On Windows, we can easily get the description of a performance counter by using the perfmon
utility. Take a look at the description section in below snapshot.
Is it possible to get this info from Powershell's get-counter
cmdlet?
It appears that information is stored in the registry at (for English):
HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009 in the multi-string key Help
So since PowerShell can use the Registry as a Provider, yes you can get this information technically although it's a bit ugly:
(Get-ItemProperty -Path "HKLM:\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Perflib\009").Help
That will pull all the text from the help entry, which you can then filter through with pipes/Select-String/various string methods, Where clauses/etc.
