Ok, so MAAS install's an rsyslog config to forward messages from syslog to /var/log/maas/maas.log. Today we noticed that maas.log was completely empty, and on further checking, we noticed that syslog was completely empty as well. The fun fact, however, is that MAAS has not changed its syslog configuration in years, and we definitely don't believe this is the problem. Also, this was working before just fine without any issues before , and as such, we don't believe is a problem on rsyslog.
The interesting thing is that rsyslog hasn't really change much in the past few months (iother that 2, no change rebuilds). Also, syslog logs that should be on /var/log/syslog are on systemd's journal.
