Q: How do I enable and view the Windows Server 2012 Hyper-V metric information?

A: Windows Server 2012 introduces the ability to track certain metrics for virtual machines (VMs):

• Average CPU usage, measured in megahertz over a period of time
• Average physical memory usage, measured in megabytes
• Minimum memory usage (lowest amount of physical memory)
• Maximum memory usage (highest amount of physical memory)
• Maximum amount of disk space allocated to a virtual machine
• Total incoming network traffic, measured in megabytes, for a virtual network adapter
• Total outgoing network traffic, measured in megabytes, for a virtual network adapter

To start the gathering of metric data for a VM, you use the Enable-VMResourceMetering Windows PowerShell cmdlet:

Enable-VMResourceMetering -VMName <virtual machine name>

To reset the counters, use this command:

Reset-VMResourceMetering 

and to disable them, use

Disable-VMResourceMetering

To view the collected metrics, use this command:

Measure-VM cmdlet

Notice that in my example below, I pass the output object to the formal list (fl) alias to get full information you see below that (by default a table view is used which does not show all data). There is also a Measure-VMResourcePool cmdlet if resource pools are used.
