For a couple of months I didn't receive all the wanted log files by email upon the weekly log rotation and finally found the cause: two configs inside /etc/logrotate.d were broken, invalid. This on my Ubuntu 15.04 server.
That caused the logrotate service to crash in the middle.
I found that out myself by doing manual log rotations with
$ sudo logrotate -v -f /etc/logrotate.conf
I wish I were notified by email about that. Or to see some log entries about the failed logrotation in /var/log but no, nothing happened.
Do you have an idea how I can configure email alerts when logrotations failed themselves?? Or have these at least logged into something like /var/log/logrotation.log and /var/log/logrotation.err?
Thanks heaps
