1.1. When to use logging Logging库为简单的logging提供了一组方便的函数,其中包括debug(),info(),warning(),error()和critical()。下表说明了何时使用什么函数来logging: logging函数是根据他们的level命名的,具体描述如下: 1.2. A simple example import logging logging.warning('Watchout!') # will be displ...
import logging logging.warning('Watch out!') # will print a message to the console logging.info('I told you so') # will not print anything 如果你在命令行中输入这些代码并运行,你将会看到:WARNING:root:Watch out! 输出到命令行。INFO 消息并没有出现,因为默认级别是 WARNING 。打印的信息包含事件...
Theloggingmodule has adefault levelofWARNING, which is a level aboveDEBUG. Since we’re going to use theloggingmodule for debugging in this example, we need to modify the configuration so that the level oflogging.DEBUGwill return information to the console for us. We can do that by adding ...
logging.basicConfig(level=http://logging.INFO) 这段代码主要是用来配置日志的输出的,代码会将level以上级别日志输出,比如设置 level=logging.ERROR. 稍微总结一下就是:程序在运行的过程中会记录下大于或等于这个日志级别的日志信息,如果不设置level的值则打印大于等于 WARNING 级别的日志。
这里使用的是Python自带的logging模块或loguru模块(封装了logging模块)进行es的日志写入。 使用如下的方法进行包安装(建议使用es的版本为8以下,以防出现找不到包的错误): pip3 install"elasticsearch==7.9.1"-ihttps://pypi.tuna.tsinghua.edu.cn/simple ...
python logging加时间戳,一、StreamHandler流handler——包含在logging模块中的三个handler之一。能够将日志信息输出到sys.stdout,sys.stderr或者类文件对象(更确切点,就是能够支持write()和flush()方法的对象)。只有一个参数:classlogging.StreamHandler(stream=None)
The module needs two lines to set up logging, and then use the named logger: import logging log = logging.getLogger(__name__) def do_something(): log.debug("Doing something!") That is all there is to it. In Python, __name__ contains the full name of the current module, so this...
def__init__(self,name,other_attr=None,**kwargs):logging.Handler.__init__(self)print('初始化自定义日志处理器:',name)print('其它属性值:',other_attr)defemit(self,record):""" emit函数为自定义handler类时必重写的函数,这里可以根据需要对日志消息做一些处理,比如发送日志到服务器发出记录(Emit a...
The root logger is the default logger in the Pythonloggingmodule. While it can be tempting to use the root logger to simplify logging code, there are several reasons why it should be avoided: Lack of control: When you use the root logger, you have limited control over how log messages ar...
