NAME

sampleproc - sample processes on the CPUs. Uses DTrace.

SYNOPSIS

sampleproc [hertz]

DESCRIPTION

This program samples which process is on each CPU, at a particular configurable rate. This can be used as an estimate for which process is consuming the most CPU time.

Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

Sample at 100 hertz,: # sampleproc
Sample at 400 hertz,: # sampleproc 400

FIELDS

PID: process ID
COMMAND: command name
COUNT: number of samples
