python配置日志

logger_file = "%s%s.log" % (LogPath, Setting.box_id)
print "Will Log into %s"%logger_file
logger = logging.getLogger(name)        # 获取或初始化logger,不传name,name就是设置的root,默认logging.info/error就是
logger.setLevel(logging.DEBUG)
logger_handler = RotatingFileHandler(filename=logger_file, maxBytes=1024 * 1024 * 100, backupCount=10)
logger_format = logging.Formatter(fmt='[%(asctime)s]-[%(filename)s:%(lineno)s:%(funcName)s]= %(message)s =!',
                                  datefmt='%Y.%m.%d %H:%M:%S')
logger_handler.setFormatter(logger_format)
logger.addHandler(logger_handler)

默认logger是root

root = RootLogger(WARNING)

def getLogger(name=None):
    """
    Return a logger with the specified name, creating it if necessary.

    If no name is specified, return the root logger.
    """
    if name:
        return Logger.manager.getLogger(name)
    else:
        return root

默认直接logging.info/error/debug 也是使用的root

logging.info()

def info(msg, *args, **kwargs):
    """
    Log a message with severity 'INFO' on the root logger.
    """
    if len(root.handlers) == 0:
        basicConfig()
    root.info(msg, *args, **kwargs)
