pidmon

pidmon is a collection of hacks to monitor running processes for activities, detecting when processes are created and destroyed and helping to wait for activity on a certain PID.

Inspired by discussion on http://stackoverflow.com/questions/6102535/

Examples

Exploring the process tree:

>>> p = pidmon.Process(1)
>>> p.name
'init'
>>> p.children
[...]

Waiting on processes:

>>> pidmon.waitpid(5) # doesn't need to be be a child process
>>> pidmon.waitpid(10001, recursive=True) # wait for process and any orphaned descendants

You can also catch processes that are started indirectly, e.g. through a factory:

>>> pidmon.waitpid(12345, graft_func=lambda p: p.name == 'gnome-terminal')
