This is a simple plugin that is based on one by Jason Rivers We have changed it now to read the ASTDB (Asterisk internal Database and then based on ok and Critical keys it will report OK or Critical staus reports to Nagios.
This was written for reporting if an Elastix system is in Day or Night mode.
You can define the Database Family, Key, Critical value and OK value. This means you can cutomise it to what ever you need to report.
The Code is below, make you may need to change /usr/bin/nc for what ever you use for netcat.
any issues email us, but dont forget this is given for free not supported for free.
