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.
The goal of the changes has been to simplify the counters and provide a very useful core that are easy to find. Improvements have also been made to make the counters more accurate.
The “Performance Counter” blog entries will focus on what you will see post RC but it should not be too hard to apply what is discussed to RC or Beta.
