What is "logback"

Logback is considered "the successor to Log4j", one of the most popular log Apis in Java. It was designed by the same creator of Log4j, Ceki Gülcü, who drew on all the experience previously gained in relation to logging. The result was a faster and resource-consuming API compared to its predecessors, often with a considerable difference.

It has very useful features such as Markers, parameterized statements, stack tracing events and filters. More details and other resources can be found at documentation.
