The Outside View of VMs Layer

The Outside View of VMs layer represents the host’s view of the resource usage levels of each of the VM guests hosted on it. Using the information reported by this test, administrators can:

  • Determine which of the VM guests is taking up more resources (CPU, memory, network, or disk) than the others. This information can help with load balancing or capacity planning.
  • 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.
