syscallbysysc.d

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

NAME

       syscallbysysc.d - syscalls by syscall. Uses DTrace.

SYNOPSIS

       syscallbysysc.d

DESCRIPTION

       syscallbysysc.d is a DTrace OneLiner to a report of the number of each type of system call made.

       This is useful to identify which system call is the most common.

       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 samples until Ctrl-C is hit.
	      # syscallbysysc.d

FIELDS

       first field
	      This is the system call type. Most have man pages in section 2.

       second field
	      This is the count, the number of occurrances for this system call.

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

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