561N/A * priclass.d - priority distribution by scheduling class. 561N/A * Written using DTrace (Solaris 10 3/05) 561N/A * This is a simple DTrace script that samples at 1000 Hz the current 561N/A * thread's scheduling class and priority. A distribution plot is printed. 561N/A * With priorities, the higher the priority the better chance the thread 561N/A * has of being scheduled. 561N/A * produces similar output for priority changes, not samples. 561N/A * $Id: priclass.d 3 2007-08-01 10:50:08Z brendan $ 561N/A * USAGE: priclass.d # hit Ctrl-C to end sampling 561N/A * value process priority 561N/A * count number of samples of at least this priority 561N/A * Also printed is the scheduling class, 561N/A * FSS fair share schedular 561N/A * PORTIONS: Copyright (c) 2006 Brendan Gregg. 561N/A * The contents of this file are subject to the terms of the 561N/A * Common Development and Distribution License, Version 1.0 only * (the "License").
