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:


and to disable them, use


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.
