Airbrake provides a service that aggregates errors from applications. This project is specifically designed for asynchronous Python Twisted code to send exceptions to an airbrake server. Unlike traditional synchronous Python code, there can be no blocking in the error reporting in a Twisted project. This library connects to the remote server in a non-blocking fashion.

easy_install txairbrake

# import the observer
from txairbrake.observers import AirbrakeLogObserver

# Create observer.  Params are api key, environment, and use SSL.  The last two are optional.
ab = AirbrakeLogObserver("mykey", "production", True)

# start observing errors
ab.start()

Airbrake costs money. If you don't want to spend money, consider using Errbit, which is free and can run for free on Heroku. If you do end up using an alternative server, the observer constructor takes a final parameter that is the hostname of your airbrake-compliant server.
