everyone!
I'm trying to integrate explorer with Oath the google, someone has a documentation reference for working?
I apologize for my English it is not my native language.
Has joined the channel.
Has anyone tried Explorer v1.1.3 with Fabric 2.3.0? The release notes says v1.1.3 supports Fabric 1.4.0 - 2.2.0. I'm trying to get Explorer v1.1.3 working with Fabric 2.3.0. I've mTLS enabled in the Fabric network and I've set client.clientTlsIdentity in the Explorer connection-profile. The initial connections with the peer works. But after a while I find Explorer generating a self-signed certificate to make the connection, and all the subsequent connections after this fails.
yes. v1.1.3 does support fabric 2.3.0.
Thanks for the confirmation. Would you be able to help me point me to where I can get help in resolving this issue?```
The initial connects with the Peer works just fine. Like:``````
```

But after a while it fails as Explorer is creating a self-signed certificate even though I've given client.clientTlsIdentity in my connection-profile.

``` ```
I see the below error in Peer (it seems Explorer isn't even providing a client certificate):
``` ```

it seems to be certificate error. you can check the connection-profile, I think you used the wrong tls certificates.

v1.1.3 has above issue for mTLS. It's fixed in the latest master. Can you use the container image locally rebuilt instead? @chanjaljayaram
Thanks Nekia... I was finally able to get it working with the below updates:```
1) I was missing the setting of DISCOVERY_AS_LOCALHOST to false
``` ```
2) in FabricGateway.js I see the client.setTlsClientCertAndKey() being called. I changed it to client.setTlsClientCertAndKey(channel.client._tls_mutual.clientCert,channel.client._tls_mutual.clientKey);
``` ```
Is that the fix in the master branch?

I'm getting the same error... does the change need to be done in the ".js" files as well?
Nekia, I did similar updates to what you did in FabricConfig.ts and FabricGateway.ts to FabricConfig.js and FabricGateway.js... it is working fine for me now... Thank you very much

So you have `peers` entry in organisation section in your connection profile as below?

Hi All!I have a Hyperledger
Hi All!
I have a Hyperledger Fabric network in which mutual TLS is enabled on the peers and orderers.
I want to connect Hyperledger Explorer to this network.
Can anyone help me with what configuration needs to be added for mutual TLS in config.json or connection.json for Hyperledger Explorer ?
Thanks!
logs.txt
@nekia Hi! Sorry for being silent for so long! I tried to set those environment variables. I've attached the hlf-explorer logs.
As I said previously, the number of connections explorer tries to make to the corresponding peer correlates with the numberr of blocks fetched. All these connections are identical. Some of them fail to establish due to timeout and the corresponding exception is raised. I assume, that when exception is raised, syncing process interrupts and never recovers.
The sample network has 14 orgs each of which has 1 peer.
Hi everyone, I'm trying to configure hyperledger explorer with a local blokchain network instance created using ibm blockchain platform extension
The tutorial on https://github.com/hyperledger/blockchain-explorer

but there is no information of where to find this information in docker containers already created
could anyone please give me some directions on how to threat this case?

I've never used IBM blockchain platform extension. You have probably better to ask the community of the platform how to retrieve credentials in the environment.
You seem to be failing to retrieve channel list from peer node. Can you share the entire log of Explorer?
You need to follow the steps as below to use Explorer with fabric CA.

Can you share your connection profile?
Hi, question regarding the peersStatus API endpoint
It seems the status Variable is always set to DOWN no matter what
https://github.com/hyperledger/blockchain-explorer/blob/8b8ddc65ca6e4a9117ba401251529335d633169e/app/platform/fabric/Proxy.ts#L125-L149
Is this an oversight/work in progress or am I missing something?
Has joined the channel.
the postgres of explorer has only been tested on ubuntu and MacOS, so other distros are not necessarily supposed to work, correct?
Correct. If using explorer-db container
Correct. If you use [explorer-db container](https://hub.docker.com/r/hyperledger/explorer-db) instead, it will work regardless your distros.
Sorry for confusion. Currently Explorer is not using the status internally. It's should be obsoleted from `peersStatus` API.

Hello Team,
Am trying to set up explorer with a non-admin role user wallet, so for the "enrollUserIdentity" section am passing the certificate and private key of a non-admin user
But it fails at the discovery phase stating

Can someone please suggest what additional step is needed here?

I am trying to configure HyperLedger Explorer v1.1.3 (Sep 28, 2020) to point to an existing IBM Blockchain Platform (simple 1 Org network). Does anyone in this channel has a config tips / guide to point to the IBM cloud (instead of the local test network)?
For example:
a) config to point to a local fabric test network: https://github.com/hyperledger/blockchain-explorer
b) config to point to IBM Blockchain Platform cloud ==> adjustments to config.json etc required / other tips?
Thank you.

Please refer the case that Explorer is running as a container. In this case, in your connection profile, you need to specify a peer with URL which is directly reachable from Explorer container.
https://github.com/hyperledger/blockchain-explorer/blob/master/examples/net1/connection-profile/first-network.json
https://github.com/hyperledger/blockchain-explorer/blob/master/README-CONFIG.md#run-hyperledger-explorer-using-docker-compose
Explorer requires admin privilege to query chaincode info to fabric network.
And Fabric network uses `Node OU` to confer a role onto an identity.
This convention allows you to distinguish MSP roles by the OU present in the CommonName attribute of the X509 certificate.
This error is saying that node ou for `admin` is undefined. Please make sure that Node OU is enabled in your each `config.yaml` ex. `crypto-artifacts/**/msp/config.yaml`
https://hyperledger-fabric.readthedocs.io/en/release-2.2/membership/membership.html#node-ou-roles-and-msps
Ok, thanks for the reply :)
Is it just me or are CONFIG transactions always missing the txhash? It seems it is not being returned by the Fabric Node SDK
Is it just me or are CONFIG transactions always missing the txhash? It seems it is not being returned by the Fabric Node SDK.
It seems other important data is missing as well, such as previous/current config. The colums read_set, write_set, chaincode_proposal_input, tx_response are all empty

Edit: I created an issue on JIRA
for the sample network is it 'first-network' or 'test-network'? some github documentation seems to not have been updated since the days of byfn.

Hi everyone, I want to avoid any Single Point of Failure by providing multiple peers to my explorer. I have specified multiple peers in my connection-profile.json and the explorer is working but if the first peer in the connection-profile list is unreachable, the explorer does not get the required infos from other peers. Is it a normal behaviour ? If not how can I fix my issue please. (only network topology informations are not present, block and transactions infos are still present)

(only network topology informations are not present, block and transactions infos are still present so I tried to declare each peer as an anchor peer to be able to execute serviceDiscovery but it did not solve my issue)
my test also fails for the single point of failure.
ok thanks, is it related to the last tag version or it was always the case ?
I remember 1.4 sdk can specify endorsing peers
I remember 1.4 sdk can specify endorsing peers. 2.2 uses discovery to find endorsing peer according to endorsing policies automatically. It may be a bug which has been already reported on JIRA.

Hello good morning!
I'm working with hyperledger-blockchain-explorer 1.1.3.
I can visualize the dynamics of the network correctly but I need to make some visual changes such as color and some images (I don't have much experience in this field), could you help me with this ?, the implementation was done using docker.

hello all, I have a (probably) very stupid question. how is it possible to build a link that points directly to a specific transaction in hyperledger explorer (obviously after you have logged in) ?
Hello, we had same request from the community before.
https://jira.hyperledger.org/browse/BE-694
Yes, we need to consider authentication before providing that kind of info.
Hi, can I ask you to give me some more detail about the steps you followed?
Great to hear :)
thank you, it is exactly the feature I was describing.

Hi all, hope everyone is safe!!! . I am having a weird issue with login and password with hyperledger explorer where the username and password set in the env variables for container is not being accepted. I also tried changing the username and password from default but explorer front end stops working. There seems to be issue with the server logic for username and password
Hello, I have a question/issue: I deploy the explorer via Kubernetes and connect via ingress. On any browser other than safari I have no issue with the explorer, but on Safari, after login, I have a blank page and the following error in the console of the browser:
[Error] Refused to connect to wss://MYURL because it appears in neither the connect-src directive nor the default-src directive of the Content Security Policy. (x2)
Do you have an idea if it's an issue with the explorer or with my ingress config? Is it some kind of cors issue?
Thanks a lot!

Hi!
Good afternoon,
I'm Mario, I live in Salvador / Bahia / Brazil. I am master in mechatronics at Universidade Federal da Bahia.
I have a doubt. I'm following the entire script on https://github.com/hyperledger/blockchain-explorer, but I can't access localhost. The terminal has the following error:
Compiled successfully!
You can now view hyperledger-explorer-client in the browser.
Local: http://localhost:3000
On Your Network: http://192.168.15.83:3000
Note that the development build is not optimized.
To create a production build, use npm run build.

What do I do? I did not find a solution in the forums. Thank you very much in advance.
The development build is a bit tricky to get working at the start, since it uses port 3000 instead of 8080, which HL Explorer is configured to use by default
I recommend doing a npm build first to try it out and run as described in instructions
If you really want to run the development build you can check our fork at https://github.com/sigma67/hypersec, we got it working
Pretty much you need to tell the frontend to use server port 3000 instead of 8080 and it should work fine
Thank you friend! Do you have a script to make this compilation? correcting port 3000 to port 8000?
Thank you so much! Do you have a script to make this compilation? correcting port 3000 to port 8000?
what is the package.json folder? Is the folder inside the explorer folder?
Additional configuration: you must set the proxy parameter in package.json to point to the Hyperledger Explorer backend. localhost: 8080 works well if the client is running on the same host.
I didn't find packge.jon
package.json is a file in the client folder

Hi,
I see that the Explorer documentation mentions some authentication possibilities: https://github.com/hyperledger/blockchain-explorer/blob/main/README-CONFIG.md
But currently we are interested in the possibility of managing authentication with Keycloak. Have anyone tried or succeeded in this operation?
As far as I know, we've not tried it yet. Explorer is using passport.js middleware to authenticate users accessing to the dashboard. So if you use the following middleware on the top of it, you might be able to do that kind of implementation.
https://github.com/louie007/passport-keycloak-oauth2-oidc
OK, thanks, we will try this

Hello everyone, I have followed the quickstart (using docker) to start explorer. Everything works fine but when I try to access the ui via localhost:8080 the server doesn't load. Both explorer and explorer-db images are running but still it doesn't work.
Could you please check the logs of explorer and explorer db??
also if you have hosted it on cloud make sure you have access to that port

@nekia Have you had a chance to investigate this? Using the latest fabric peer version 2.3.1 and the latest explorer version 1.1.4
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=hNxiB5GXPxpbBo4NP) I have found docker env *SSL_ENABLED* and *SSL_CERTS_PATH* now, I am getting error /opt/explorer/app/main.js:157
server.on('connection', connection => {
^
TypeError: Cannot read property 'on' of undefined
Did some digging, the offending line is here: https://github.com/hyperledger/blockchain-explorer/blob/main/app/platform/fabric/sync/SyncService.ts#L605
on the transaction that's causing the crash, `txObj.payload.data.last_update` is an empty object.
I'm working on it. I could reproduce this issue with fabric v2.3. Currently explorer doesn't support v2.3. I'll have a look at adding the support.
We've fixed it in the latest codebase. Probably a new release will be created in the end of this week.
@anilkumargr Thank you for your recent change regarding direct link to TX detail. That's great. https://jira.hyperledger.org/browse/BE-694

Hi @nekia , I have deployed Hyperledger explorer v1.1.4 in docker environment with fabric 2.1. after every 2,3 days, My explorer stops working. I have checked the logs `

Hi cmhacker, I'm facing the same problem. There is an issue in Jira about that
https://jira.hyperledger.org/browse/BE-855
Hi Nekia, I have made the required changes to display the direct link in the TX detail modal. However, I did not use the share icon as I did not see it fitting into the modal and it did not seem to be consistent with other things on the modal.
I have created a pull request Be 870 display direct trans link #237. Could you please review and approve the pull request.
I've been trying to fix it but I don't know the best way to do it. I discover a way to mantain sync process running. But is ugly, basically I commented the lines `shutDown();` from `app/sync.ts`
Has joined the channel.
Hi @nekia , Is it possible to setup explorer in OCP?
Hi Team, Is it possible to setup explorer in OCP?
Thanks @anilkumargr for adding the direct link.
I'm not sure if it's possible. But I've seen someone who make explorer run on Kubernetes, so I think it's possible to setup Explorer on OCP as well.
Thanks @nekia

Hi All,
I am trying to use Hyperledger explorer.
I have well configure it and it is working.
However, it does not take into consideration the new transaction.
I want to configure it in order to have a real time behavior.
could you help me to realize this

Hello! I am collaborating on the Fabric-Private-Chaincode stream and we would like to use Blockchain Explorer to easily show how transactions are stored using FPC. We would like to be able to also show the chaincode function and arguments that are sent (they should be encrypted). I am not sure where I would have to modify to add these fields. Any pointers are appreciated!
Hyperledger Explorer uses the channel subscriptions provided by fabric-node-sdk. Your data should be somewhere in the transaction data provided by the channel subscription. I'd start by checking if the rw-sets of your transactions are being synced to HL Explorer's database
thank you for replying. I did find that in the sync service blockchain-explorer/app/platform/fabric/sync/SyncService.ts they are obtaining the info I would like to display `chaincode_proposal_input =
txObj.payload.data.actions[0].payload.chaincode_proposal_payload.input
.chaincode_spec.input.args;` what I don´t know is where that field should be displayed ...
I think you need to modify `client/src/components/View/TransactionView.js` and `app/persistence/fabric/CRUDService.ts`. In `CRUDService.ts`, `chaincode_proposal_input` field is currently filtered from API response.
[blockchain-explorer/CRUDService.ts at main · hyperledger/blockchain-explorer](https://github.com/hyperledger/blockchain-explorer/blob/main/app/persistence/fabric/CRUDService.ts#L49)
aaaahhhhh ok, and I wouldn't be able to do that inside the docker environment correct? I would have to clone the repository, modify and then build everything, right?
That's right.
Explorer v1.1.6 has been released!

Hi everyone.
I noticed when I add *peer* from another organization in my network and join it to channel, it *doesn't have* installed *_lifecycle* chaincode (1*) and that's the reason why *explorer*, deployed for this organization is *failed*.
I found a workaround for it - to approve some chaincode, it could be even not being packed and installed, like
`peer lifecycle chaincode approveformyorg --name randomchaincodename --package-id 1 --tls --tlsRootCertFiles {path_here} --cafile {path_here} --version 1 --channelID defaultchannel --sequence 1`. I executed it from initial peer of first organization. Somehow it forced new peer to install _livecycle chaincode (2*) and than explorer could start.
```
1*. Right after join new peer to channel on discovery request

Thank you for your feedback and we'll have a look at it. First it seems to be necessary to assume it returns empty.
Thanks for the reply @nekia. I also think that check should be performed on explorer's side, but don't you know is that OK that peer doesn't have _lifecycle chaincode installed initially, right after joining channel?
Hello. Got another bug with explorer. When I'm trying to start it, it stuck. Here the last logs from container:

I added probes to k8s deployment with looking into logs/app.log for some errors, and restart if exist, but these `<<<<<<<<<<<<<<<<<<<<<<<<<< Explorer Error >>>>>>>>>>>>>>>>>>>>>` records don't appear in logs/app.log.
In case if I restart node manually, it works good after restart.
Is any way to detect such errors?
Peer 2.2.0, Explorer 1.1.6
can v1.1.5 be upgraded to v1.1.6 without any changes of configuration for fabric 2.3 network?
or is there any documentation about the upgrade?
Does adding pipe to `CMD` in Dockerfile could solve this issue with leaking logs?
```
https://github.com/hyperledger/blockchain-explorer/blob/main/Dockerfile
...
# run blockchain explorer main app
CMD npm run app-start > /opt/explorer/logs/node.log && tail -f /dev/null
```
@nekia could you please advise something with it?
an update: that's related to case when chain have a lot of config blocks. no such problems with fresh networks

I need some way to detect if explorer is unhealthy. Through logs (doesn't work correctly now) or through some GET /status to http server.
[ ](https://chat.hyperledger.org/channel/hyperledger-explorer?msg=HcW4JTjLfuMRf9KR6) Implemented it. It works, but after such hack there are empty logs if I want to check smth by `kubectl logs {pod_name}`. It doesn't fit to me

Yes, it can.
If you add liveness probe with `httpGet` to `localhost:8080/auth/networklist`, you are probably able to detect unhealthy of explorer node.
Thanks @nekia! I'll try :ok_hand:
@nekia will it detect if last synchronization attempt was failed or it just shows that at least one sync was done successful?
I think it will just indicate if explorer (backend) is healthy or not.
Ok, got it, thanks!
Hey @nekia,
I found 2 issues when spinning up a new explorer on a network with multiple blocks that I would like to share.
1. Explorer is making multiple `sendDiscoveryRequest` calls, 1 per block. Which retrieves the same information.
What are your thoughts on calling it only once during the initialization phase instead of calling it on every block?
After the DB is synced, call it once every block like how it's done currently.
2. fabricGateway.queryChainInfo error crashes the explorer. What do you think of adding a try-catch re-query flow here?
```

2. I think we should handle this error within synchBlocks method in SyncService.ts rather than adding re-query within queryChainInfo, because we can expect re-query in the next sync process. Your thought?
Yes, I think, we can remove it.
Hi @nekia, i've created a PR to fix 2 issues:
1. discovery error causing an endless loop.
2. timeout error on getChannelInfo crashing the explorer.
Please take a look :pray:

Hi, can you see any errors in logs? `logs/{app,console,db}` or `docker logs explorer`
Has joined the channel.
hi, how can I configure discovery for multiple channels? I have:
```
"channels": {
"channel-1": {
"peers": {
"peer0.org4.example.com": {}
}
},
"channel-2": {
"peers": {
"peer0.org4.example.com": {}
}
}
},
```
But I'm not receiving information from the second channel:

In the above log, you can see how it's sending the same discovery requests even when the channel-name is different
Has joined the channel.
Are you working on code change for `stopping meaningless discovery request during initial syncup phase`? If not, I will.
Thank you for sharing issue. I'll try to recreate it on my laptop.
https://jira.hyperledger.org/browse/BE-877
@nekia Peer name is displayed as Request URL.
@nekia Peer name is displayed the same as Request URL, is this a bug?

Thank you for sharing.
It seems to be caused by insufficient privilege of identity you specified in connection profile. There are 2 options. Recently we changed it the code around this implementation. So if you use the latest codebase and build your own image on your local, it'll be resolved. The other one is to wait for the next release which is scheduled this weekend.
`./build_docker_image.sh` will generate new images (explorer / explorer-db)

Hi, I was trying to build explorer locally, but ran into issues. I followed the read me and used nvm to install node 14.13.1. However when I run `npm start`, I get no logs around which ports the node server is using:

Explorer v1.1.7 has been released!
hi @nekia , as 1.1.7 is releases, to update the images for a running explorer, can i directly use `docker service update --image` with existed `walletstore` and `pgdata` volumes?

Sorry we miss that part in the current version of README. We'll fix it. Can you get access to `http://localhost:8080` ?
Hi @nekia, I'm using HFv2.3.1 and explorer v1.1.6 on kubernetes/minikube setup. I have few doubts on explorerdb,
1. Let's suppose number of blocks on the channel are in millions and then if we redeploy the explorer and explorerDb pod, will there be any outage while fetching all the block details to make the explorer up and running again?
2. Is it possible to use AWS RDS PostgresDB to persist the data. Is it the best practice for explorerDB?
3. When we redeploy explorer, will it start fetching details from genesis block or it will get the last block from explorerDb and start from there?

hello guys! anyone know a solution to this problem?
couldnt find a solution by googling
I Think your problem is in the docker-compose.yaml file, specifically in this section```volumes:
- /"REAL PATH TO THE FILE"/blockchain-explorer/config.json:/opt/explorer/app/platform/fabric/config.json
- /"REAL PATH TO THE DIRECTORY"/blockchain-explorer/connection-profile:/opt/explorer/app/platform/fabric/connection-profile
- /"REAL PATH TO THE DIRECTORY"/fabric-samples/test-network/organizations:/tmp/crypto
- walletstore:/opt/explorer/wallet``````
In my case I replaced REAL PATH with ```/Users/xxx/go/src/github.com/hyperledger-labs/fabric-private-chaincode/samples/deployment/test-network```
```

Hello guys!
Hello guys! I'm trying to run a simple integration example between Fabric and Explorer, which can be found on this tutorial: https://medium.com/coinmonks/blockchain-explorer-integration-with-hyperledger-fabric-fc14570753f7. Besides this tutorial, I followed all the steps explained on blockchain-explorer repository (https://github.com/hyperledger/blockchain-explorer), using the codebase tutorial for that (instead of the docker one). Even though I did everything that I was supposed to do, I couldn't run the explorer. I don't know if the port would be the problem (as I can't access http://localhost:8080/ after running ./start.sh) or if I still have some steps to follow to fix it. I also took some print screens to show the logs and the paths configured, that are shown below. I'd really appreciate if someone could help me. Thanks!

Could anyone help me?
In your `connection-profile.json`, you have configured incorrect path for adminPrivateKey. You need to specify valid path on the `explorer` container which start with `/tmp/crypto/...`, not on host machine which start with `/home/gavimat/...`.

I manage to find what I was doing wrong by starting all over again and again, following the steps mentioned on Hyperledger Explorer GitHub repository... and it was a silly mistake: the name of the network I was working with wasn't as I thought. By running "docker network ls" command I realized that I had named it as "artifacts_test".
Anyway, I'd like to thank you for your attention and help!
I found a video on Youtube that helped me to configure the files needed. This video can be found in the link below:

Hi, I am planning to deploy a HLF environment on Raspberry Pi and I was curious if anyone tried to create a Hyperledger Explorer docker image compatible with ARM64 devices. Any links to existing images or instructions on how to do that would be greatly appreciated, thanks!

Hi guys! I am trying to run Hyperledger Explorer on my local machine. When using the docker quick start, I am able to run it smoothly, however when using the codebase quick start, the node server doesn't seem to start, although I have successfully created the DB, build the app, use the correct dependencies, etc. (I am using the codebase as I need to modify the UI a little bit). Would appreciate help greatly :")

Hi channel, I keep getting this error while deploying explorer in kubernetes:
```{
code: 0,
message: "Registration of 'vulosadmin6' failed: Identity 'admin1' is already registered"
}
],```
The message is very descriptive and I understand that `admin1` is already registered
However this issue arrises because when I see the logs at `fabric-ca-server` the fabric-ca is being called multiple times to register `admin1`
At the 1st time its everything ok with a `200` but than `explorer` keeps calling it and that's why its failing
Does explorer support pkcs11?

Dear all,
Is anybody facing memory maxed out / CPU usage issue(198.74%) because of hyperledger explorer db ?
In my case, I am running the hyperledger explorer and hyperledger db as docker swarm services.
The output of docker stats command is below :
We can see hyperledger_explorer db service is consuming very high memory and CPU % . Because of this docker memory maxed out issue occurs and docker restarts. This affects other services in the swarm .
Can anybody help me to find out the reason behind this.
