Hello:

Encounter a more difficult problem, my environment is a resource monitoring in the failover cluster in Windows 2008 R2, through sub-partition to complete the partition of this sub?

If the only monitor in the parent partition, then it would be a very bad problem, because the child partition will drift, unable to confirm the sub-partition in which the parent partition

Ben,

Do you have any suggestions regarding monitoring disk subsystem monitoring? For example if my child guest machines are actually on a SAN, where would be the best place to monitor disk performance for the child?

You'll actually find the same case with VMWare. IMHO, people should not keep looking at Virtual Guests the same as they do as physical machines. Another item in addition to CPU/Memory is Time, since the processor on a guest is not always active then time can become a problem keeping in true sync which can cause issues with real-time/time sensitive applications.

any good samples regarding WMI,VirtualServer and Visual C++

Ben,

Love reading your posts! Thanks for the great info!

My only question about this explanation of the differences between the two is if it's that complicated and doesn't show the true values in near real-time, then why not use a scale (i.e. Great, Good, OK, Poor, Critical). Just a thought. Perhaps then, it could be more manageable and more reflective. Then, we can pop over and see what threads are causing the Poor rating. Again, just a thought.

This sounds like a bad explenation for a bug. I just hope it doesn't hide a serious design nor archiecture problem in Hyper-V. Time will tell though...

"The first part of the answer is that when you run Task Manager in the parent partition (remembering that it is "just another partition on the system") it knows nothing about CPU usage that is happening in the hypervisor or in child partitions". Is it the same way for RAM? I can clearly see all my 4 GB of RAM on my laptop with Hyper-V. What is the differens between CPU and RAM with parent partition and Hyper-V?
