Use python's logging module and pythonlogging Module I. Starting from a use case To develop a log system, you must output logs to the console and write log files. Python code Import logging # Create a logger Logger = logging. getLogger ('mylogger ') Logger. setLevel (logging. DEBUG) # Create a handler for writing log files Fh = logging. FileHandler ('

Module-level functions Logging.getlogger ([name]): Returns a Logger object that returns root if no name is specified logger Logging.debug (), Logging.info (), logging.warning (), Logging.error (), logging.critical (): Set the log level for root logger Logging.basicconfig (): Establishes a streamhandler for the logging system with the default formatter, sets the

1. Go to the official Download log4j 2, import jar package, basically you only need to import the following two jar packages on it (xx is a messy version number): Log4j-core-xx.jar Log4j-api-xx.jar 2. Import into your project: This will not be said. 3. Start using: We know that to use the log4j log in a class, you only need to declare the following member variable (in fact not necessarily a member variable, just for convenience) Copy Code code as follows: private static

Monolog sends your logs to files, sockets, inboxes, databases and various Web services. Monolog sends your logs to files, to sockets, to mailboxes, to databases or to other networked storage services (clouds). Monolog can be saved to one or more storage media (later stack bubbling processing).

This article mainly from log4cxx level, layout, format, naming rules, filter several aspects introduced. First, log4cxx naming rulesLogger is identified by the name of a string class, and the logger name is case-sensitive and has an inherited relationship between the names, with the parent name as the prefix, and the dot number. For example: X.y is X.y.z's father. A root logger (root

Monolog follows the PSR3 interface specification and can easily be replaced with other log class libraries that follow the same specification. Monolog has a good extensibility, through the handler, formatter and processor these interfaces, can be a variety of Monolog class library extension and customization. Basic usage Monolog can be installed via GitHub or composer, and the following is the latest version to install using composer: Composer require Monolog/monologWhat if you don't know wha

handles for you. Node. js works in a different way.Provides static file services Undoubtedly, the provision of static file services is the core function of Apache. Different from Node. js, you need to configure the static file service in the application. Fortunately, this is very simple. it is well documented and implemented in Express.Logs Many basic Apache configurations provide you with access logs and error logs. When using Node. js, you may have guessed it. you also need to configure it in
