ListeningSocketHandler 0.1.0

ListeningSocketHandler
======================

The opposite of logging.handlers.SocketHandler

Example Usage
-------------

1. Create a logger

>>> import logging
>>> from ListeningSocketHandler import ListeningSocketHandler
>>> log = logging.getLogger()
>>> log.setLevel(logging.DEBUG)

2. Create some handlers

A normal StreamHandler that outputs to stderr and
a ListeningSocketHandler bound to port 12345.

>>> sh = logging.StreamHandler()
>>> sh.setLevel(logging.WARN)
>>> lh = ListeningSocketHandler(12345)
>>> lh.setLevel(logging.DEBUG)

3. Add handlers to the logger

>>> log.addHandler(sh)
>>> log.addHandler(lh)

4. Log some things

>>> log.info("An informational message")
>>> log.warn("A warning message")
A warning message

5. Connect to the logger, and log more detailed events

In a new shell, connect to the logger.

2. Add the ListeningSocketHandler to the LOGGING dict

LOGGING = {
...
'handlers': {
'listeningsocket': {
'level': 'DEBUG',
'class': 'ListeningSocketHandler.ListeningSocketHandler',
},
...
},
'loggers': {
'myapp': {
'handlers': ['listeningsocket'],
'level': 'DEBUG',
'propagate': True,
},
...
},
}

3. Run the server, and check the logs

Refresh the view, or perform the task to reproduce your bug, then break out
with Control-C when you've got the logs that you want.
