Log on to the computer with an account that is a member of the Operations Manager Administrators user role or Operations Manager Authors user role for the Operations Manager 2007 management group.

In the Operations console, click the Authoring button.

In the Authoring pane, expand Authoring, expand Management Pack Objects, and then click Monitors.

Click the Scope button.

In the Scope MP Objects by target(s) dialog box, in the Find text box, type Windows Computer, select the Windows Computer target check box, and then click OK.

In the Monitors pane, expand Windows Computer, expand Entity Health, right-click Performance, point to Create a monitor, and then click Aggregate Rollup Monitor.

In the Create a new aggregate rollup monitor Wizard, on the General Properties page, in the Name box, type a name for the aggregate rollup monitor, and then you can optionally type a description.

Note

You can either select a management pack from the Select destination management pack list or create a new unsealed management pack by clicking New. By default, when you create a management pack object, disable a rule or monitor, or create an override, Operations Manager saves the setting to the Default Management Pack. As a best practice, you should create a separate management pack for each sealed management pack you want to customize, rather than saving your customized settings to the Default Management Pack. For more information, see Default Management Pack.

In the Parent monitor list, click the appropriate parent monitor, and then click Next.

On the Health Rollup Policy page, do one of the following:

• Click Worst state of any member if you want the health state of the aggregate rollup monitor to reflect the least healthy state of any of the child monitors, and then click Next.
  
  
• Click Best state of any member if you want the health state of the aggregate rollup monitor to reflect the most healthy state of any of the child monitors, and then click Next.
  
  

On the Configure Alerts page, specify the alert settings appropriate for your environment, and then click Create.

Create child monitors of which this aggregate will become the parent. For more information, see How to Create a Self-Tuning Threshold Monitor in Operations Manager 2007 or How to Create a Static Threshold Monitor in Operations Manager 2007.
