In this chapter, we looked at why logging is important to get a good and easy monitoring level. We also saw that a logging statement must be as minimally impactful on performance as possible so as not to defeat the optimization and coding you may have done elsewhere in your application.
This chapter gave you some common and simple patterns that can help you to rely, as much as possible, on the logging framework to make sure you maintain good performance.
Finally, we saw that several implementations may need to be configured in your applications, but that they will all share the same concepts, and that it is possible to rely on a single API, or even a single implementation from multiple APIs.
At this point of the book, you know what Java EE does and how to code and monitor an application. Now it is time to look at how you should approach a benchmark. This will be the topic...
