Remote PowerShell Script for Skype

Hi there

I'm trying to monitor our Skype for Business Servers - without much luck though :( How can I get my script to be run on the remote server itself?

Script:

$query = Get-CsWindowsService RTCMEDSRV
[string]$result = $query.ActivityLevel

[string[]]$splitResult = $result.Split('=,')[1,3,5,7]

[int]$InboundCalls     = $splitResult[0] -as [int]
[int]$OutboundCalls    = $splitResult[1] -as [int]
[int]$InboundPriCalls  = $splitResult[2] -as [int]
[int]$OutboundPriCalls = $splitResult[3] -as [int]

$InboundTotalCalls     = $InboundCalls + $InboundPriCalls
$OutboundTotalCalls    = $OutboundCalls + $OutboundPriCalls

Write-Output $InboundTotalCalls

PRTG Error: Response not well-formed: "(Get-CsWindowsService : The term 'Get-CsWindowsService' is not recognized as the name of a cmdlet, function, script file, or operable program. Check the spelling of the name, or if a path was included, verify that the path is correct and try again.
