NT Memory Performance Group

The NT Memory Performance group contains memory and paging performance counters and statistics that let you track the memory usage of your system.

Class: ntMemoryPerf

You can determine the following information using the NT Memory Performance group:

Amount of available virtual memory (ntAvailKBytes)
Number of KB being used by the system cache and the maximum used (ntCacheKBytes, ntCacheKBytesPeak)
Number of cache and page faults (ntCacheFaults, ntPageFaults)
Amount of virtual memory committed without expanding paging file (ntCommitLimit, ntCommittedKBytes)
Number of page faults filled with zeros (ntDemandZeroFaults)
Number of free page table entries (ntFreeSysPageTableEntries)
Number of page reads and writes (ntPageReads, ntPageWrites)
Number of pages read from disk and written to disk (ntPagesInput, ntPagesOutput, ntPages)
Number of kilobytes in the paged and nonpaged pools (ntPoolNonPagesKBytes, ntPoolPagesKBytes)
Number of calls to allocate space in the system pool (ntPoolPagedAllocs)
Size of paged pool resident (ntPagedResidentKBytes)
Amount of memory in global disk cache (ntSysCacheResidentKBytes)
Amount of system code total bytes and system code resident in core memory (ntSysCodeTotalKBytes, ntSysCodeResidentKBytes)
Amount of driver memory and resident driver memory (ntSysDriverTotalKBytes, ntSysDriverResidentKBytes)
Number of page faults resolved by recovering pages in transition (ntTransistionFaults)
Number of page faults satisfied by copying the page (ntWriteCopies)
