atop (monitoring system) logs fill up instances /var/ partition
Closed, DeclinedPublic


I noticed 'atop' generates log files in /var/log/ which is on a 2GB partition. atop has a logrotate rule of 15 days / uncompressed.

On deployment-bastion.eqiad.wmflabs that is 334MB currently, or a sixth of /var/ available disk space.

I guess we want to compress the old archives.

This is too complicated. Newer labs instances should just have a unified / (coming sooooon)

The labs instance now have /var in the / partition that is 20GBytes. So that atop logs size is no more of an issue.
