NAME
       runocc.d - run queue occupancy by CPU. Uses DTrace.

SYNOPSIS
       runocc.d

DESCRIPTION
       This  prints  the dispatcher run queue occupancy by CPU each second.  A
       consistant run queue occupancy is a sign of CPU saturation.

       The value is similar to that seen in "sar -q", however this  is	calcu‐
       lated in a more accurate manner - sampling at 1000 Hertz.

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

EXAMPLES
       Print %runocc by CPU every second,
	      # runocc.d

FIELDS
       CPU    cpu ID

       %runocc
	      percent run queue occupancy, sampled at 1000 Hertz

DOCUMENTATION
       See the DTraceToolkit for further documentation under the  Docs	direc‐
       tory. The DTraceToolkit docs may include full worked examples with ver‐
       bose descriptions explaining the output.

EXIT
       runocc.d will sample until Ctrl-C is hit.
