Tony Voellm: In the next few posts I’ll be covering Hyper-V performance counters. There have been a lot of changes from Beta -> RC -> post RC. In Beta the counters sets for Hyper-V were not grouped under a common namespace. This made them hard to find. In RC the counters are grouped under the “Hyper-V” namespace. That is each counter set starts with “Hyper-V.” For example “Hypervisor Logical Processors” are now “Hyper-V Hypervisor Logical Processors.” The prefix causes all the Hyper-V counters to be grouped together.

Post RC you will see some counter sets get renamed and a few like “Hyper-V VMMS Task Manager Summary" have been removed because they did not provide a lot of value. The most notable renaming was “Hyper-V Hypervisor …” rate counters where “/ sec” has been appended to to make it clear they are a rate. You will also see some counters have been removed.
