Question

I’ve setup a logger using the following code

def setup_logging():
    import logging
    import logging.handlers
    import os
    #from time import gmtime, strftime
    #import logging.handlers

    logger = logging.getLogger('apt')
    logger.setLevel(logging.DEBUG)

    # create file handler
    fh = logging.handlers.RotatingFileHandler(os.path.join('..','logs','apt.log'), maxBytes=1000000, backupCount=5)
    fh.setLevel(logging.DEBUG)

    # create console handler
    ch = logging.StreamHandler()
    ch.setLevel(logging.DEBUG)

    # create formatter and add it to the handlers
    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
    ch.setFormatter(formatter)
    fh.setFormatter(formatter)

    # add the handlers to logger
    logger.addHandler(ch)
    logger.addHandler(fh)

The prints the log messages to both a file and the console (which is what I was after). The only issue is that the console message are red. This is distracting since red makes everything look like an error (when it just info). How can I change it so that the console messages are a different color?

Ideally, black for debug and info, red for warning and above.

I’m using Eclipse and PyDev.

The PyDev console highlights messages to stderr in red by default. Python’s logging.DEBUG will send messages to stderr. If you wish to change this behavior, see this post: Logging, StreamHandler and standard streams
