Some of the behaviours you observe may be due to the same bug I encountered:
https://dovecot.org/pipermail/dovecot/2019-July/116475.html
Especially, regarding the ‘successful' field for auth, which does not exists and is really named ‘success', and which is never set anyway.

Is there any additional documentation/information around the new stats module.
Have added some metrics just to see what they produce
## ## Metrics ###
metric imap { event_name = imap_command_finished #source_location = example.c:123
#categories = fields = name args running_usecs bytes_in bytes_out #filter { # field_key = wildcard #}}
metric sql { event_name = sql_query_finished }
metric auth { event_name = auth_request_finished fields = user transport error successful }
and get the following
[root@stargate dovecot]# doveadm stats dump metric_name field count sum min max avg median stddev %95 imap duration 370 2007904499 130 62955249 5426768.92 2068 16436817.37 60026465 imap name 370 0 0 0 0.00 0 0.00 0 imap args 0 0 0 0 0.00 0 0.00 0 imap running_usecs 370 2007865330 81 62955127 5426663.05 1991 16436816.76 60026329 imap bytes_in 370 5366 2 173 14.50 8 19.04 35 imap bytes_out 370 2119971 0 941517 5729.65 41 53760.89 2082 sql duration 18 28991 991 2305 1610.61 1660 377.36 2305 auth duration 12 26046980 8146 7079879 2170581.67 847730 2457811.23 7079879 auth user 12 0 0 0 0.00 0 0.00 0 auth transport 12 0 0 0 0.00 0 0.00 0 auth error 0 0 0 0 0.00 0 0.00 0 auth successful 0 0 0 0 0.00 0 0.00 0
the main wiki page on stats/events doesnt really hold much detail whats stores for each event the above fields dont make much sense
and top no longer works out of the box
[root@stargate dovecot]# doveadm stats top
usage: doveadm [-Dv] [-f <formatter>] stats <command> [<args>] dump [-s <stats socket path>] [-r] [-f <fields>]
has is been removed ? do you need to specify something additional now ???
