Hi Benny, Log4j is a brilliant logging API available both on Java and .net framework. It is Reliable, Fast and Flexible logging framework written in Java. Some of the advantages of Log4j are:

  • Good logging infrastructure without putting in any efforts.

  • Ability to categorize logs at different levels (Trace, Debug, Info, Warn, Error and Fatal).

  • Direct logs to different outputs. For e.g. to a file, Console or a Database.

  • Lets you define the format of output logs.

  • Write Asynchronous logs which helps to increase the performance of the application.

  • Loggers in Log4j follow a class hierarchy which may come handy to your applications.
