Limit log files rotation
Hi,
I'd like to limit log rotation to a specific number of days to avoid that
the logs folder keep growing indeterminately.
Tried to google about, people say to study Log4j or use crontab,
but isn't there an easier way like a *maxHistory* property?
Thanks,
Phillip

Watch out when using "logrotate" with the "copytruncate" option, in some circumstances this can result in data loss.

Tomcat offers several ways to handle logging out-of-the-box, including the one you mentioned. I believe it's documented here.

This is entirely the point of using logrotate: it does one job, and it
does it well. It fits-in very well with the UNIX philosophy. Embrace it.
Apache httpd also doesn't rotate its own log files, though it can be
taught to do it, either using their own logger service or... using
logrotate. Note that neither of these solutions is really httpd doing
the work: it's some external tool, though httpd does make it somewhat
easier. (Copytruncate always seemed like such a hack to me, but it
definitely makes the daemon process simpler to write and manage).

Thanks for the link.
Searching a bit more I found this:

Simple to setup, but anyway it would be nice if Tomcat could do this out of
the box, since the server can crash if it runs out of disk space.

Which log files are you referring to? Including the names would help.

Tomcat's default logging mechanism will simply rotate files. It does not perform any cleanup or archival.
If you want those features, you have two choices …
1.) Setup a cron job to cleanup or archive old log files.
2.) Use Tomcat's log4j support. Log4j supports cleanup and archival.

There's probably other things you can do as well. Those are just the first two that popped into my head.
