Timo,
following our discussion on dovecot stats at the LinuxTag 2012 my team and I sat down and put together a list of stat items we think to be useful in daily dovecot usage.
Besides pulling together all the data we also think it would be useful to have an SNMP interface to access the stats. Our offer to create and contribute a standalone web interface for dovecot stats stands.
Here are the stats we believe to be useful:
Login/Logout
- total number login success/time
- total number login failure/time
- total number per authentication mechanism
- total number plain sessions
- total number STARTTLS sessions
- total number of currently connected users (pop3/pop3s/imap/imaps/managesieve)
- login names of connected users (not really stats, but great for actions regarding those uses e.g. force logout)
- total number logout commands/time
- total number BYE responses (autologout)
Mailbox state
- Inflow rate (number incoming messages/time)
- Deleted rate (number \Deleted flagged messages/time)
- Expunge rate (number Expunge operations/time)
- total number current messages mailboxes normal storage
- total number current messages mailboxes alt storage
- total number read messages mailboxes normal storage
- total number read messages mailboxes alt storage
- per user number current messages mailboxes normal storage
- per user number current messages mailboxes alt storage
- per user number read messages mailboxes normal storage
- per user number read messages mailboxes alt storage
Mailbox Quota
- total number persons under soft-quota per quota
- total number persons above or equal soft-quota per quota
- total number persons above or equal hard-quota per quota
Performance
- minimum time to write a message
- maximum time to write a message
- average time to write a message
- minimum time to modify a message
- maximum time to modify a message
- average time to modify a message
- minimum time to delete a message
- maximum time to delete a message
- average time to delete a message
- minimum time search operations
- maximum time search operations
- average time search operations
