3 * py_syscolors.d - trace Python function flow plus syscalls, in color.
4 * Written for the Python DTrace provider.
6 * $Id: py_syscolors.d 27 2007-09-13 09:26:01Z brendan $
8 * USAGE: py_syscolors.d { -p PID | -c cmd } # hit Ctrl-C to end
10 * This watches Python function entries and returns, and indents child
16 * DELTA(us) Elapsed time from previous line to this line
17 * FILE Filename of the Python program
18 * LINE Line number of filename
19 * TYPE Type of call (func/syscall)
20 * NAME Python function or syscall name
22 * Filename and function names are printed if available.
24 * WARNING: Watch the first column carefully, it prints the CPU-id. If it
25 * changes, then it is very likely that the output has been shuffled.
