NAME

       dispqlen.d - dispatcher queue length by CPU. Uses DTrace.

SYNOPSIS

       dispqlen.d

DESCRIPTION

       The  dispatcher	queue  length  is  an  indication  of CPU saturation.  It is not an indicatior of utilisation - the CPUs may or may not be
       utilised when the dispatcher queue reports a length of zero.

       This script measures this activity by sampling at 1000 Hertz per CPU.

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

EXAMPLES

       Print dispatcher queue length by CPU.
	      # dispqlen.d

DOCUMENTATION

       See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with ver-
       bose descriptions explaining the output.

EXIT

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

NAME

       newproc.d - snoop new processes. Uses DTrace.

SYNOPSIS

       newproc.d

DESCRIPTION

       newproc.d is a DTrace OneLiner to snoop new processes as they are run.  The argument listing is printed.

       This is useful to identify short lived processes that are usually difficult to spot using traditional tools.

       Docs/oneliners.txt and Docs/Examples/oneliners_examples.txt in the DTraceToolkit contain this as a oneliner that can be cut-n-paste to run.

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

EXAMPLES

       This prints new processes until Ctrl-C is hit.
	      # newproc.d

FIELDS

       CPU    The CPU that recieved the event

       ID     A DTrace probe ID for the event

       FUNCTION:NAME

       remaining fields

DOCUMENTATION
