Logical Disk Performance counter for cluster shared volume on Hyper-V

Question

Hello All,
I am trying to collect counters like latency, queuelength from Win32_PerfFormattedData_PerfDisk_LogicalDisk WMI class.
Output of "Name" attribute for logical disks in this class as below:
Name: _Total
Name: C:
Name: E:
Name: HarddiskVolume1
Name: Q:
Name here doesn't show the actual label so I queried Win32_Volume class and wanted to join with performance WMI class. Out put of Win32_Volume is as below:
Caption: E:\
Label: New Volume
Name: E:\
Caption: Q:\
Label: Quorum
Name: Q:\
Caption: C:\
Label: Voume C
Name: C:\
Caption: F:\
Label: SAN
Name: F:\
Please note that "Name" attribute matches for all except one with label "SAN". This is cluster shared volume and "Name" attribute value is "HardDiskVolume1" in Win32_PerfFormattedData_PerfDisk_LogicalDisk class.
Is this is a configuration issue or any other alternative to get volume label and corresponding performance counters.
Thanks in advance

Hi Udupa,
I haven't found a better way, if you want to combine the two script, please refer to the script below:
$output=@()
$volumes = gwmi Win32_Volume
foreach($volume in $volumes){
$match=($volume.name).TrimEnd("\")
$counter=gwmi Win32_PerfFormattedData_PerfDisk_LogicalDisk |where{$_.name -eq $match}
$Object = New-Object PSObject
$Object | add-member Noteproperty name $volume.name
$Object | add-member Noteproperty label $volume.label
$Object | add-member Noteproperty AvgDiskQueueLength $counter.AvgDiskQueueLength
$output += $Object
$output
I hope this helps.
