Apache Log.Java based logging utility.It was originally written by Ceki Glc and is part of the Apache Logging Services project of the Apache Software Foundation.Log. 4j is one of several Java logging frameworks.Glc has since started the SLF4.J and Logback3 projects, with the intention of offering a successor to Log.The Apache Log. 4j team has created a successor to Log.Log. 4j 2 was developed with a focus on the problems of Log.Logback, and addresses issues which appeared in those frameworks.In addition, Log.Log. 4j 2 is not backwards compatible with 1.On August 5, 2. 01.Apache Logging Services Project Management Committee announced6 that Log.Log. 4j 1 are recommended to upgrade to Apache Log.Apache Log. 4j 2editApache Log.Log. 4j 1 which was released as GA version in July 2.The framework was rewritten from scratch and has been inspired by existing logging solutions, including Log.The main differences78 from Log.Improved reliability.Messages are not lost while reconfiguring the framework like in Log.Logback. Extensibility Log.Simplified configuration syntax.Support for xml, json, yaml and properties configurations.Improved Filters.Property lookup support for values defined in the configuration file, system properties, environment variables, the Thread.Context Map, and data present in the event.Support for multiple APIs Log.Log. 4j 2, Log. 4j 1.SLF4. J, Commons Logging and java.JUL APIs. Custom Log Levels.Java 8 style lambda support for lazy loggingMarkers.Support for user defined Message objectsGarbage free or low garbage in common configurations.Improved speed. One of the most recognized features of Log.Asynchronous Loggers.Log. LMAX Disruptor.The library reduces the need for kernel locking and increases the logging performance by a factor 1.For example, in the same environment Log.Logback and Log. 4j 1 just write lt 2,0.Log. 4j log levelseditThe following table defines the built in log levels and messages in Log.The left column lists the log level designation in Log.Level. Description.OFFThe highest possible rank and is intended to turn off logging.FATALSevere errors that cause premature termination.Expect these to be immediately visible on a status console.ERROROther runtime errors or unexpected conditions.Expect these to be immediately visible on a status console.WARNUse of deprecated APIs, poor use of API, almost errors, other runtime situations that are undesirable or unexpected, but not necessarily wrong.Expect these to be immediately visible on a status console.INFOInteresting runtime events startupshutdown.Expect these to be immediately visible on a console, so be conservative and keep to a minimum.DEBUGDetailed information on the flow through the system.Expect these to be written to logs only. Automated Press Release Software Free . Generally speaking, most lines logged by your application should be written as DEBUG.TRACEMost detailed information.Expect these to be written to logs only.Since version 1. 2.Custom log levelseditLog.A source code generator tool is provided to create Loggers that support custom log levels identically to the built in log levels.Custom log levels can either complement or replace the built in log levels.Log. 4j configurationeditLog.Java code. Configuration files can be written in XML, JSON, YAML, or properties file format.Within a configuration you can define three main components Loggers, Appenders and Layouts.Configuring logging via a file has the advantage that logging can be turned on or off without modifying the application that uses Log.The application can be allowed to run with logging off until theres a problem, for example, and then logging can be turned back on simply by modifying the configuration file.Loggers1. 4 are named log message destinations.They are the names that are known to the Java application.Each logger is independently configurable as to what level of logging FATAL, ERROR, etc.In early versions of Log.A Logger can send log messages to multiple Appenders.The actual outputs are done by Appenders.There are numerous Appenders available, with descriptive names, such as File.Appender, Rolling.File. Appender, Console.Appender, Socket.Appender, Syslog.Appender, and SMTPAppender.Log. 4j 2 added Appenders that write to Apache Flume, the Java Persistence API, Apache Kafka, No.SQL databases, Memory mapped files, Random Access files1.Zero. MQ endpoints.Multiple Appenders can be attached to any Logger, so its possible to log the same information to multiple outputs for example to a file locally and to a socket listener on another computer.Appenders use Layouts1.A popular way to format one line at a time log files is Pattern.Layout, which uses a pattern string, much like the C C function printf.There are also HTMLLayout and XMLLayout formatters for use when HTML or XML formats are more convenient, respectively.Log. 4j 2 added Layouts for CSV, Graylog Extended Log Format GELF,1.JSON, YAML and RFC 5.In Log. 4j 2, Filters2.Loggers and Appenders.In addition to filtering by log level and regular expression matching on the message string, Log.Markers or Thread Context Map and JSR 2.To debug a misbehaving configuration In Log.TRACE to send internal status logging output to standard out.To enable status logging before the configuration is found, use the Java VM property Dorg.Status. Logger. leveltrace.In Log. 4j 1, use the Java VM property Dlog.To find out where a log.Class. get. Resourcelog.There is also an implicit unconfigured or default configuration of Log.Log. 4j instrumented Java application which lacks any Log.This prints to stdout a warning that the program is unconfigured, and the URL to the Log.As well as printing this warning, an unconfigured Log.ERROR or FATAL log entries to standard out.Example for Log. 4j 2editlt UTF 8 lt Configurationstatustracemonitor.Interval6. 0 lt Properties lt Propertynamefilename targettest.Property lt Properties lt Appenders lt ConsolenameSTDOUT lt Pattern.Layoutpatternd p c1.Console lt Filenamefilefile.Namefilename lt Pattern.Layout lt pattern d p c1.Pattern.
