How do I get Provisioned information from Datastores using Powershell

I have two main VMware environments, back-end and customer facing and I have vKernel monitoring on the customer facing environment. Each day I get a cool report, Capacity Monitor Datastore Statistics Report, which gives me some useful information (total space, allocated space, free space, commited %, utilized %). My experience with powershell is related to Exchange and not VMware so all the commands available are new and I am just learning them. So far I have not found a way to get this same type of information (very useful with thin provisioned disks) using powershell.
 
I see that get-datastore will give me some of the information but nothing related to the ‘over’ allocated space of each datastore (i.e. 2 TB lun with 2.7 TB allocated and 750 GB free). I am hoping someone here can point me in the direction to where I can find this information/command(s) in powershell? Thank you for your time.

this script is from our toolbox, for find thin provisioned disks, i'm sure it could be adapted with enough time, using datastore sizes etc

 
# DisplayThinnies.ps1
#
# Displays Virtual Machines and templates that are using thin-provisioned "thin and crispies" virtual disks.
 
 
$vmtp = Get-VM
$vmtp += Get-Template
 
foreach($vm in $vmtp | Get-View){
  foreach($dev in $vm.Config.Hardware.Device){
    if(($dev.GetType()).Name -eq "VirtualDisk"){
      if($dev.Backing.ThinProvisioned -eq $true) {
        $vm.Name + "`t" + $dev.Backing.FileName
      }
    }
  }
}

Thank you for your response, I always appreciate people sharing the scripts they spend time on creating.

I am still curious if you or anyone might know the command(s) I would need to use to get those provisioned sizes of the datastores.  I've done searches using all the search criteria I can think of and have no luck so far in finding anything useful.  VMware's site isn't quite as useful as I had hoped when it comes to the powershell commands.

Again, thanks...

Ok, I have another thought on how to get this information.

Is there a way I can get the Allocated (Provisioned) space per VM?

Have you looked at the The VMware Community PowerPack

This has VM Guest Disk sizes, and if this isn't in your VMware Toolbox it should be!

http://www.vmware.com/solutions/cloud-computing/public-cloud/vcloud-express.html

and also VMware Labs VMwarte Guest Console

(another one for the Toolbox!)
