Getting login stats

[Jean-Daniel Dupas]

Hello,

I'm trying to get some IMAP auth stats on a Dovecot 2.3.6 instance, but whatever I declare in metric, it always show 0.

What I want basically is how many IMAP auth attempts there was on the server, and optional a way to filter on the auth attempt status (successful or failed).

My server uses a simple auth (with LDAP backend) and supports only "auth_mechanisms = plain login"



I tried using the following metrics:


--------------------------------
metric auth_request_finished {
    event_name = auth_request_finished
}

metric auth_passdb_request_finished {
    event_name = auth_passdb_request_finished
}

metric auth_userdb_request_finished {
    event_name = auth_userdb_request_finished
}

metric auth_client_request_started {
 event_name = auth_client_request_started
}

metric auth_client_userdb_lookup_started {
    event_name = auth_client_userdb_lookup_started
}

metric auth_client_passdb_lookup_started {
 event_name = auth_client_passdb_lookup_started
}

metric auth_client_cache_flush_started {
 event_name = auth_client_cache_flush_started
}

metric imap_command_finished {
    event_name = imap_command_finished
    filter {
                name = LOGIN
    }
}
--------------------------------

But even after many successful logins, doveadm reports 0 for all events:
