Hi , I wonder to know if it is possible to monitor windows activation status with prtg, I found a kb post explaining this but I want it to be elaborated more (https://helpdesk.paessler.com/en/support/solutions/articles/62403-windows-activation-status) I know that I've to create a wmi sensor targeting Win32_WindowsProductActivation class Actually this is exactly what I've done : 1 - created a .wql file using this syntax : SELECT * FROM Win32_WindowsProductActivation 2 - created a WMI Custom Sensor , and the selected the WQL File as I saved in Custom Sensors , mentioned before but I got this message : 80041010: The specified class is not valid. what Should I do know? thank you

Hi there,

The error message "80041010: The specified class is not valid." means that the class cannot be found on the remote system. Are you able to scan it via the WMI Tester (https://www.paessler.com/tools/wmitester )?

Best regards.

Hi there,

Then I am afraid that this is not possible to monitor this information - as long as the class does not exist.

Please note that the KB-Article mentioned is already 5 years old, so newer operating systems might have a new class.

Best regards.

Are you sure? you mean there's no where in PRTG I could check the activation status of my servers? could you please tell me if there is a new class I can use?

Hi there,

PRTG itself does not have any native sensors that allow you to monitor this. If there is a new class is unknown to use, please note that WMI is developed/supported by Microsoft - we just use it. :)

Best regards.
