There is a plugin at Nagios Exchange to monitor Exim's Mail Queue:

check_eximailqueue.

Put this script into your Nagios plugin directory. Adjust the paths to utils.sh and the exim binary if necessary.

On Debian you need to install nagios-plugins-basic first and use the following

paths:


. /usr/lib/nagios/plugins/utils.sh</code>

EXIM=/usr/sbin/exim4

Install <code>sudo</code> if necessary.

Now add the following line to <code>/etc/sudoers</code> with <code>visudo</code>:

<example>

nagios ALL=NOPASSWD:/usr/sbin/exim4

Add a line to nrpe_local.cfg on your mail server.


command[check_eximailqueue]=/usr/lib/nagios/plugins/check_eximailqueue -w 250 -c 500

Restart Nagios NRPE server with:


/etc/init.d/nagios-nrpe-server restart
