Hi @Brian W ,

I have never heard of an MP with this particular functionality, but I certainly know how I would do this. I won't go looking for the agent version on each agent locally, but rather get all agents versions directly from SCOM. I would do this using PowerShell and the create a PowerShell based Monitor, which will alert on "unwanted" agent version.
This is pretty easy to achieve, you need:

• the PowerShell Authoring MP from Cookdown/SquaredUp
• the script
• Integrate the script in SCOM, example in the article I wrote here:

Monitoring Active Directory User Account Expiration using SCOM and PowerShell (Step by Step Guide)
https://www.pohn.ch/monitor-active-directory-user-account-expiration-using-scom-and-powershell-step-by-step-guide/

The script for this should be easy to create, something like this:

#Compare alll agents to the SCOM 2019 UR4 Version  
$VersionToCompare = "10.19.10200.0"  
  
  
#Clear Errors  
$Error.Clear()  
  
#Prepare API and Property Bag Objects  
$ScomAPI = New-Object -ComObject "MOM.ScriptAPI"  
$PropertyBag = $ScomAPI.CreatePropertyBag()  
  
  
    try {  
         
        $AllAgents = Get-SCOMAgent  
  
        foreach ($Agent in $AllAgents)  
        {  
          
        #get the agent version  
        $AgentVersion = (Get-SCOMAgent -Name $Agent.Name).Version  
  
        if ($AgentVersion -eq $VersionToCompare) {  
  
        $PropertyBag.AddValue("State","Healthy")  
        $PropertyBag.AddValue("Version",$AgentVersion)  
  
        } else {  
          
        $PropertyBag.AddValue("State","Warning")  
        $PropertyBag.AddValue("Version",$AgentVersion)  
          
        }  
  
     }   
      
    } finally {  
      #Send the whole output to SCOM  
      $PropertyBag  
    }  

Then you just create the monitor and you have it. Of course the Powershell script can be extended easily to accomodate even more complex logic, but I think thiss is a nice start.

I hope I could help you out with that!
