COMPONENT NAME

KVM agent logs

CLOUDSTACK VERSION
4.20.0.0
CONFIGURATION

default /etc/logrotate.d/cloudstack-agent and /etc/cloudstack/agent/log4j-cloud.xml

OS / ENVIRONMENT

Ubuntu 22.04.5 LTS

SUMMARY

Regularly agent log is rotated but cloudstack agent keeps writing to old file.

STEPS TO REPRODUCE

just added kvm hosts to cloudstack cluster and used it to run several VMs
I believe at rotation time (0:17) there were several VMs running but no new tasks were executed

EXPECTED RESULTS

I'd expect that agent writes to the new agent.log after rotation

ACTUAL RESULTS

But it keeps writing to the old file

-rw-r--r-- 1 root root       0 Jan 13 00:17 agent.log
-rw-r--r-- 1 root root  319990 Jan 13 09:28 agent.log.1

Please advise.
Thanks.

    Looks like properly rotated files have different naming

        -rw-r--r-- 1 root root  274543 Jan 13 09:42 agent.log
    -rw-r--r-- 1 root root     358 Jan  8 11:57 agent.log.2025-01-07.gz
    -rw-r--r-- 1 root root   19103 Jan  9 00:00 agent.log.2025-01-08.gz
    -rw-r--r-- 1 root root   43687 Jan 10 00:00 agent.log.2025-01-09.gz
    -rw-r--r-- 1 root root   42734 Jan 11 00:00 agent.log.2025-01-10.gz
    -rw-r--r-- 1 root root   41832 Jan 12 00:00 agent.log.2025-01-11.gz
    -rw-r--r-- 1 root root   39186 Jan 13 00:00 agent.log.2025-01-12.gz

    must be some conflict with my logrotate configuration
