Project description

Utility for inspecting python stack of running process (x64 linux only)


sudo pytb [pid]

will show you stacktrace of each python thread.

If you want to also see greenlet stacktraces, use

sudo pytb -g [pid]

this will also show you greenlets stacktraces. NOTE: in order to find all greenlets pytb looks for all gc tracked objects, so this may take a while if you have lots of objects.

Supports viewing python2 and python3 tracebacks (it will try to guess, whether it’s 2 or 3, however you can help it by specifying -2 or -3 option)

The utility works by reading /proc/<pid>/mem (this is why sudo is needed). It uses nm and objdump for finding inner python structures in memory.
