This document is part of the Operations Manager Management Pack Authoring Guide . 

Overview

The following procedure shows how to create a monitor based on a monitoring script using  the Operations Manager 2007 Authoring console and Visual Studio Authoring Extensions.

Product Versions

This exercise applies to the following products:

• System Center Operations Manager 2007 R2
• System Center 2012 Operations Manager
• System Center 2012 Operations Manager SP1

Prerequisites

Before you perform this procedure, you must first complete the following prerequisite procedures:

• Creating a New Management Pack - Create the management pack.
• Creating a Class - Create the class that is the target for the monitor.

Revisions

The Microsoft System Center team has validated this procedure as of Revision #1.  We will continue to review any changes and periodically provide validations on later revisions as they are made.  Please feel free to make any corrections or additions to this procedure that you think would assist other users

Sample Code

A sample of the completed code for each exercise is available in the TechNet Gallery.  There is a separate sample for each exercise that includes the management pack completed at the end of that exercise and each preceding exercise.  This strategy allows you to work through each exercise in order and then compare your results.  For VSAE, this also includes the Visual Studio solution. 

Details

The event monitor created in this procedure has the following characteristics:

• Runs on any computer that has an instance of MyComputerRole1.
• Sets the monitor to a critical state when the script returns a status message of Bad.
• Sets the monitor to a healthy state when the script returns a status message of Good.
• The script accepts only a single argument for the computer name of the target object’s agent.
•  The script itself is only for testing and performs no real function. It simulates a script running a synthetic transaction.
