SOLVED: Easily Determine The Health Status of a HyperV Virtual Machine

If you work with HyperV there will come a time when you need to run some basic PowerShell commands to find out how health your HyperV Virtual Machines really are.

1 – Commands To Determine HyperV Health

Easy command to check all of the HyperV VMs at once:

In a POWERSHELL as an ADMINISTRATOR use:

Get-WmiObject -Namespace root\virtualization\v2 -ComputerName "<your host server name>" -Query "Select * From Msvm_ComputerSystem Where ElementName='<vm name you want to check>'"
