pl_calltime.d - measure Perl elapsed times for subroutines. pl_calltime.d This traces Perl activity from all programs running on the system with Perl provider support. Filename and subroutine names are printed if available. Any Evolving - uses the DTrace Perl provider, which may change as additional features are introduced. Check Perl/Readme to see what version these scripts are based on.

TOTAL Total elapsed time for calls (us)

See the DTraceToolkit for further documentation under the Examples, Notes and Docs directories. The example files may be especially useful as they aim to demonstrate how to interpret the output. pl_calltime.d will run until Ctrl-C is hit. Brendan Gregg [CA, USA] dtrace(1M)
