Dovecot metrics: text format parsing error in line 5: unknown metric type "info"

[djdejawu]

I've got Dovecot: 2.3.17 (e2aa53df5b)

dovecot.conf

service stats {
    inet_listener http {
        address = *
        port = 9900
    }

}

metric auth_success {
    filter = event=auth_request_finished AND success=yes
}

metric auth_failures {
    filter = event=auth_request_finished AND NOT success=yes
}

metric imap_command {
    filter = event=imap_command_finished
    group_by = cmd_name tagged_reply_state
}

metric smtp_command {
    filter = event=smtp_server_command_finished
    group_by = cmd_name status_code duration:exponential:1:5:10
}

metric mail_delivery {
    filter = event=mail_delivery_finished
    group_by = duration:exponential:1:5:10
}

when I try to push metrics from dovecot to pushgateway got this error
text format parsing error in line 5: unknown metric type "info"

That's because Dovecot seems to emit OpenMetrics, not the conventional Prometheus text format, while the Pushgateway only understands the latter. Supporting OpenMetrics is tracked in #400 .
