I've got a [`Connect-vCenters` function](/logging-in-to-multiple-vcenter-servers-at-once-with-powercli/) that I use to quickly log into multiple vCenters at once. That then enables me to run a single query across the entire landscape - but what query? There isn't really a direct way to get datacenter information out of the results generated by `Get-VM`; I could run an additional `Get-Datacenter` query against each returned VM object but that doesn't sound very efficient. What I came up with is using `Get-Datacenter` to enumerate each virtual datacenter, and then list the VMs matching my query within: ```powershell $linuxVms = foreach( $datacenter in ( Get-Datacenter )) { Get-Datacenter $datacenter | Get-VM | Where { $_.ExtensionData.Config.GuestFullName -notmatch "win" -and $_.Name -notmatch "vcls" } | ` Select @{ N="Datacenter";E={ $datacenter.Name }}, Name, Notes, @{ N="Configured OS";E={ $_.ExtensionData.Config.GuestFullName }}, # OS based on the .vmx configuration @{ N="Running OS";E={ $_.Guest.OsFullName }}, # OS as reported by VMware Tools @{ N="Powered On";E={ $_.PowerState -eq "PoweredOn" }}, @{ N="IP Address";E={ $_.ExtensionData.Guest.IpAddress }} } $linuxVms | Export-Csv -Path ./linuxVms.csv -NoTypeInformation -UseCulture ``` This gave me a CSV export with exactly the data I needed.
