/var/log/neutron/server.log should only contain logs from neutron-server

[Eugene Nikanorov]

Currently /var/log/server.log contains all logs from all neutron components: neutron-server, l3 agent, dhcp agent, etc.

That unnecessarily increases log file size and complicates log analysis.

/var/log/server.log should contain Neutron-server logs only.

[Eugene Nikanorov (enikanorov)]

Given the importance of log analysis for QAs and support team, I'd give this critical or high priority.
The fix should be fairly simple.

[Timur Nurlygayanov (tnurlygayanov)]

Priority is 'Critical' because we need this fix to have an ability to debug other bug with HA mode and L3 agent:

[Dmitry Mescheryakov (dmitrymex)]

IMHO the bug is not critical. If logging need to be changed for debug, that could be done manually

[Bogdan Dobrelya (bogdando)]

All neutron agents logs *are* separated from server, please look at /var/log/neutron/*.log
e.g.
root@node-1:~# ls /var/log/neutron/
dhcp-agent.log l3-agent.log neutron-ns-metadata-proxy-21c30e1e-e54c-4873-b72b-916bcb34b117.log rescheduling.log server.log.1.gz
fdb-cleaner.log metadata-agent.log openvswitch-agent.log server.log

[Eugene Nikanorov (enikanorov)]

The problem is in server.log file which contains logs from agents as well, while it only should contain logs from neutron-server

[Bogdan Dobrelya (bogdando)]

Please clarify how I can identify these log entries in server.log, are there any 100% sure matching templates?

[Eugene Nikanorov (enikanorov)]

You can identify them by looking at the prefix path of the component which is logging. You'll see lots of log lines containing messages from the agents. I'll attach a portion of such logs to illustrate the issue

[Bogdan Dobrelya (bogdando)]

Thank you for clarification, yes, please attach some - examples are really welcome.

[Bogdan Dobrelya (bogdando)]

@Eugene, please provide some examples. In order to investigate and fix, I really need to understand how could I be 100% sure either some given log line belongs to agent or to server.

[Eugene Nikanorov (enikanorov)]

Sorry for long delay.
Here is a copy-paste from server.log of one of the custom ISO (6.0):

http://paste.openstack.org/show/121160/

Pretty much everything matching prefix 'neutron.agent' in a log line is logged by agents, not neutron-server.

[Bogdan Dobrelya (bogdando)]

Neutron agents should be run with explicitly set --log-file destination
