O asterisco significa "Todas as instâncias", que inclui _Total quando aplicável.
Perfmon é provavelmente o lugar mais fácil para ver os contadores e ver o que está disponível em seu sistema.
A partir da documentação para o typeperf :
•Counter path format
The general format for counter paths is as follows: [\Computer]\object[parent/instance#index]\counter] where:
The parent, instance, index, and counter components of the format may contain either a valid name or a wildcard character. The computer, parent, instance, and index components are not necessary for all counters.
You determine the counter paths to use based on the counter itself. For example, the LogicalDisk object has an instance index, so you must provide the #index or a wildcard. Therefore, you could use the following format:
\LogicalDisk(*/*#*)\*
In comparison, the Process object does not require an instance index. Therefore, you could use the following format:
\Process(*)\ID Process
The following is a list of the possible formats: ◦ \machine\object(parent/instance#index)\counter
◦ \machine\object(parent/instance)\counter
◦ \machine\object(instance#index)\counter
◦ \machine\object(instance)\counter
◦ \machine\object\counter
◦ \object(parent/instance#index)\counter
◦ \object(parent/instance)\counter
◦ \object(instance#index)\counter
◦ \object(instance)\counter
◦ \object\counter
Edit: Ah, e não se esqueça de verificar Get-Counter em Powershell:
PS C:\> (Get-Counter -ListSet Memory).Paths
\Memory\Page Faults/sec
\Memory\Available Bytes
\Memory\Committed Bytes
\Memory\Commit Limit
\Memory\Write Copies/sec
\Memory\Transition Faults/sec
\Memory\Cache Faults/sec
\Memory\Demand Zero Faults/sec
\Memory\Pages/sec
\Memory\Pages Input/sec
...
The second command gets the path names that include "cache".
PS C:\> (Get-Counter -ListSet Memory).Paths | Where {$_ -like "*Cache*"}
\Memory\Cache Faults/sec
\Memory\Cache Bytes
\Memory\Cache Bytes Peak
\Memory\System Cache Resident Bytes
\Memory\Standby Cache Reserve Bytes
\Memory\Standby Cache Normal Priority Bytes
\Memory\Standby Cache Core Bytes
