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 particular PID. Since this uses DTrace, only users with root privileges 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
