How are UM logfiles rotated?

While searching for some anomalies on my system [UM 16.04 install] I noticed that all but one logfile hasn't been backedup or rotated. This isn't a problem yet , but I prefer to be proactive rather than reactive wrt system maintenance.

Is there a process / script native to UM that can be configured? and if so how?

See /etc/logrotate.conf, mine is set to rotate log files weekly and keep 4 weeks.


Thanks! I found my setting is weekly.
Iā€™m pretty sure this is working correctly now ā€¦ the larger logs have first entry a week ago and I use bleachbit to remove rotated logs :blush:
