This is a small powershell script for NSClient to check if Cluster Groups are running on their preferred owner on a Microsoft cluster. Simply add it to you NSClient scripts directory and put the following line in your nsc.ini check_preferred=cmd /c echo scriptscheck_preferred.ps1; exit($lastexitcode) | PowerShell.exe -Command - Don't forget to enable the running of ps1 scripts by powershell! You can do this by starting a powershell as administrator and give the command "Set-ExecutionPolicy Unrestricted" This script was tested with MS SQL Cluster and Filecluster, but should work on any MS cluster.

Great Script!
by diablo2424, March 31, 2018
I love this script, I just made one minor change to the Get-Cluster line.

Original:
Get-ClusterNode $Computer | Get-ClusterGroup | ?{ $_ | Get-ClusterResource }

Modified:
$ClusterGroups = Get-ClusterGroup | Where-Object {($_.Name -ne "Cluster Group")} | Where-Object {($_.Name -ne "Available Storage")}


The new modified version will not display the default "Cluster Group" and "Available Storage" blank clusters, which do not have a preferred owner, causing the script to always read WARNING.

However, being new to NAGIOS and CheckMK, I am unsure as to what define service and define command entries to put into my NAGIOS server config files. Can anyone help me out with that part?
