Monitors MTA email queue statistics using postqueue tool.
The collector executes
postqueue -p to get Postfix queue statistics.
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
authorized_mailq_users in the
authorized_mailq_users setting in
the Postfix documentation for more details.
It produces only two charts:
Postfix Queue Emails
Postfix Queue Emails Size in KB
Configuration is not needed.
