How do I create a dynamic group of computers of specific OS and agent version?

Question

Hi,

We are in the middle of SCOM 2019 upgrade project and using following Kevin's MP for multi-home.

https://kevinholman.com/2018/06/12/how-to-multihome-a-large-number-of-agents-in-scom/

But we have got a bit tricky situation. We want to multihome only those computers that are Windows Server 2012, 2016 and 2019, and agent version is equal or greater than 10. Now on paper, it doesn't look a challenge, create a dynamic group and override that Kevin's specific rule.

But I don't know why I can't create a dynamic group with above mentioned criteria. Can anyone please share a formula or line of code that I can use in XML if it's not possible via console? I will be highly obliged.

Hi,

Sorry for missing this thread. I'm afraid that this cannot be done with the existing one. My thoughts is to deploy a script to all the managed Windows agents (via group policy or other management tool, such as configuraion manager) to add the new management group (multi-homed).

Here's the script for your reference (just illustrate how it works and you may need to modify it to cater for the real environment)

	$mma1 = New-Object -ComObject 'AgentConfigManager.MgmtSvcCfg'  
	  
	#$computers = import-csv c:\temp\computer_list.csv  
	  
	#check if the new management group already exists  
	$p = $mma1.GetManagementGroup("test01")  
  
  
	#if it does not exist, then check the criteria and add the new management group if the condition is met.   
	if ($p -eq $null)  
	{  
		$agent_version = (Get-ItemProperty "HKLM:\SOFTWARE\Microsoft\Microsoft Operations Manager\3.0\setup" -ea silentlycontinue).AgentVersion  
		  
		#for debugging  
		$agent_version  
		[environment]::OSVersion.Version.major  
		[environment]::OSVersion.Version.major -ge 6 -and $agent_version -like '10.*'  
		  
		if ([environment]::OSVersion.Version.major -ge 6 -and $agent_version -like '10.*')  
		# server 2012/2012r2: 6  
		# server 2016/2019: 10  
		{  
			$mma1.AddManagementGroup('test01' , 'om16.sc.com' , 5723)  
			write-host "management group test01 was added!"  
			$mma1.ReloadConfiguration()  
		}  
	}  
	else  
	{  
		"test01 already exists!"  
	}
