* py_flowtime.d - snoop Python functions with flow and delta times.
|
|
* Written for the Python DTrace provider.

|
|
* This traces shell activity from Python programs on the system that are
|
|
* running with Python provider support.
|
|
*
|
|
* USAGE: py_flowtime.d # hit Ctrl-C to end
|
|
*
|
|
* This watches Python function entries and returns, and indents child
|
|
* function calls.
|
|
*
|
|
* FIELDS:
|
|
* C CPU-id
|
|
* TIME(us) Time since boot, us
|
|
* FILE Filename that this function belongs to
|
|
* DELTA(us) Elapsed time from previous line to this line
|
|
* FUNC Python function name
|
|
*
|
|
* LEGEND:
|
|
* -> function entry
|
|
* <- function return
|
|
*
|
|
* Filename and function names are printed if available.
|
|
*
|
|
* WARNING: Watch the first column carefully, it prints the CPU-id. If it
|
|
* changes, then it is very likely that the output has been shuffled.
