Description Eko 2019-01-07 07:27:48 UTC

We create a test case to test the max size of rhsm.log:

1. configure virt-who, make sure there are lots of guests in the hypervisor.

2. restart virt-who service frequently

3. check /var/log/rhsm/rhsm.log size


we found that virt-who will continue to add log message to rhsm.log file even the file's size is more than 1GB. 
# ls /var/log/rhsm/rhsm.log  -lha
-rw-r--r-- 1 root root 1.2G Jan  4 18:21 /var/log/rhsm/rhsm.log


Expected results:
There should be limitation for the rhsm.log file size.

Comment 1 William Poteat 2020-05-08 13:52:29 UTC

The log rotation is handled in subscription-manager and was fixed by https://bugzilla.redhat.com/show_bug.cgi?id=1803783

You will need to confirm this fix in RHEL 8.3, any 1.27 build will have it.

Verified with 
 virt-who-0.29.3-1.el8.noarch
 subscription-manager-1.27.13-1.el8.x86_64

# cat /etc/logrotate.d/subscription-manager 
/var/log/rhsm/*.log {
    missingok
    notifempty
    sharedscripts
    copytruncate
}

# systemctl restart virt-who

# logrotate -f /etc/logrotate.conf

# ll
total 12
