mappings between counters, structure and Task Manager columns – Memory Performance Information (Windows)
Posted by jpluimers on 2018/01/03
I copied the tables from [WayBack] Memory Performance Information (Windows) as even Microsoft managed to let information “disappear” for EOL products (the en-US version already “disappeared”):
System Memory Performance Information
The following table associates memory object performance counters with the data returned by the memory performance functions in the MEMORYSTATUSEX, PERFORMANCE_INFORMATION, andPROCESS_MEMORY_COUNTERS_EX structures, and with the corresponding information displayed by Task Manager.

Process Memory Performance Information
The following table associates process object performance counters with the data returned by the memory performance functions in the MEMORYSTATUSEX, PERFORMANCE_INFORMATION, andPROCESS_MEMORY_COUNTERS_EX structures, and with the corresponding information displayed by Task Manager.
