I have a cluster of Mitel 3300 ICP PABX’s across several offices internationally and have been looking for a monitoring solution that can send alerts whenever an alarm is triggered on any one of the PABX controllers. Mitel already have a monitoring solution called Enterprise Manager, but this didn’t do what I wanted it to do. Enterprise Manager will send out emails based on certain policies and allow for issue escalation but its features are a little limited. I already have an extensive Nagios setup that will SMS and email for alerts, so I looked at integrating with this system.
I had a failure in one of my Exchange Storage Groups last night and the Storage Group had dismounted itself. However the Information Store service was still running and so were the other three Storage Groups on the server. So that got me to thinking, how do I monitor the individual Storage Groups for failures with Nagios?
