Revisions

The Microsoft System Center team has validated this procedure as of the original version.  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 relationships created in the following procedures have these characteristics.

  • Relationship between MyHealthRollup group class and MyComputerRole1 class. This supports a health rollup of all instances of MyComputerRole1.
  • Relationship between MyComputerRole2 and MyComputerRole1. This supports a health dependency of MyComputerRole2 on MyComputerRole1.

Containment relationships do not have to be created for Instance Groups or Computer Groups, because the required relationships are already defined by the classes on which these classes are based.

Visual Studio Authoring Extensions Procedure

Creating a containment relationship for a health rollup

  1. Right click the name of the solution and select Add and then New Item. 

  2. Select Relationship.

  3. In the Name box, type Relationships.mpx and click Add.

  4. Remove the comments from the Relationships.mpx file.

  5. Replace the RelationshipType entry with the following XML. This creates the relationship between the Health Rollup and Computer Role 1 classes.

    <RelationshipType
  ID="MyMP.MyHealthRollupContainsMyComputerRole1"
  Base="System!System.Containment"
  Abstract="false"
  Accessibility="Internal">
  <Source ID="Source" Type="MyMP.MyHealthRollup"/>
  <Target ID="Target" Type="MyMP.MyComputerRole1"/>
</RelationshipType>

  6. Replace the DisplayString entry with the following XML. This creates the display string for the Computer Role base abstract class.

    <DisplayString ElementID="MyMP.MyHealthRollupContainsMyComputerRole1">
  <Name>My Health Rollup Contains My Computer Role 1</Name>
  <Description></Description>
</DisplayString>

  7. Select File, and then click Save Relationships.mpx.

  8. Select Build and then Build Solution.

  9. Ensure that you don't receive any errors.

Creating containment relationship for dependency between two classes

  1. In Relationships.mpx, add the following XML after the RelationshipType definition for MyMP.MyHealthRollupContainsMyComputerRole1. This creates the relationship between the Computer Role classes.

    <RelationshipType
  ID="MyMP.MyComputerRole2ContainsMyComputerRole1"
  Base="System!System.Containment"
  Abstract="false"
  Accessibility="Internal">
  <Source ID="Source" Type="MyMP.MyComputerRole2"/>
  <Target ID="Target" Type="MyMP.MyComputerRole1"/>
</RelationshipType>

  2. Replace the DisplayString entry with the following XML. This creates the display string for the Computer Role base abstract class.

    <DisplayString ElementID="MyMP.MyComputerRole2ContainsMyComputerRole1">
  <Name>My Computer Role 2 Contains My Computer Role 1</Name>
  <Description></Description>
</DisplayString>
