dovecot - Feb 2021 - Monitoring Dovecot Replication

Hello,

I have a cluster with two dovecot nodes with dovecot replication between them. 
The setup works fine and now I'm searching for a way to monitor the users so
that I can get an information if the replication fails for one user for a longer
time and I have to trigger the replication manually. Most of the time if I see a
replication failure the self healing of dovecot replication repairs this in max.
10 min.

I have tried different combinations of querying " doveadm replicator status
'*' " and search for failed users and then send an alarm if one of
fast sync, full sync or success sync reaches a threshold. But there is no
combination that seems to be working if I only want to trigger this if I have to
fix the replication manualy.

Can someone tell me what I have to query to get only the user who's
replication failed for a longer time (10 min +) and that I have to fix manually?

Thank you.

Oliver

Hello,

I wrote a little script for Check_MK (MRPE mode).

If you want to try it I can send it to you.
