Apache log4j Reviews & Product Details

It's really helpful if I am able to get logging event along with parameters while messages are logged. I also like the adaptor facility while using it along with other logging service. Review collected by and hosted on G2.com.

I felt just hiding such a big security vulnerability is a big crime. About 60% of all java applications around the world uses log4j indirectly. There might be lot of financial applications using it. That is biggest risk at high stakes. Review collected by and hosted on G2.com.

Can enable logging levels for specific packages, classes, which is very useful when we want to debug a particular package/class in production rather than allow the whole module. log level is amazing, which helps lot for application trouble shoot and debug them. printing class name and line is very helpful to identify and trouble shoot the issues. printing time is also gives benifits much and no need to set it explicitly. log4j feels me an extra enargy and which buld me on confidence on the system. Finaly Log4j features helped me lot for identify and sort out the production issue. Without log4j I may lost my job, Review collected by and hosted on G2.com.

When configuring the different appenders, we have to do the same configuration stuff multiple times, like date pattern and Threshold, which reduces the readability—expecting a common way to configure those. If there are lot of configuration like multiple appenders, complexity will be get increased. Review collected by and hosted on G2.com.

It's hard to pick one attribute which is better than others, but I far as I have experienced, it provides control over a class to limit what we want, from setting up the timestamp to print the stack trace of error occurred it hold you back and give far better experience than regular console log, moreover its safe and secure and can be used in production code and helps us debug any issue or check the performance of our application in a safe and descriptive way. Also it's gives us so many custom options to create the root file either using xml tags or a .properties file and cutomize the logs like timestamp design, method name, classname, line number and also file size limit wchi helps in tracing latest report and more over.

its nothing to dislike about log4j as it makes life easier for developer and apps to control your apps and store its behavior without fear of losing data. Its only disadvantage whcich i feel is the incorrect usage which can lead to failure in any method of improper logging will be difficult to trace and debug the issue in the application Review collected by and hosted on G2.com.

It shortens the number of lines of code. Cuts down the boilerplate code. Syntax I used in my Java applications, was far easy to remember. I think the team who created it has done a wonderful job. Review collected by and hosted on G2.com.
