Where does logrotate save its own log?

Solution 1:

logrotate does not log anything by default. normally it should be in your cron somewhere, for instance:

$ grep -r -- 'logrotate.conf' /etc/cron*
/etc/cron.daily/logrotate:/usr/sbin/logrotate /etc/logrotate.conf

You can either run that manually to see what is wrong, or redirect the logrotate output to a file in the above cron to see what happened next day.

Likely somewhere the config is incorrect and caused the logrotate run to break.

Solution 2:

The only thing that logrotate records normally is in cat /var/lib/logrotate/status.

Solution 3:

Another good place to look is /var/log/messages on CentOS for errors such as this from the cron.daily /etc/cron.daily/logrotate

logrotate: ALERT exited abnormally with [1]

You can also run in debug mode manually and check for errors:

/usr/sbin/logrotate -d /etc/logrotate.conf

Solution 4:

If you're running logrotate from cron and not redirecting the output, the output, if there is any, will go to email for whichever ID is running the cron job. I redirect my output to a log file.

For example:

25 3 * * 7 /usr/sbin/logrotate -s /home/user/conf/mwarelogrotate.state 
/home/user/conf/mwarelogrotate.conf >> /home/user/logs/logrotate.log 2>&1
