logging getlogger

When logging with Python's logging module, I encountered the problem of duplicate logging, the first record was written once, the second record was written two times, and the third record was written three times. It's a headache, but it's not a diary. Online search for Causes and solutions:reason: No removal of handlerWorkaround: After

First, starting from a usage scenarioDevelop a log system that outputs logs to the console and to log filesPython code Import logging # Create a Logger Logger = Logging.getlogger (' MyLogger ') Logger.setlevel (logging. DEBUG) # Create a handler to write to the log file FH = logging. Filehandler (' Test.log ') Fh.setlevel (

first, Basic UsageOnly the basic configuration is required and can be used.import loggingdef fun2 (): logging.basicconfig (filename="fun2.log", format ="% (asctime) s% (message) s", level=logging. DEBUG) logging.debug ("This isfun2 log")second, the detailed configurationFirst add a Filehandler to configure the record of the file, formatter to set the format of the record and time format, GetLogger is

-grained settings for logs to be output.Formatters: set the final output format The following is an example of how to use these components. Import logginglogger = logging. getLogger ('logger _ name') # create a logger object. setLevel (logging. DEBUG) handler = logging. streamHandler () # create a console handler and s

Directory[TOC]First, the problem is thrownPython's logging module is a powerful tool for Python to print logs during use. We can use the logger, Handler, formatter of the logging module to encapsulate our logs, specifying the path, format, and location of the log output. When declaring logger, you can pass a string as a label for this logger. Always thought that this logger is a singleton object design patt

First introduce how to find out, the line of the project log is through the logging module to the Syslog, ran for a period of time to find the syslog UDP connection over 8W, yes 8 W. The main logging module is wrong. One of the requirements we had before is to output the current connection information for each connection log, so each connection creates a log instance, assigns a Formatter, and creates a log

memory leakage, let's take a look at the cause of memory leakage. First, let's look at the getLogger code: 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 Logger. manager. getLogger i
