Report page faults
Usage
faultstat [options]

Overview
faultstat reports the major and minor page fault activity of processes.
If a delay and count are not specified, a snapshot of the current page fault activity is displayed.
If a delay in seconds is specified, faultstat will periodically show any per-process page fault changes. This will run indefinitely until a SIGINT is caught. Specifying count will repeat the periodic output count number of times.
