parser_logger = logging.getLogger("CSHEL_parserlogger"); #logging.basicConfig() parser_logger.addHandler(RotatingFileHandler( "logfile", mode='a', maxBytes=7340032, backupCount=4, encoding=None, delay=False)) #d = { 'clientip' : '192.168.0.1', 'user' : 'fbloggs' } parser_logger.info('Protocol problem: %s', 'connection reset') 

This would create a file named logfile, but won't write anything into it. If I change the last line to

parser_logger.warning('Protocol problem: %s', 'connection reset') 

it would log the message into the "logfile" properly.

I am sure it's a petty thing that I am missing, but I am not able to figure out what it is.
