Create a Group of Windows Computers that CONTAIN an object that is CONTAINED by another group

image

 

Recently had a customer ask this question:

I have a group of IIS Websites that match some property.

Can I create a NEW group of Windows Computers, that CONTAIN those same websites that are CONTAINED by the other existing group?

The answer is absolutely.

There are two ways to tackle this.  You can create a new group of Windows Computers that contain an IIS Website with the same expression property in the new group with no relationship to the existing group of websites….. OR you can reference the existing group.

This example is the latter – referencing the containment relationship of the Website group.

Here is the simple membership rule:

  <MembershipRules>
    <MembershipRule>
      <MonitoringClass>$MPElement[Name="Windows!Microsoft.Windows.Computer"]$</MonitoringClass>
      <RelationshipClass>$MPElement[Name="MSIL!Microsoft.SystemCenter.InstanceGroupContainsEntities"]$</RelationshipClass>
      <Expression>
        <Contains>
          <MonitoringClass>$MPElement[Name="MWIIS2016!Microsoft.Windows.InternetInformationServices.10.0.WebSite"]$</MonitoringClass>
            <Expression>
              <Contained>
                <MonitoringClass>$MPElement[Name="Demo.Group.DefaultWebsites.Group"]$</MonitoringClass>
              </Contained>
            </Expression>
        </Contains>
      </Expression>
    </MembershipRule>
  </MembershipRules>
