When trying to add a Hyper-V Virtual Machine sensor I am unable to. Under the Virtual Machine Settings I see "No Virtual Machine available". I have 4 VMs running on this host. Other Perf Counters/WMI sensors seem to be fine on this server.

I have run the following from the WMI Tester: Namespave: root\virtualization SELECT Name,ElementName,Description FROM Msvm_ComputerSystem WHERE ProcessID<>NULL

I get Error: 80041010: The specified class is not valid.

I have looked in the KB threads but found nothing satisfactory. I am currently running 16.3.26.6385 on this cluster.

Hello there,

The used namespace in the tester might be indeed wrong, in Server 2012 and newer it is root\virtualization\v2.

The so-called "Meta Scan" that initially tries to list the VMs uses this query: SELECT Name FROM Win32_PerfRawData_IdePerfProvider_HyperVVirtualIDEControllerEmulated

Though for this query you might need to set root\cimV2 as namespace. What do you get with this query in the tester?

Also try this query:

SELECT ElementName,EnabledState FROM Msvm_ComputerSystem WHERE name LIKE 'VMGUID'

This the query a running sensor would then perform. Here's how to retrieve the VMs GUID.

Kind regards,

Erhard

Hi Erhard,

Here are the results:

---------------------------------------------------------------------------------------------------- Set namespace to: root\virtualization\v2

SELECT Name FROM Win32_PerfRawData_IdePerfProvider_HyperVVirtualIDEControllerEmulated

Result: Specified class is not available

SELECT ElementName,EnabledState FROM Msvm_ComputerSystem WHERE name LIKE 'VMGUID'

Result: Blank response, no data returned but no error

----------------------------------------------------------------------------------------------------

---------------------------------------------------------------------------------------------------- Changing the namespace to root\cimV2

SELECT Name FROM Win32_PerfRawData_IdePerfProvider_HyperVVirtualIDEControllerEmulated

Result: I get a list of VMs on each host

SELECT ElementName,EnabledState FROM Msvm_ComputerSystem WHERE name LIKE 'VMGUID'

Result: Specified class is not available

----------------------------------------------------------------------------------------------------

Still, trying to add the VM sensor to the two servers that returned a list of VMs I still get "No Virtual Machine Available".
