VMWare CLI

Very cool tool to find the PowerCLI Code you need 

List of Performance Counters


list of commands related to stats
Get-Command -Module "VMware.VimAutomation.Core" *stat*


Get a list of stats available for a vm or host
Get-StatType -Entity servername 
Get-StatInterval
Get-StatType -Entity servername -Interval "Past Day"


Get-vm servername | Get-Stat -Stat mem.active.average -Start (Get-Date).AddHours(-2)-IntervalMins 5

Peak memory usage over past 24 hours in gb
(Get-vm servername | Get-Stat -Stat mem.active.average -Start (Get-Date).AddHours(-24) | Measure-Object -Property Value -Maximum).Maximum * 1kb / 1gb

If you change the interval units you can get older data
Get-vm servername | Get-Stat -Stat mem.usage.average -Start (Get-Date).AddHours(-168) -IntervalMins 60 | sort timestamp | select -First 5

CPU Ready

#% CPU Ready = (CPU Ready / stat interval in milliseconds ) * 100
#( 30 min x 60 seconds * 1000 = 1800000 milliseconds ) * 100 to get percent, so we use 18000 as our divisor

PowerCLI property for vSphere client GUI Cluster "Current Failover Capacity"
This seems to be the right property $cluster.ExtensionData.Summary.CurrentFailoverLevel
Get-Cluster | select name, @{Name="Current Failover Capacity"; Expression={$_.ExtensionData.Summary.CurrentFailoverLevel}} | ft -auto
