Hi,
I've not found the answer to this question anywhere - please forgive me if I overlooked.
I'd like to be able to be automatically alerted if process limits are hit (e.g. max POP3 logins).
Is there a way that I can configure a script to be run, in the same way that I can with quota warnings?
I can of course use logwatch, but this alerts me the next day, and logwatch can be noisy and it's easy to overlook.
My motivation: for some reason my POP3 listener was hanging, and I had to restart dovecot (this is 2.0.9). But I was not aware - the process was still there, it was accepting connections (but not doing anything useful with them) and was actually managing to log the fact that the process limit was being hit (as more and more connections came in). If I could have been alerted I could have restarted dovecot earlier.
Many thanks, David
I believe that nagios or icinga could do this for you with a log analyser plugin.
