syscallbyproc.d - syscalls by process name. Uses DTrace.
syscallbyproc.d is a DTrace OneLiner to a report of the number of system calls made by process name.
This is useful to identify which process is causing the most system calls.
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.
See the DTraceToolkit for further documentation under the Docs directory. The DTraceToolkit docs may include full worked examples with verbose descriptions explaining the output.
syscallbyproc.d will sample until Ctrl-C is hit.
