.TH pridist.d 1m "$Date: 2015/09/30 22:01:09 $" "USER COMMANDS"
|
|
.SH NAME
|
|
pridist.d \- process priority distribution. Uses DTrace.
|
|
.SH SYNOPSIS
|
|
.B pridist.d
|
|
.SH 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 particular PID.
|
|
|
|
Since this uses DTrace, only the root user or users with the
|
|
dtrace_kernel privilege can run this command.
|
|
.SH OS
|
|
Solaris
|
|
.SH STABILITY
|
|
stable.
|
|
.SH EXAMPLES
|
|
.TP
|
|
This samples until Ctrl\-C is hit.
