Ah yes that was it. I adjusted the thresholds and got some results. If I also want to add the columns for FreeSpace%, ProvisionedSpace% and Uncommitted%
are my calculations correct?
@{N='Freespace%';E={[math]::Round($_.FreespaceGB/$_.CapacityGB*100,1)}},
@{N='ProvisionedSpace%';E={[math]::Round((($_.ExtensionData.Summary.Capacity - $_.Extensiondata.Summary.FreeSpace + $_.ExtensionData.Summary.Uncommitted)/1GB)/$_.CapacityGB*100,1)}},
@{N='UnCommittedGB%';E={[math]::Round(($_.ExtensionData.Summary.Uncommitted/1GB)/$_.CapacityGB*100,1)}},
Thanks so much
