Monitor your Eicon Diva Server with Nagios

If you have an advanced ISDN card like an Eicon Diva Server PRI card, you will probably be aware it has a web interface that can, amongst many other things, indicate the status of the card and the line. Here is a Nagios plugin script that will read this data and feed it back into Nagios. You will need wget installed.
