query for top thin disk vm candidates

[ssauer]

I am looking for some help on a way I can query VC to find VM's that are "wasting a lot of disk" and would be good candidates for migrating to a thin disk. Is there a way to query the vm disk, and what is being consumed and what is being allocated?

There is a nice one-liner to get the VM disk details o my blog here:

http://www.virtu-al.net/2009/03/25/vi-toolkit-one-liner-vm-guest-disk-sizes/

The script is:

ForEach ($VM in (Get-VM |Get-View)){($VM.Guest.Disk |Select @{N=“Name“;E={$VM.Name}},DiskPath, @{N=“Capacity(MB)“;E={[math]::Round($_.Capacity/ 1MB)}}, @{N=“Free Space(MB)“;E={[math]::Round($_.FreeSpace / 1MB)}}, @{N=“Free Space %“;E={[math]::Round(((100 * ($_.FreeSpace))/ ($_.Capacity)),0)}}) | Format-Table}
