sampleproc(1m)                                  USER COMMANDS                                 sampleproc(1m)



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 the root user or users with the dtrace_kernel  privilege  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

       PERCENT
              percent of CPU usage


BASED ON
       /usr/demo/dtrace/prof.d
