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

NAME

       sigdist.d - signal distribution by process. Uses DTrace.

SYNOPSIS

       sigdist.d

DESCRIPTION

       This  is  a  simple DTrace script that prints the number of signals recieved by process and signal number. This script is also available as
       /usr/demo/dtrace/sig.d, where it originates.

       Since this uses DTrace, only users with root privileges can run this command.

EXAMPLES

       This samples until Ctrl-C is hit.
	      # sigdist.d

FIELDS

       SENDER process name of sender

       RECIPIENT
	      process name of target

       SIG    signal number, see signal(3head)

       COUNT  number of signals sent

BASED ON

       /usr/demo/dtrace/sig.d

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

       /usr/demo/dtrace/profpri.d
