Hyper-V performance counters in Windows Server 2008 are displayed incorrectly or report incorrect data when you remotely query the counters from a Windows Server 2003-based computer
Article ID: 967124 - View products that this article applies to.
When you use the performance monitor on a Windows Server 2003-based computer to query Hyper-V related performance counters on a Windows Server 2008-based computer that has the Hyper-V role enabled, the following problems occur.
Problem 1The following objects are missing:
Problem 2Under the Hyper-V Hypervisor Logical Processor object, the following issues occur:
Problem 3Under the Hyper-V Hypervisor Root Virtual Processor object, the following issues occur:
The way performance monitor determines base counters is incorrect, which causes dependent counters not to show up.
Note If the provider is not running on Windows Server 2008, you will not see the performance object on the remote performance monitor that is running on Windows Server 2003 even though the object is displayed in the performance monitor in Windows Server 2008. This is by design.
For example, the "Hyper-V Virtual Storage Device" object shows up in the performance monitor in Windows Server 2008. However, when you select the counters, they aren't added. This is because a SCSI Controller is not installed with a disk. Therefore, the counters do not show up on the remote computer that is running Windows Server 2003.
A hotfix is available to resolve this problem. You need to install this hotfix on the Windows Server 2008-based computer that has the Hyper-V role enabled.
