Start the Operations Manager 2007 Create Rule Wizard.

Note
For information about starting the Create Rule Wizard, see How to Start the Create Rule Wizard in Operations Manager 2007.

On the Select a Rule Type page, do the following:

1. Expand Collection Rules, expand Performance Based, and then click Windows Performance.
   
   
2. Select a Management pack from the list or click New to create a management pack with the Create a Management Pack Wizard.
   
   

   Note

   The rule will be added to the specified management pack, therefore only unsealed management packs are listed. 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.

3. Click Next.
   
   

On the Rule Name and Description page, do the following:

1. Type the Rule name, such as % Processor.
   
   
2. Click Select, click a target, such as Windows Computer, and then click OK.
   
   
3. Leave Rule is enabled selected, and then click Next.
   
   

On the Performance Object, Counter and Instance page, do the following:

1. Click Browse.
   
   
2. In the Select Performance Counter dialog box, type a computer name or browse to the Computer that is running the performance counter.
   
   
3. Select the Object you want to collect performance counter data for, such as Processor.
   
   
4. In Select counter from list, select the counter for the object, such as % Processor Time, select All Instances, and then click OK.
   
   
5. Set Interval to how often you want the performance counter collected on the targeted computers, and then click Next.
   
   

On the Optimized Performance Collection Settings page, do one of the following:

• Click Create.
  
  
• Select Use Optimization, select Absolute Number or Percentage, type the value for the tolerance, and then click Create.
  
  

  Note
  With optimized collection rules, only if a sample of a counter differs from the previous sample by a specified tolerance, such as 10%, is it transmitted from the agent to the management server. This helps reduce network traffic and the volume of data stored in the Operations Manager 2007 database.
