Hyper-V Guest VM perfomance monitoring

Question

I want to find out which VMs are creating excess IO on the CSV datastores that result in high latency. I see that latency on 10K datastores goes higher then 80 ms at times.

VM's reside on common 10K disk group datastores, so when the disk group is impacted, many VM experience problems. The problem with monitoring individual VMs with perfmon is that there are many 10K datastores with VMs that are impacted at the same time

Which tools should I use to looks at statistics at VM level ?
What metrics should I look at?

Hi,

Thank you for your posting!

Based on your descriptions, I have two tools for you to monitor VM level performance in a cluster:

1) Performance Monitor will always be your choice and you can add counters that you want to better meet your customized needs. Here is the article:

(PS. This article also works for versions other than windows 10)

2) You can also use our Windows Admin Center which can automatically show you the top VMs consuming the most CPU and memory resources. Here are the articles on how to use this service:

In addition, I have found an article about CSV performance related which can better help you monitor and manager your use of CSV and related VMs, including the metrics details you may be interested to:

Thank you for your support! Wish you have a wonderful day! : )
