[Dovecot] Dovecot Top?
Hello,
We occasional see high load peaks on our mail servers - these generally don't only last a few minutes. 'Top' show imap taking the lots of CPU resources, is there a dovecot 'top' like program to show dovecot which users are taking system resources?
Or how else can this kind of thing be tracked down?
(v1.1.7)
Thanks.
Andrew.

That is something I've wished to implement for a long time, but I
never really have time. But v1.2 keeps track of various things and it
would be possible to create some kind of a dovecot-top based on those.
Currently there's a stats plugin that can log some of those things: http://dovecot.org/patches/1.2/stats-plugin.c
Although that plugin doesn't currently log what I added most recently: http://www.mail-archive.com/dovecot@dovecot.org/msg18477.html
