Monitor your Eicon Diva Server with Nagios

Monitor your Eicon Diva Server with Nagios for HylaFAX.

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.
