Services

Ganglia

Installation details can be found here.

Starting up gmetad can sometimes fail with this log entry:

May 11 10:49:56 t3ce01 /usr/sbin/gmetad[5651]: Please make sure that /var/lib/ganglia/rrds is owned by nobody

I am not yet sure what causes /var/lib/ganglia/rrds to be owned by root after reboots.

Backups

OS snapshots are nightly taken by PSI VMWare Team ( like Peter Huesser ) + we have LinuxBackupsByLegato to recover a single file.
