uses old dovecot stats module

[jelmer]

This exporter relies on the old style dovecot stats module (https://wiki2.dovecot.org/Statistics/Old), which has been replaced with a new (built-in) system as of version 2.3 (https://wiki2.dovecot.org/Statistics)

Thanks for your issue.
Feel free to send a pull request, unfortunately we are currently not working on this.

I never got it working either way, with the old or new stats modules. Always received a message roughly like this:

dovecot_exporter[13321]: 2018/10/16 16:37:37 Failed to scrape socket: Input does not provide any columns```

@ageis does sudo doveadm stats dump user give the right output?

[dpunkturban]

I'm receiving the same output as @ageis

Is there any fix for that?

2.2.36 (1f10bfa63)```

Thanks

Same error than @ageis for dovecot 2.3.4

see https://doc.dovecot.org/configuration_manual/stats/old_statistics/#old-statistics to configure the old stats and https://wiki2.dovecot.org/Upgrading/2.3 vor the changes to the setings names.

for me it works on dovecot 2.3.9

How did you got it to work ?
I've been trying to get it to work but it just wont export the statistics.

FWIW, it looks like dovecot gets native support for prometheus-style metrics soon: dovecot/core@d22a324

I've been trying to get it to work but it just wont export the statistics.

in conf.d/10-old-stats.conf

service old-stats {
    fifo_listener old-stats-mail {
        user = vmail
        mode = 0600
    }
}

plugin {
    old_stats_refresh = 30 secs
    old_stats_track_cmds = yes
}

i think that was all, as it was some time ago i don't know if there was more

For anyone else coming across this, it is officially supported in dovecot from version 2.3.11 https://doc.dovecot.org/configuration_manual/stats/openmetrics/

Can't install it on focal, but I got it working on hirsute. It's very simple to configure now.
