Python logging.DEBUG level doesn't logging

Question

I have a problem with python's logging lib. With the code below I create a "logger":

logger = logging.getLogger()
def logger_init(level):
    try:
        syslog = SysLogHandler(address=LOG_DESTINATION)
    except Exception, ex:
        return
    formatter = logging.Formatter('%(module)s[%(process)d]: %(message)s')
    syslog.setFormatter(formatter)
    syslog.setLevel(level)
    logger.addHandler(syslog)

And I call it like:

logger.debug(SOME_STR_TO_BE_LOGGED)

OR like:

logger.error(SOME_STR_TO_BE_LOGGED)

And I initialize the logger with:

log_level = logging.ERROR
if options.DEBUG_LOG: ####  This comes from options parser and it is True.
    log_level = logging.DEBUG
logger_init(log_level)

The problem is that the error, and warn is working very well, but neither info nor debug methods prints anything to syslog.

I'm using syslog-ng and I designed my filter, that is it will accept every level from debug to emerg.

What is the problem here? Any ideas?

You also have to set the level of the logger, not only the handler.

Add this to your logger_init:

logger.setLevel(level)
