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

NAME
priclass.d - priority distribution by scheduling class. Uses DTrace. SYNOPSIS
priclass.d DESCRIPTION
This is a simple DTrace script that samples at 1000 Hz the current thread's scheduling class and priority. A distribution plot is printed. With priorities, the higher the priority the better chance the thread has of being scheduled. This idea came from the script /usr/demo/dtrace/pri.d, which produces similar output for priority changes, not samples. Since this uses DTrace, only users with root privileges can run this command. EXAMPLES
This samples until Ctrl-C is hit. # priclass.d FIELDS
value process priority count number of samples of at least this priority SCHEDULING CLASSES
