How to create a monitor based on a script

Applies To: System Center Operations Manager 2007

The following procedure shows how to create a monitor based on a monitoring script in the Operations Manager 2007 Authoring console. Before you perform this procedure, you must first complete the prerequisite procedure How to Create a Class in which you create the target class.

The monitor created in this procedure has the following characteristics:

• Runs on any computer with 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.
