The solution is based on dballanc's snippet.

Can easily be combined with any of the SQL tracing solutions.

You might want to run a separate logging server and redirect your logs there. Please refer to the logging reference manual.

# 1. In settings.py add something like this:

import logging
logging.basicConfig(
    level=logging.NOTSET,
    format='%(asctime)s %(levelname)-8s %(message)s',
    datefmt='%m-%d %H:%M',
    #change as needed
    filename='/path/to/log/dir/my-log-file.log', 
    filemode='a'
)
logging.getLogger('').setLevel(logging.NOTSET)


# 2. In settings.py add '<myapp>.middleware.trace.TraceMiddleware' 
# to MIDDLEWARE_CLASSES.


# 3. Then in <myapp>/middleware create trace.py:

import logging, datetime

class TraceMiddleware(object):
    def process_request(self, request) :
        logging.info(
            "%s %s" % (request.META['REQUEST_METHOD'],
            request.get_full_path())
        )
        request.started = datetime.datetime.now()
        return None

    def process_response(self, request, response) :
        delta = (datetime.datetime.now() - request.started)
        logging.info(
            "<- Response in: %f sec.",
            delta.seconds + (delta.microseconds / 1000000.0)
        )
        return response

    def process_exception(self, request, exception):
        logging.exception("*** EXCEPTION ***")


# 4. Enjoy luxury of the logging API in your code:

    ....
    logging.debug('Redirecting to the home page')
    return HttpResponseRedirect('/')

request.started does not seem to exist in django, maybe it did sometime? That makes the middleware not very useful. Otherwise, good to know about the logging module

This saved me loads of time from having to concentrate while stepping though a deeply recursive method. I was able to easily see that I forgot to import the time module. ha!
