How to log only one level to a FileHandler using python logging module.

[fuzzylollipop]

I want a FileHandler to only log a single level say for example
logging.INFO, and nothing else.
do I need to create a custom Handler for this or is this doable with
some magic that is not documeneted somewhere?

Try looking into logging.Filters:
http://docs.python.org/lib/node358.html

An example:

import logging

class InfoFilter(logging.Filter):
def filter(self, record):
return record.levelno == 20

if __name__ == "__main__":
logger = logging.getLogger()
hdlr = logging.FileHandler("blah.log")
hdlr.addFilter(InfoFilter())
logger.addHandler(hdlr)

logger.exception("ERROR WILL ROBINSON")
