Python记录器，打印没有父名称的子记录器％(name) [英] Python logger, print child logger %(name) without parent name

问题描述

我正在尝试使用Python记录日志.

I am trying Python logging.

由于我希望某些记录器共享一个格式化程序，因此我使用如下所示的日志记录层次结构.

Since I want some logger to share a formatter, I use hierarchy of logging like the below code.

如您所见，格式为'%(asctime)s - %(name)s - %(message)s'

这时，我希望记录器打印不带父名称的%(name)s部分.

At this point, I want loggers to print the %(name)s part without the parent name.

我的意思是，通常它将名称打印为'SYS.Start Up Routine'，但我想要'Start Up Routine'

I mean, normally it will print the name as 'SYS.Start Up Routine' but I want 'Start Up Routine'

有什么办法吗?

logging.root.level = logging.DEBUG
logger = logging.getLogger('SYS')
logger.setLevel(logging.DEBUG)

formatter = logging.Formatter('%(asctime)s - %(name)s - %(message)s')

streamHandler = logging.StreamHandler()
streamHandler.setFormatter(formatter)
logger.addHandler(streamHandler)

logger1 = logging.getLogger("SYS.Start Up Routine")
logger2 = logging.getLogger("SYS.Message Layer")
logger3 = logging.getLogger("SYS.Application Layer")

推荐答案

如果您想要名称说"bar"而不是"foo.bar"，只需登录到名为"bar"的记录器，然后将处理程序添加到根记录器.

If you want the name to say 'bar' instead of 'foo.bar', just log to a logger named 'bar', and add your handlers to the root logger.
