Are you trying to execute code when you receive a logline ?
If yes, give a look at the alarm subsystem:
http://uwsgi-docs.readthedocs.org/en/latest/AlarmSubsystem.html
you can pipe specific logs (matching the specified regexp) to a command,
a mule or directly rise a uWSGI signal.
Pay attention to what your alarms generate on stdout/stderr you could
easily generate loops (so avoid defining rules for .* or ^)
