Logback. In each case loggers are pre-configured to use console output with optional file output also available.By default, If you use the ‘Starters', Logback will be used for logging. Appropriate mongodb log level config Logback routing is also included to ensure that dependent libraries that jboss log level setting use Java Util Logging, Commons Logging, Log4J or SLF4J will all work correctly.TipThere are a lot of

logging frameworks available for Java. Don't worry if the above list seems confusing. Generally you won't need to change your logging dependencies and the Spring Boot defaults will http://guides.rubyonrails.org/debugging_rails_applications.html work just fine.26.1Log formatThe default log output from Spring Boot looks like this:2014-03-05 10:57:51.112 INFO 45469 --- [ main] org.apache.catalina.core.StandardEngine : Starting Servlet Engine: Apache Tomcat/7.0.52 2014-03-05 10:57:51.253 INFO 45469 --- [ost-startStop-1] o.a.c.c.C.[Tomcat].[localhost].[/] : Initializing Spring embedded WebApplicationContext 2014-03-05 10:57:51.253 INFO 45469 --- [ost-startStop-1] o.s.web.context.ContextLoader : Root WebApplicationContext: initialization completed in 1358 ms 2014-03-05 10:57:51.698 INFO 45469 http://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-logging.html --- [ost-startStop-1] o.s.b.c.e.ServletRegistrationBean : Mapping servlet: 'dispatcherServlet' to [/] 2014-03-05 10:57:51.702 INFO 45469 --- [ost-startStop-1] o.s.b.c.embedded.FilterRegistrationBean : Mapping filter: 'hiddenHttpMethodFilter' to: [/*]The following items are output:Date and Time -- Millisecond precision and easily sortable.Log Level -- ERROR, WARN, INFO, DEBUG or TRACE.Process ID.A --- separator to distinguish the start of actual log messages.Thread name -- Enclosed in square brackets (may be truncated for console output).Logger name -- This is usually the source class name (often abbreviated).The log message.NoteLogback does not have a FATAL level (it is mapped to ERROR)26.2Console outputThe default log configuration will echo messages to the console as they are written. By default ERROR, WARN and INFO level messages are logged. You can also enable a "debug" mode by starting your application with a --debug flag.$ java -jar myapp.jar --debugNoteyou can also specify debug=true in your application.properties.When the debug mode is enabled, a selection of core loggers (embedded container, Hibernate and Spring Boot) are configured to output more information. Enabling the debug mode does not configure your application to log all messages with DEBUG level.Alternatively,
that happen when some software runs. The software's developer adds logging calls to their code to indicate that certain events have occurred. An https://docs.python.org/3/howto/logging.html event is described by a descriptive message which can optionally contain variable data (i.e. data that is potentially different for each occurrence of the event). Events also have an importance which the developer ascribes to the event; the importance can also be called the level or severity. When to use logging¶ Logging provides a set of convenience functions log level for simple logging usage. These are debug(), info(), warning(), error() and critical(). To determine when to use logging, see the table below, which states, for each of a set of common tasks, the best tool to use for it. Task you want to perform The best tool for the task Display console output config log level for ordinary usage of a command line script or program print() Report events that occur during normal operation of a program (e.g. for status monitoring or fault investigation) logging.info() (or logging.debug() for very detailed output for diagnostic purposes) Issue a warning regarding a particular runtime event warnings.warn() in library code if the issue is avoidable and the client application should be modified to eliminate the warning logging.warning() if there is nothing the client application can do about the situation, but the event should still be noted Report an error regarding a particular runtime event Raise an exception Report suppression of an error without raising an exception (e.g. error handler in a long-running server process) logging.error(), logging.exception() or logging.critical() as appropriate for the specific error and application domain The logging functions are named after the level or severity of the events they are used to track. The standard levels and their applicability are described below (in increasing order of severity): Level When it's used DEBUG
