How to monitor an Exim queue on a WHM server using SNMP and PRTG

This technique uses an HTTPS connection and PRTG’s integer type to keep track of the queue size.

You have to pick a “static” site on your server, ie. one that will never be deleted.

The contents of exim.sh is:

#!/bin/bash
echo "[`/usr/sbin/exim -bpc`]" > "/home/domain/public_html/exim/eximqueue.txt"

The CRON required is this:

* * * * * /bin/sh /home/domain/public_html/exim/exim.sh

Now every minute it will count the message and output a text file. For example:

cat eximqueue.txt
[10]

Now in PRTG you can use the HTTP content sensor that looks like this:

When adding the PRTG sensor, specify the path to the website TXT file, e.g. https://domain.com/exim/eximqueue.txt
