Logrotate is rotating the file, but not signaling your Python script when this happens. So yes, as you have noticed, the rotation will not work correctly with this setup.
You have two options. First and preferred option I think: forget about logrotate and make your Python script rotate the logs by itself. I see the Python logging library already has support for this: https://docs.python.org/3/library/logging.handlers.html#rotatingfilehandler This simplifies things since you no longer have to synchronize two processes (logrotate and your script). The second option would be to use logrotate and: - configure the postrotate script to send a HUP signal to rsyslog - in rsyslog, configure the 'hup.signal' flag of omprog to forward the HUP signal to your script - in your Python script, handle the HUP signal by reopening the log file Regards Joan On Tue, May 26, 2020, 05:58 Fourhundred Thecat via rsyslog < [email protected]> wrote: > Hello, > > in my /etc/rsyslog.conf, I am calling external script to handle > mail.* logging: > > mail.* action(type="omprog" name="blacklist-postfix" > binary="/usr/local/sbin/postfix.py" template="long-iso") > > This custom script processes logs, and writes to /var/log/mail/mail.log > > Everything works well, except my logs are not being logrotated properly. > This is my logrotate config: > > /var/log/mail/mail.log { > rotate 4 > weekly > sharedscripts > postrotate > invoke-rc.d rsyslog rotate > /dev/null > endscript > } > > I suspect, the problem is that "invoke-rc.d rsyslog rotate" does rotate > rsyslog, but not my external script. > > What would be the proper way to handle this? > Do I have to restart rsyslog, so that my script is terminated and > started anew? > _______________________________________________ > rsyslog mailing list > https://lists.adiscon.net/mailman/listinfo/rsyslog > http://www.rsyslog.com/professional-services/ > What's up with rsyslog?
