How to get the VMware view agent version of VMs with powercli

Just query the VM with get-vm and add | Select UsedSpaceGB.

For example, you could type:

get-vm | Select Name, UsedSpaceGB, ProvisionedSpaceGB

I'm not exactly sure how you set those in the first place but you can remove the variables (rather than null them) using the following.

1) First check what you have with in a fresh PowerCLI session with Get-Variable (you should see something like this but likely a value for a server)

Name                           Value
----                           -----
global:DefaultVIServer         
global:DefaultVIServers        {}

2) Remove each using Remove-Variable DefaultVIServer and Remove-Variable DefaultVIServers 3) Try connecting to the correct vCenter with Connect-VIServer yourvcenter.domain.com*

If you keep having variables reset, it's possible you've customized something in the startup file (C:\Program Files (x86)\VMware\Infrastructure\vSphere PowerCLI\Scripts\Initialize-PowerCLIEnvironment.ps1) so you might need to replace/remove the entries there (never tried that, just taking a guess)

PS. Sorry about formatting messs, still getting used to the format
