Python logging configuration file

I seem to be having some issues while attempting to implement logging into my python project.

I'm simply attempting to mimic the following configuration:

However instead of doing this inside of code, I'd like to have it in a configuration file.

Below is my config file:

[loggers]
keys=root

[logger_root]
handlers=screen,file

[formatters]
keys=simple,complex

[formatter_simple]
format=%(asctime)s - %(name)s - %(levelname)s - %(message)s

[formatter_complex]
format=%(asctime)s - %(name)s - %(levelname)s - %(module)s : %(lineno)d - %(message)s

[handlers]
keys=file,screen

[handler_file]
class=handlers.TimedRotatingFileHandler
interval=midnight
backupCount=5
formatter=complex
level=DEBUG
args=('logs/testSuite.log',)

[handler_screen]
class=StreamHandler
formatter=simple
level=INFO
args=(sys.stdout,)

The problem is that my screen output looks like:
2010-12-14 11:39:04,066 - root - WARNING - 3
2010-12-14 11:39:04,066 - root - ERROR - 4
2010-12-14 11:39:04,066 - root - CRITICAL - 5

My file is output, but looks the same as above (although with the extra information included). However the debug and info levels are not output to either.

I am on Python 2.7

Here is my simple example showing failure:

import os
import sys
import logging
import logging.config

sys.path.append(os.path.realpath("shared/"))
sys.path.append(os.path.realpath("tests/"))

class Main(object):

  @staticmethod
  def main():
    logging.config.fileConfig("logging.conf")
    logging.debug("1")
    logging.info("2")
    logging.warn("3")
    logging.error("4")
    logging.critical("5")

if __name__ == "__main__":
  Main.main()

Solution

It looks like you've set the levels for your handlers, but not your logger. The logger's level filters every message before it can reach its handlers and the default is WARNING and above (as you can see). Setting the root logger's level to NOTSET as you have, as well as setting it to DEBUG (or whatever is the lowest level you wish to log) should solve your issue.
