Overview of NUMA locality per VM per cluster.

NUMA statistics per VM per cluster. According to Yellow-Bricks the LocalityPct (N%L) should preferably be above 80%. With this script we check our environment to see what the LocalityPct (N%L) per VM is.

Be aware this is just a single snapshot in time and is meant to give you a quick glance, based on the assumption that clusters that have all VMs steady above 95% locality, will not turn bad in a few minutes.

My script is based on Get-EsxtopAPI.ps1 by William Lam.
