Members

cb
The size of the structure, in bytes.

PageFaultCount
The number of page faults.

PeakWorkingSetSize
The peak working set size, in bytes.

WorkingSetSize
The current working set size, in bytes.

QuotaPeakPagedPoolUsage
The peak paged pool usage, in bytes.

QuotaPagedPoolUsage
The current paged pool usage, in bytes.

QuotaPeakNonPagedPoolUsage
The peak nonpaged pool usage, in bytes.

QuotaNonPagedPoolUsage
The current nonpaged pool usage, in bytes.

PagefileUsage
The Commit Charge value in bytes for this process. Commit Charge is the total amount of memory that the memory manager has committed for a running process.

PeakPagefileUsage
The peak value in bytes of the Commit Charge during the lifetime of this process.
