To all my readers I want to thank you! Over the last couple of years I've gotten lots of great feedback and comments on this blog. It has been read over 386,000 times as of 2/13/2011. I hope you'll join me on my new blog where I hope to put out more real numbers, cover more performance topics, and give...

Hard to believe it has been eight months since my last post. I've been deep into Windows Sercurity and Reliabiltiy and was fortunate enough to have a chance to contribute to one of the two features I'm briefly blogging about today - RemoteFX. So what are RemoteFX and Dynamic Memory? RemoteFX is...

Now that Hyper-V has been in the market for over 9 months a common question that has come my way is “what should I monitor?” This question has been asked for a couple of reasons such as; How do I know if my machine is overloaded? How can I figure out what resources were used so I know what to bill? These...

There are a couple of performance counter sets in Hyper-V that show memory usage. These counters tend to show memory used by one component of the system and the "Hyper-V VM Vid Numa Node" counter set is no different. This counter set is intended to show memory used by the Virtual Infrastructure Driver...

There are a number of groups building management software (OEMs, Microsoft, …) for Hyper-V which is cool to see. A common ask from these teams has been around reading and computing VM CPU usage. The following is an example of how to compute Hyper-V guest processors usage. You can use the same formula...

The “Hyper-V Hypervisor Virtual Processor” and “Hyper-V Hypervisor Root Virtual Processor” counter sets have the same counters. The only difference between the two is the ““Hyper-V Hypervisor Root Virtual Processor” contains counters for only the Root Virtual Processors (VP’s) whereas “Hyper-V Hypervisor...

This is one of the most important counter set in all of Hyper-V. It is also one of the few counter sets that is not impacted by clock skew ( http://blogs.msdn.com/tvoellm/archive/2008/03/20/hyper-v-clocks-lie.aspx ) Before digging into the counter set it is important to understand a Logical Processor...

The “Hyper-V Hypervisor” counter set is a good place to start when looking for overall system information and what is running under Hyper-V. Hyper-V Hypervisor counter set counters: · Logical Processors – These are the number of cores / HT that the hypervisor is managing. If you have a dual proc...

[[ ***IF YOU HAVE SPECIFIC QUESTIONS ON PERFORMANCE COUNTERS YOU WANT ANSWERED PLEASE POST A REPLY WITH THE QUESTION***]] 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...
