runocc.d(1) USER COMMANDS runocc.d(1)
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.
