The log rotation for Plone product installation would be a nice feature. What are the current best practices regarding the log rotation integration into Plone?
I found this article: http://encolpe.wordpress.com/2010/06/17/how-to-get-log-files-rotate-in-zope-with-buildout/ but as there are no documentation on plone.org I'd like to ping the community for the good known best practices not to fill up their hard disks.
Similar to what Laurence said above but keeps size under 10mb and saves only 1 old file.
<eventlog>
level INFO
<logfile>
path /path/to/plone4/var/log/client1.log
max-size 10mb
old-files 1
</logfile>
</eventlog>
plone.recipe.zope2instance can generate this now. For example, you can specify the following options:
event-log-max-size = 10mb
event-log-old-files = 3
