SCOM - SCRIPT - Fonction powershell pour lister toutes les instances d'une machine

Le script ci-dessous intègre la requête SQL de récupération des instances d'une machine, sous forme de fonction.

# SCRIPT THAT QUERY SCOM DATABASE TO GET ALL INSTANCES OF ALL CLASSES FOR A GIVEN COMPUTER ($TargetAgent)
# $TargetComputer must be Short name of computer because we look for this specific string in name, displayname and path of instances.

param(
#Short name of computer
