Most of our company's applications use log4j to get the execution and debugging logs for development stages Review collected by and hosted on G2.com.

1) Easy to implement.

2) We have implemented in java.

3) Easy configuration

4) Great documentation available with lot of example code.

First and foremost: Consistent Logging.

We created the json logger for the Apache Kafka which internally uses the log4j interface as per the business requirements.

There are few implementation of json logger of log4j available in the open source but we had specific requirements. Review collected by and hosted on G2.com.

Its the best logging software you could ever get as a open source Review collected by and hosted on G2.com.

All my developed applications uses log4j as logger utility. All the automation workflows logs are streamed and store into database using JDBC appenders. It is useful to create an insight report of my application health status and errors so that the support team can review them easily by pulling the logging reports from the database.

Amazing tool for logging it solves all the logging requirements required. Review collected by and hosted on G2.com.

A common industry standard logging jar which can be used in all our applications. Classification of logs into various category helps debugging application in big way also in indexing in log analyzer tool. Review collected by and hosted on G2.com.

I would recommend to use apache log4j to use even in small projects. It would help you writting a code with cleaniness . You will be aware of what would cause the project to fail and what needs to log against it. With that you will understand how to represent the prblem to client. You can even ask your client to read the logs and see what is wrong and describe the actual problem. It will help you to save your time as well as your client.

It helps in solving problem more quickly than looking into the code base if I explain it technically. I am working on Retail product having multiple modules linked togather. Its a common practice to use logging to identify which part of module is broken So It can be looked straight away rather than just wondering where it comes from.

Benefit:

It saves time. Increases your effeciency to identify the problem quickly and resolve it. Review collected by and hosted on G2.com.

I stream those logs in kibana to debug errors. Review collected by and hosted on G2.com.

Its good for logging your java code on server side, one must give it a try Review collected by and hosted on G2.com.

Greatly helped in debugging GWT code errors of configuration and xml files inclusion. Review collected by and hosted on G2.com.

It has helped me extensively in the application debugging mainly on the production environment and keeping track of programming flow of better Development. Helps in mitigating the risk of unexpected flow of application. Review collected by and hosted on G2.com.

I have worked on an wizard applicaiton, where we have a lot pages and users needs to navigate through different flows. So with the log4j log info, I'll get what are flow the users are going frequently and what the less used flow. Based on which we update our application to give a better experience.
