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.
To troubleshoot issues with the
postfix module, run the
python.d.plugin with the debug option enabled. The
output will give you the output of the data collection job or error messages on why the collector isn't working.
First, navigate to your plugins directory, usually they are located under
/usr/libexec/netdata/plugins.d/. If that's
not the case on your system, open
netdata.conf and look for the setting
plugins directory. Once you're in the
plugin's directory, switch to the
sudo su -s /bin/bash netdata
Now you can manually run the
postfix module in debug mode:
./python.d.plugin postfix debug trace
