Do you need to find which VMs have Change Block Tracking (CBT) enabled and which have it disabled? Here’s a PowerShell commandlet that gives you a list of VMs with CBT enabled, run it on your VMware vCenter server:
Get-VM | Where-Object{$_.ExtensionData.Config.ChangeTrackingEnabled -eq $true}
To get a list of VMs with CBT disabled, change the commandlet to say false instead of true.
