SCOM: Get Nested Group Members (Powershell)

When you create nested groups in SCOM you have to use workarounds to view the actual group members of a specific type, e.g. Windows Computer. Using 'View Members' only returns the nested groups and not the contained objects.

One of the ways to view the actual members of a group, is to create a 'State View'.
As a "filter" you then change the class type to show the data related to the type you want to see and then you select the group for scoping the returned data.

So in short terms, to view the nested group members
- Create a state view
- Change "Show data related to" to a class like 'Windows Computer'
- Change "Show data contained in a specific group" to the group of which you want the members.

But, there's quicker way to achieve this. Using Powershell you can retrieve the members of a nested group in a couple of seconds. I found out about 'Recursive' using the SCOM SDK.

$group = Get-MonitoringObject | Where { $_.DisplayName -eq "YourGroupName"}
$MonitoringClass = Get-MonitoringClass -Name "Microsoft.Windows.Computer"
$group.GetRelatedMonitoringObjects($MonitoringClass,"Recursive") | Select DisplayName
