Getting current resource utilization

We can use liveoptics for getting current resource utilization such as:

  • 95% IOPS
  • Peak and 95% CPU usage
  • Peak and 95% memory usage
  • Overall storage usage

etc. for a physical host, hypervisor such as Hyper-V or ESXi, etc.

This information is critical if we are trying to size a new environment during migration - P2V or V2V or hardware refresh

We can signup for live optics from https://www.liveoptics.com/ But for personal use we may not get performance data. If we get invitation of using this from an OEM (eg VMWare) then we get full features. In that case we should login into portal at least once every 90 days to keep account active.

Once we run live optics in an environment for at least 48 hours / ideally 1 week or more, we can export the information in form of presentations. Those presentations from live optics have detailed resource usage information about the environment which was monitored. We can do this live in production without any significant performance impact during observation period.
