Get-Datacenter | Select @{N = 'datcentername'; E = {$_.Name -replace '-','' }}, @{N = 'Cluster_Name'; E = {$datacenter.name}}, @{N = 'VM Count'; E = {( get-vm | where-object { $_.powerstate -eq "poweredOff"}).Count}}
how come this is adding the counts instead of breaking them out per count by Datacenter ?
