How to make Twisted use Python logging?

Question

I've got a project where I'm using Twisted for my web server. When exceptions occur (such as network errors), it's printing to the console.

I've already got logging through Python's built-in log module - is there any way to tell the reactor to use that instead?

What's the usual pattern for this?

Answer 1

Found it. It's actually quite easy:

from twisted.python import log observer = log.PythonLoggingObserver(loggerName='logname') observer.start() 

You just set loggerName to the same logger name that you're using in logging.getLogger().

Answer 2

You can use twisted.python.log. For example:

from twisted.python import log log.msg('Hello, world.')
