Peer Node Log File Location

Q

Where are Peer Node Log Files located?

✍: FYIcenter.com

A

Log files of the Hyperledger Composer peer node in the Docker container that runs the peer node. You can use these commands find peer node log files:

1. Find the container id of the peer node:

$ docker ps | grep peer

6bc4e52f82d0        hyperledger/fabric-peer:x86_64-1.1.0   ... 

2. Fetch most recent log messages from the container:

$ docker logs 6bc4e52f82d0

...

   logger enabled for log level 'ERROR'

   new Deliver handler

2019-04-01 14:08:53.708 UTC [common/deliver] Handle -> WARN 1ea Error reading 
   from 127.0.0.1.1:38768: rpc error: code = Canceled desc = context canceled
2019-04-01 14:08:53.708 UTC [common/deliverevents] func1 -> DEBU 1eb Closing 
   Deliver stream

3. If you want to get log messages after a specific date and time, you can use the "--since" option and redirect them to a file:

$ docker logs --since 2019-04-01 6bc4e52f82d0 2> peer.log

4. You can also follow and watch the log file in real time using the "-f" option. This is a good idea to troubleshoot any Hyperledger Composer runtime issues. Press "Ctrl-C" to stop it.

$ docker logs -f 6bc4e52f82d0
