How to Configure Command Notification in SCOM 2012 with PowerShell script.

Here’s a step by step tutorial how to create a Command Notification which calls a PowerShell script. The step by step is in SCOM 2012, but can also be used in SCOM 2007 R2.

 

Step 1 Create PowerShell script

Create the following script and test:

 

Param ([ String ] $AlertName ,[ String ] $SubscriptionID )

$Logstring = $AlertName + " " + $SubscriptionID
$Logfile = "c:\temp\LogAlerts.log"
$DateTime = Get-Date - Uformat "%y-%m-%d %H:%M:%S"
$Logstring = $DateTime + " " + $Logstring
Add-content $Logfile - value $Logstring

Command line parameters: "c:\temp\LogAlerts.ps1" '$Data/Context/DataItem/AlertName$' '$MPElement$'
