Stats/Metrics in 2.3

Greetings,

So the changes to the stats modules between v2.2 and v2.3 have broken some
of my monitoring. I am attempting to use the new method of gathering
"metrics" from "events" - but the details in the documentation are a bit
thin.

I started with the examples provided at 
https://wiki2.dovecot.org/Statistics and tried to build from there with
only moderate success. What I am trying to achieve is the monitoring of
login attempts (with successes and failures as separate modules - as well
as aborted attempts), user sessions an bytes transferred. All this for
multiple virtual domains and users.

I have attached my current /etc/dovecot/conf.d/10-stats.conf so people can
see what I have attempted so far. Based on that file the output I get is:

   # doveadm stats dump

Based on the metrics I have set I would expect to see entries in the first
2 lines at least, given that there are multiple users logged into the
server from the monitored domain (or at least the domain I am trying to
monitor to begin with).

I am also not sure how to get the session and data transfer information out
of the metrics/stats system.

If anyone can help me I would appreciate it.

Thanks
