Hello,

after updating my monitoring PC to Windows 10 I have a funny problem.

It seems the standard Powershell modules are no longer reachable from PRTG.

I have to import for example Microsoft.PowerShell.Management to get Get-WMIObject working.

Kind regards Ingo

Thanks for the hint! With which sensor did you try it? PowerShell v5 seems to have it's caveats as it seems :(

It's the EXE/Script Advanced-Sensor.

The sensor and the same script worked without problem under Windows 8.1

Are all PowerShell cmdlets affected that you use in the custom scripts? Just so we know if it's a general problem or just certain cmdlets.

At the moment I'm only using three cmdlets in my scripts which were not running:

  • Get-WmiObject
  • Select-Object
  • New-Object

Alright, thanks. I'll test this tomorrow morning when I have a Windows 10 VM at hand :)

Just tested it and it really seems that you need to import the modules (at least, for current PRTG versions). Just as a quick note, this works, too:

Import-Module @("Microsoft.PowerShell.Management","PSDiagnostics")

Nevertheless, the execution time is horrible... Windows 8.1 with 402ms vs. Windows 10 taking 4.9 seconds ;(

We'll look into it!

Then at least it's not a problem of the Windows update. I presume you installed the Windows from scratch.

Yeah, aweful runtime, so I'm only importing the necessary modules...

New OS new challenge... :-)

Hello Guys,

just out of curiosity, any news on this case?

We've changed the execution of PowerShell sensors (currently internal canary) so it will load the modules according to the PowerShell version: 

if ($PSVersionTable.PSVersion -ge (new-object 'Version' 5,0)) { Import-Module Microsoft.PowerShell.Management; Import-Module Microsoft.PowerShell.Utility};

This should also work with your existing scripts :)
