3 * py_calldist.d - measure Python elapsed times for functions.
4 * Written for the Python DTrace provider.

8 * This traces Python activity from all programs running on the system with
9 * Python provider support.
11 * USAGE: py_calldist.d # hit Ctrl-C to end
13 * This script prints distribution plots of elapsed time for Python
14 * operations. Use py_calltime.d for summary reports.
17 * 1 Filename of the Python program
18 * 2 Type of call (func)
21 * Filename and function names are printed if available.
