I would have thought that the above library can be reached using the following: https://msdn.microsoft.com/en-us/library/aa394308(v=vs.85).aspx
Get-WmiObject -Query "SELECT avgdiskbytesperread FROM win32_PerfRawData_PerfDisk_PhysicalDisk"
But obviously it does not as it's no where near what I'm seeing using the Windows Performance Monitor.
Where can I find it?
I was looking at the wrong place the entire time...
All relevant Disk based Performance Counters can be found here:
Get-WmiObject -Query "SELECT * from Win32_PerfFormattedData_PerfDisk_PhysicalDisk"
