Dynamic Memory Performance Counter

 

You’ve deployed SP1 on Hyper-V and enable Dynamic Memory. The next question, which performance counter that you should use to monitor the utilization? We often need to check the performance counter and very few people mention on which counter to monitor. Therefore I've decided to compile and put them here.

Other counters (from my previous post):- http://www.ms4u.info/2010/08/measure-performance-of-hyper-v-using.html

Dynamic memory Utilization on Hyper-V Host

Check on “Average Pressure” counter under the “Hyper-V Dynamic Memory Balancer” category.  This gives you a very simple view of the overall memory allocation of your system.

\Hyper-V Dynamic Memory Balancer\Average Pressure

Health:- less than 80%

Warning: 80 –100%

Critical:- more than 100% . Indicated running out of memory on Hyper-V host and virtual machine start to use virtual paging.

Some additional performance counter information which i got it from Greg pos. It may come on handy when you need to understand what each counter do:-

a) Hyper-V Dynamic Memory Balancer- host level memory information

b) Hyper-V Dynamic Memory Balancer VM- VM level memory information
