Here's the confusion.  Each log named __name__ is under the root logger. 
  If you want them all, then catch them all with the root logger.

In, change getLogger(__name__) to getLogger('').  Only the 
included modules need __name__.  Or use two - one logger for setting 
handlers based on the root logger, and another based on __name__ for 
logging from the top level.
