How to suppress noisy factory started / stopped log messages from Twisted?

Question

I use twisted.web.client.Agent, which in turn uses HTTP11ClientProtocol. Countless factory start / stop messages hide messages that really interest me. Therefore, I am looking for a way to suppress them. Whether there is a?

This ( Twisted start / stopping factory / protocol less noisy log messages ) is a similar question, but since HTTP11ClientProtocol is not what I am creating, I cannot figure out where I would set the property to noisy to false.

Answer 1

If you want every _HTTP11ClientFactory in the application to disguise itself, you can simply set the noisy property at the class level:

 from twisted.web import client client._HTTP11ClientFactory.noisy = False 

A more flexible approach would be to create a custom HTTPConnectionPool that uses quiet factories and passes it to your Agent when you need a quieter log:

 from twisted.web import client class QuietHTTP11ClientFactory(client._HTTP11ClientFactory): noisy = False myQuietPool = client.HTTPConnectionPool(reactor) myQuietPool._factory = QuietHTTP11ClientFactory agent = client.Agent(reactor, pool=myQuietPool) 

Answer 2

I was able to do this only at the logging level:

 import logging logging.getLogger('twisted').setLevel(logging.CRITICAL)
