I tried but didn't log access records of tornado. Why?

What about configure filename in TimedRotatingFileHandler? In code i can add in end time or date in filename. For example: handler = handlers.TimedRotatingFileHandler('config.log'+datetime.datetime.now().strftime('%d-%m-%Y'), when='midnight')
How i can do this in config file?
