mshypervserver.vbs - vbscript script by ActiveXperts Software
mshypervserver.vbs checks whether MS Hyper-V Server is running; it checks services, processes and performance counters.
Use mshypervserver.vbs directly from ActiveXperts Network Monitor; in the Manager's 'Monitor' menu, select 'New Check (Script)' and select mshypervserver.vbs. Configure the required parameter, or press 'Load a working sample'.
In ActiveXperts Network Monitor, Administrators can use three different scripting languages: Powershell, VBScript and SSH.

' Checks if HyperV is running; it checks the HyperV services ans HyperV processes
