I wrote the below code

    log_config = (config.worker_log_config if use_worker_options else config.log_config)
    log_file = (config.worker_log_file if use_worker_options else config.log_file)
    log_format = '%(asctime)s    -    %(name)s    -    %(lineno)d    -    %(levelname)s    -    %(request)s    -    %(message)s'
    if (log_config is None):
        level = logging.INFO
        level_for_storage = logging.INFO
        if config.verbosity:
            level = logging.DEBUG
            if (config.verbosity > 1):
                level_for_storage = logging.DEBUG
        logger = logging.getLogger('')
        logger.setLevel(level)
        logging.getLogger('synapse.storage').setLevel(level_for_storage)
        formatter = logging.Formatter(log_format)
        if log_file:
            handler = logging.handlers.RotatingFileHandler(log_file, maxBytes=((1000 * 1000) * 100), backupCount=3)
            def sighup(signum, stack):
                logger.info('Closing    log    file    due    to    SIGHUP')
                handler.doRollover()
                logger.info('Opened    new    log    file    due    to    SIGHUP')
        else:
            handler = logging.StreamHandler()
        handler.setFormatter(formatter)
        handler.addFilter(LoggingContextFilter(request=''))
        logger.addHandler(handler)
    else:
        def load_log_config():
            with open(log_config, 'r') as f:
                logging.config.dictConfig(yaml.load(f))
        def sighup(signum, stack):
            logging.info('Reloading    log    config    from    %s    due    to    SIGHUP', log_config)
            load_log_config()
        load_log_config()
    if getattr(signal, 'SIGHUP'):
        signal.signal(signal.SIGHUP, sighup)
    observer = STDLibLogObserver()
    globalLogBeginner.beginLoggingTo([observer], redirectStandardIO=(not config.no_redirect_stdio))
