This read-only integer reports the rate at which page faults occur in the threads executing within this specific process, occurring when a thread references a virtual memory page not currently in its working set, though this does not necessarily mean a disk fetch is required if the page is already elsewhere in memory. An admin watches this per-process fault rate to identify an application whose memory access pattern is causing excessive faulting. For example, a process with a persistently high cpqOsProcessPageFaultsPerSec compared to its peers could be operating with an undersized working set relative to its actual memory needs.
