This course is intended for anyone who wants to understand the key functionality of the Log4j logging framework.

Log4j Training Course Overview

Log4j is an open-source logging software that returns log messages related to user-written code. It supports many output appenders per logger, custom-level logs in configuration, and configures logging behaviour at runtime with a configuration file. Logs are used to gather and store significant data so that it may be analysed at any time. It is beneficial for quick debugging, problem diagnosing, easy maintenance, and saving time and cost. This training helps learners to manage standalone applications for improving response time performance and supporting methods for multiple outputs. Gaining Log4j abilities and extensive knowledge will undoubtedly help individuals get higher designations at multinational corporations and climb the ladder of success.

In this 2-day Log4j Training course, delegates will gain a deep understanding of the Log4j framework and its logging process. During this training, delegates will learn about web applications that clean up resources when undeployed and JSPs that call their methods to log events. They will also learn about an Asynchronous Logger that improves application performance by executing input and output operations in real-time. Our highly experienced trainer will deliver this training course, who will put in their best efforts to make delegates understand things easily.

Course Objectives:

  • To set runtime behaviour using a configuration file and support output Appenders
  • To supply the adapter components needed to create a logging implementation
  • To learn about formatting, filtering, and error handling in Log4j
  • To gain an in-depth knowledge of the architecture of Log4j
  • To lower the garbage for web applications during steady-state logging
  • To understand the setup, configuration, and advanced features of Log4j

At the end of this training, delegates will be able to enhance throughput and have orders of magnitude lower latency than Log4j using Asynchronous Loggers. They will also be able to support interesting and complex constructs using messages to pass through logging systems efficiently.

Log4j Training FAQs


Log4j is an open-source logging software that returns log messages related to user-written code. It is a java-based logging system that is reliable, flexible, and fast, as well as an open-source logging API for java.
There are no formal prerequisites for attending this Log4j Training course. However, the basic understanding of Java.
This course is intended for anyone who wants to understand the key functionality of the Log4j logging framework.
Log4j is thread-safe, optimised for speed, based on a named logger hierarchy, supports multiple output Appenders per logger, handles Java exceptions, and alters implementations of the Appender interface.
Log4j is used to enable logging so that problems can be located, log at runtime without modifying the application binary, and output log statements to various output targets.
Logging is a valuable tool for understanding and debugging software runtime behaviour. Logs are used to gather and store crucial data and make it accessible for analysis at any time.
In this Log4j Training course, you will learn about architecture, API, configuration, web applications, JSPs, lookups, appenders, layouts, filters, async Loggers, garbage-free Logging JMX, plugins, and other essential topics related to logging or tracing API.
