.NET PerformanceCounter for Hard Faults/sec

Question

Vista's Resource Monitor includes a reading for "Hard Faults/sec". Is there an equivalent performance counter I can use in C# to get this reading? I've tried the "Page Faults/sec" under the memory category, but that appears to be something different.

Answer 1

A hard fault is the same as a page fault.

Source: " Windows Vista Performance and Reliability Monitoring Step-by-Step Guide ".

See section Resource View details , Label Memory (the 4th table):

A hard fault (also known as a page fault) occurs when the page of the referenced address is no longer in physical memory and has been swapped out or is available from a backing file on disk.

Answer 2

Page faults/sec measures both Hard Faults and Soft Faults. The counter named Transition Faults/sec measures Soft Faults. Thus, to get the Hard Faults you should subtract Transition Faults/sec from Page Faults/sec
