Page fault and memory utilization

-
pidstat -r -p <pid> [interval] [count]
-
-
minor_pagefault: Happens when the page needed is already in memory but not
-                 allocated to the faulting process, in that case the kernel
-                 only has to create a new page-table entry pointing to the
-                 shared physical page (not required to load a memory page from
-                 disk).
