Configuring resource metering

Resource metering is a Windows PowerShell–based feature in Windows Server 2012 R2 Hyper-V that enables administrators to document VM usage by using a variety of criteria.
There are various reasons why organizations might want to track the use of VMs. For large corporations, it might be a matter of internal accounting and controlling ongoing expenses, such as wide area network (WAN) bandwidth. For service providers, it might be necessary to bill customers based on the VM resources they use.
Resource metering uses Windows PowerShell cmdlets to track a variety of performance metrics for individual VMs, including the following:

- CPU utilization
- Minimum, maximum, and average memory utilization
- Disk space utilization
- Incoming and outgoing network traffic

Resource metering statistics remain consistent, even when you transfer VMs between host systems by using Live Migration or move VHD files between VMs.

To use resource metering, you must first enable it for the specific VM that you want to monitor by using the Enable-VMResourceMetering cmdlet with the following syntax:
Enable-VMResourceMetering –VMName <name>
Once you have enabled metering, you can display a statistical report at any time by using the Measure-VM cmdlet with the following syntax:
Measure-VM –VMName <name>
In addition to metering resources for entire VMs, administrators can also create resource pools that enable them to monitor specific VM components, such as processors, memory, network adapters, and VHDs. You create a resource pool by using the New-VMResourcePool cmdlet and then enable metering for the pool by using Enable-VMResourceMetering.
By using techniques such as pipelining, administrators can use the resource metering cmdlets to gather data on VM performance and export it to applications or data files.
