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 calculated in a more accurate manner -sampling mannersampling
       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 directory. The DTraceToolkit docs may
       include full worked examples with verbose descriptions explaining the output.

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