dovecot - Jul 2017 - Dovecot Statistics

I tried to setup statistics as shown on the Statistics wiki page.  I encountered
a problem with the mail_plugins for imap.  in the protocol imap configuration
the wiki shows adding imap_stats to mail_plugins.  When I do that, dovecot stops
authenticating and throwing error messages:

 Jul 15 12:47:46 mail dovecot: imap(doug)[10.0.1.251]<osGhcGBUmsgKAAH7>:
Error: Couldn't load required plugin
/usr/local/lib/dovecot/lib95_imap_stats_plugin.so: Plugin stats must be loaded
also (you must set: mail_plugins=$mail_plugins stats)
Jul 15 12:47:46 mail dovecot: imap(doug): Error: Internal error occurred. Refer
to server log for more information.


Changing that line to just add stats to mail_plugins resolves the problem. 
Hopefully that is an error in the wiki...  However, in looking at the stats, I
don't ever see any values for any of the auth_ values.  They all show zero
even though there have been numerous authentications by dovecot and postfix.

I also notice that there is a new statistics output about every 3 minutes.  It
appears that the numbers are only for that 3 minute window.  Is there a way to
set the statistics so that I can see the last 24 hours, or the previous day?

Doug, according to the wiki it should be:

mail_plugins = $mail_plugins stats
protocol imap {
   mail_plugins = $mail_plugins imap_stats
}

It sounds as if you were missing the first line in global config scope.

For auth stats add to your config:
auth_stats = yes
