Using SCOM 2012 SDK to Retrieve Resource Pools Information

Today I needed to retrieve information about SCOM 2012 resource pools in a PowerShell script, I needed to do this directly via SDK, rather than using the OperationsManager PowerShell module. I couldn’t find any existing scripts via Google, so I spent some time playing with SDK and finally found it. Since it seems no one has mentioned it on the web, here’s how I did it:

Firstly, load the SDK DLL’s. I always use below function:

function Load-SDK()
{
  [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.EnterpriseManagement.OperationsManager.Common") | Out-Null
  [System.Reflection.Assembly]::LoadWithPartialName("Microsoft.EnterpriseManagement.OperationsManager") | Out-Null
}

Load-SDK

Secondly, connect to the management group. Since I’ll be running this script on a management server, I’m connecting to the management group via the SDK service on the local machine:

$MGConnSetting = New-Object Microsoft.EnterpriseManagement.ManagementGroupConnectionSettings($env:computername)
$MG = New-Object Microsoft.EnterpriseManagement.ManagementGroup($MGConnSetting)

Then, get the management group administration

$Admin = $MG.Administration

Finally, get all resource pools

$ResourcePools = $admin.GetManagementServicePools()

In the past, I’ve been using the GetAdministration() method from the management group object to retrieve MG administration object. This time, When I did it, the MG administration object returned from the method does not contain a method for GetManagementServicePools. I then realised the management group contains a property called Administration. the object type is the same as what’s returned from GetAdministration() method.

But it looks like the object returned from the “Administration” property contains more members:

This is just a quick observation. In the future, I’ll remember to check both places.
