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.
