3 * py_calltime.d - measure Python elapsed times for functions.
4 * Written for the Python DTrace provider.
6 * $Id: py_calltime.d 41 2007-09-17 02:20:10Z brendan $
8 * This traces Python activity from all programs running on the system with
9 * Python provider support.
11 * USAGE: py_calltime.d # hit Ctrl-C to end
14 * FILE Filename of the Python program
15 * TYPE Type of call (func/total)
17 * TOTAL Total elapsed time for calls (us)
19 * Filename and function names are printed if available.
