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

NAME

       loads.d - print load averages. Uses DTrace.

SYNOPSIS

       loads.d

DESCRIPTION

       These are the same load averages that the "uptime" command prints.  The purpose of this script is to demonstrate fetching these values from
       the DTrace language.

       The first field is the 1 minute average, the second is the 5 minute, and the third is the 15 minute average. The value represents the aver-
       age number of runnable threads in the system, a value higher than your CPU (core/hwthread) count may be a sign of CPU saturation.

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

EXAMPLES

       Print load averages,
	      # loads.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.

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
	      The DTrace probe name for the event

       remaining fields
	      These contains the argument listing for the new process

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

       newproc.d will run forever until Ctrl-C is hit.
