One of the critical components of OEM is the ability to send notifications when a metric hits a certain threshold. If you are running the OEM Management Server (MS) Components on a UNIX/Linux based system then it's a trivial task to send out email notifications because MS will use the built-in mail server to send the email notification. We are going to focus on the non-trivial tasks of actually calling the staff member thats on duty and telling him that one of the servers hit a critical metric.
Setting this up will consists of a number of blog entries. But, here's my outline:
1) Create a test OS Script that will output values that gets executed when an alert happens
3) Configure the VoIP Server to receive request from OEM via a RESTFUL API.
4) Perform Some testing
5) Provide you with the code and the Asterisk Virtual Box Image that I used to create this.
Let the fun began!
