#!/usr/sbin/dtrace -s /* * pridist.d - process priority distribution. * Written using DTrace (Solaris 10 3/05) * * 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. * * $Id: pridist.d,v 1.1.1.1 2015/09/30 22:01:09 christos Exp $ * * USAGE: pridist.d # hit Ctrl-C to end sampling * * 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 * * SEE ALSO: * DTrace Guide "profile Provider" chapter (docs.sun.com) * dispadmin(1M) * * PORTIONS: Copyright (c) 2005 Brendan Gregg. * * CDDL HEADER START * * The contents of this file are subject to the terms of the * Common Development and Distribution License, Version 1.0 only * (the "License").
