Postfix monitoring with Netdata

Monitors MTA email queue statistics using postqueue tool.

The collector executes postqueue -p to get Postfix queue statistics.

Requirements

Postfix has internal access controls that limit activities on the mail queue. By default, all users are allowed to view the queue. If your system is configured with stricter access controls, you need to grant the netdata user access to view the mail queue. In order to do it, add netdata to authorized_mailq_users in the /etc/postfix/main.cf file.

See the authorized_mailq_users setting in the Postfix documentation for more details.
