Python: Seting up logging.

I like the Python logging module, but for some reason I always have issues remembering how to set it up. This is my cheat sheet:

import logging
logger = logging.getLogger('App Name')
def SetupLogging():
logger.setLevel(logging.DEBUG)
#create console handler and set level to debug
ch = logging.StreamHandler()
ch.setLevel(logging.DEBUG)
#create formatter
# was:%(asctime)s - %(name)s - %(levelname)s: %(message)s"
formatter = logging.Formatter("%(levelname)s(%(name)s): %(message)s")
#add formatter to ch
ch.setFormatter(formatter)
#add ch to logger
logger.addHandler(ch)
logger.error("Whoops, an error!")
logger.debug ("Doing something boring")

The formatter options are:

%(name)s            Name of the logger (logging channel)
%(levelno)s Numeric logging level for the message (DEBUG, INFO,
WARNING, ERROR, CRITICAL)
%(levelname)s Text logging level for the message ("DEBUG", "INFO",
"WARNING", "ERROR", "CRITICAL")
%(pathname)s Full pathname of the source file where the logging
call was issued (if available)
%(filename)s Filename portion of pathname
%(module)s Module (name portion of filename)
%(lineno)d Source line number where the logging call was issued
(if available)
%(created)f Time when the LogRecord was created (time.time()
return value)
%(asctime)s Textual time when the LogRecord was created
%(msecs)d Millisecond portion of the creation time
%(relativeCreated)d Time in milliseconds when the LogRecord was created,
relative to the time the logging module was loaded
(typically at application startup time)
%(thread)d Thread ID (if available)
%(process)d Process ID (if available)
%(message)s The result of record.getMessage(), computed just as
the record is emitted
