Python traces Python using DTrace

October 19th, 2011 • Comments Off on Python traces Python using DTrace

Another example of how to use Python as a DTrace consumer. This little program traces a Python program while is runs and shows you the flow of the code. The output is displayed in a Treeview (An indent mean that python called another function – Stepping back means that the function returned) and when double clicking the source code is displayed (Would be nice to open pydev as well).

Another example of Python as a DTrace consumer: This small GUI gives an up to date view of the number of syscalls made by an executable. Since this GUI is a live up to date view you can watch the circles appear, grow and become smaller again 🙂

Now on to other things…maybe creating live animated callgraphs as your program runs? 😛
