The Outside View of VMs Layer

This layer provides the host operating system’s view of the resource usage levels of each of the virtual desktops hosted on it. Using the information reported by this test, administrators can:

  • Determine which of the virtual desktops is taking up more resources (CPU, memory, network, or disk) than the others. This information can help with load balancing or capacity planning. For example, if one of the virtual desktops is receiving a very high rate of requests compared to the others, this guest may be a candidate for migration to another Acropolis server, so as to minimize the impact it has on the other guests on the current Acropolis server.
  • Determine times when sudden or steady spikes in the physical resource utilization are caused by the guest machines
  • Track the overall status of the virtual machines - how many are registered, which ones are powered on, and at what times, etc.
  • Understand how resources are shared amongst all available resource pools, and identify resource pools that have been over-utilized.
