I had thought about SNMP before also, but for the current kind of stats that are exported I couldn't think of any reasonable way to export them. > Here are the stats we believe to be useful: > > Login/Logout > - total number login success/time > - total number login failure/time .. I'll look at these later in more detail, but some important questions / design decisions: Currently stats process only remembers things after Dovecot was started. I don't think getting these kind of numbers would really work like that. Perhaps all of the statistics should be permanently dumped to disk every ~minute or so + at shutdown and loaded at startup, so the numbers would at least normally always just increase since the first time Dovecot was started? > Mailbox state > - Inflow rate (number incoming messages/time) > - Deleted rate (number \Deleted flagged messages/time) These operations/time type of things I had hoped to be able to externalize :) If stats process simply gives the raw stats, the reader could do this kind of summing up. Otherwise .. well, I guess it could maybe keep track of the current ops/<last 60 secs> and the reader would then have to read the value about once a minute or half or something. It wouldn't give exact results though. > Performance > - minimum time to write a message > - maximum time to write a message > - average time to write a message Within last .. day? hour? minute? ..
