FAULTSTAT

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.

	-l		show long (full) command information

-p proclist
