.TH pridist.d 1m "Jun 13, 2005" "version 0.90" "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 users with root privileges can run this command. .SH EXAMPLES .TP This samples until Ctrl\-C is hit. # .B pridist.d .PP .SH FIELDS .TP CMD process name .TP PID process ID .TP value process priority .TP count number of samples of at least this priority .PP .SH BASED ON /usr/demo/dtrace/profpri.d .PP .SH DOCUMENTATION DTrace Guide "profile Provider" chapter (docs.sun.com) See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output. .SH EXIT pridist.d will sample until Ctrl\-C is hit. .SH SEE ALSO dispadmin(1M), dtrace(1M)
