Python logging configuration file
提问by Scott
I seem to be having some issues while attempting to implement logging into my python project.
我在尝试登录我的 python 项目时似乎遇到了一些问题。
I'm simply attempting to mimic the following configuration:
我只是试图模仿以下配置：
Python Logging to Multiple Destinations
However instead of doing this inside of code, I'd like to have it in a configuration file.
但是，我不想在代码中执行此操作，而是希望将其放在配置文件中。
Below is my config file:
下面是我的配置文件：
[loggers]
keys=root
[logger_root]
handlers=screen,file
[formatters]
keys=simple,complex
[formatter_simple]
format=%(asctime)s - %(name)s - %(levelname)s - %(message)s
[formatter_complex]
format=%(asctime)s - %(name)s - %(levelname)s - %(module)s : %(lineno)d - %(message)s
[handlers]
keys=file,screen
[handler_file]
class=handlers.TimedRotatingFileHandler
interval=midnight
backupCount=5
formatter=complex
level=DEBUG
args=('logs/testSuite.log',)
[handler_screen]
class=StreamHandler
formatter=simple
level=INFO
args=(sys.stdout,)
The problem is that my screen output looks like:
2010-12-14 11:39:04,066 - root - WARNING - 3
2010-12-14 11:39:04,066 - root - ERROR - 4
2010-12-14 11:39:04,066 - root - CRITICAL - 5
问题是我的屏幕输出看起来像：
2010-12-14 11:39:04,066 - root - WARNING - 3
2010-12-14 11:39:04,066 - root - ERROR - 4
2010-12-14 11:39 :04,066 - 根 - 关键 - 5
My file is output, but looks the same as above (although with the extra information included). However the debug and info levels are not output to either.
我的文件是输出，但看起来和上面一样（虽然包含了额外的信息）。然而，调试和信息级别不会输出到任何一个。

Here is my simple example showing failure:
这是我显示失败的简单示例：
import os
import sys
import logging
import logging.config
sys.path.append(os.path.realpath("shared/"))
sys.path.append(os.path.realpath("tests/"))
class Main(object):
@staticmethod
def main():
logging.config.fileConfig("logging.conf")
logging.debug("1")
logging.info("2")
logging.warn("3")
logging.error("4")
logging.critical("5")
if __name__ == "__main__":
Main.main()

It looks like you've set the levels for your handlers, but not your logger. The logger's level filters every message before it can reach its handlers and the default is WARNINGand above (as you can see). Setting the root logger's level to NOTSETas you have, as well as setting it to DEBUG(or whatever is the lowest level you wish to log) should solve your issue.
看起来您已经为处理程序设置了级别，但没有为记录器设置级别。记录器的级别会在每条消息到达其处理程序之前对其进行过滤，默认值为WARNING及以上（如您所见）。将根记录器的级别设置NOTSET为您拥有的级别，并将其设置为DEBUG（或您希望记录的最低级别）应该可以解决您的问题。

Adding the following line to the root logger took care of my problem:
将以下行添加到根记录器解决了我的问题：
level=NOTSET

I think you should add the disable_existing_loggers to false.
我认为您应该将 disable_existing_loggers 添加到 false。

Just add log level in [logger_root]. It is worked.
只需在[logger_root]. 它起作用了。
[logger_root]
level=DEBUG
handlers=screen,file
