Try something like this
Get-Cluster|Get-ResourcePool|Select@{N="Cluster";E={Get-View$_.ExtensionData.Owner|Select-ExpandPropertyName}},
@{N="Parent";E={$_.Parent.Name}},
@{N="ResourcePool";E={$_.Name}},
CpuSharesLevel,MemSharesLevel
I included a Parent property, since you can have nested resourcepools and to cope with the hidden Resources resourcepool.
I just included the share levels, but any other of the share properties can be included as well
