Hyper-V Guide: Configure Resource Metering

Resource Metering in Hyper-V allows you to monitor the resources a virtual machine is consuming on the host and is primarily for use in chargebacks.

All of the Hyper-V Exam Guide and Notes are available.

Resources

The following PowerShell commands are used in the notes below:

  • Enable-VMResourceMetering – Starts collecting resource utilization data for a virtual machine or resource pool;
  • Set-VMHost – Configures a Hyper-V Host;
  • Measure-VM – Reports resource utilization data for one or more virtual machines;

Overview

  • If no network adapter ACL’s are configured when metering is enabled then they are automatically configured to measure total network traffic;
  • Moving a virtual machine between hosts – through migration – does not affect the collected data;
  • Having resource metering configured has no noticeable performance hit;

Data collection

  • Data collection settings are applied per host to all virtual machines running on it;
  • By default the data is collected once per hour;
  • You can change the data collection frequency for the host using the Set-VMHost PowerShell Hyper-V Cmdlet:

What can be measured?

  • Average CPU (in MHz) over a period of time;
  • Average physical memory usage in MB (this includes the time the VM is off);
  • Minimum memory usage in MB while the VM was running (this is the lowest memory value that was used);
  • Maximum memory usage in MB while the VM was running (this is the highest memory value that was used);
  • Total incoming traffic for a network adapter in MB;
  • Total outgoing traffic for a network adapter in MB;

Network Metering

  • Network metering ACL’s are used to measure traffic between IP ranges so you could exclude all internal IP ranges and only focus on internet traffic for billing;
