NAME

       faultstat - report page faults

SYNOPSIS

       faultstat [options] [delay [count]]

DESCRIPTION

       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.
