pridist.d(1m)                                   USER COMMANDS                                  pridist.d(1m)



NAME
       pridist.d - process priority distribution. Uses DTrace.

SYNOPSIS
       pridist.d

DESCRIPTION
       This  is  a  simple  DTrace script that samples at 1000 Hz which process is on the CPUs, and what the
       priority is. A distribution plot is printed.

       With priorities, the higher the priority the better chance the  process  (actually,  thread)  has  of
       being scheduled.

       This idea came from the script /usr/demo/dtrace/profpri.d, which produces similar output for one par-ticular particular
       ticular PID.

       Since this uses DTrace, only the root user or users with the dtrace_kernel  privilege  can  run  this
       command.

EXAMPLES
       This samples until Ctrl-C is hit.
              # pridist.d


FIELDS
       CMD    process name

       PID    process ID

       value  process priority

       count  number of samples of at least this priority


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

EXIT
