Questions tagged [logback]

Modern logging facility for Java-based programs with many new features when compared to Log4J and java.util.logging.

Logback is intended as a successor to the popular log4j project. It was designed by Ceki Gülcü, log4j's founder. It builds upon a decade of experience gained in designing industrial-strength logging systems. The resulting product logback is faster and has a smaller footprint than all existing logging systems, sometimes by a wide margin. Logback also offers unique and rather useful features such as Markers, parameterized logging statements, conditional stack tracing and powerful event filtering. These are only a few examples of the useful features logback has to offer.

For its own error reporting, Logback relies on Status objects, which greatly facilitate troubleshooting. You may wish to rely on Status objects in contexts other than logging. Logback-core bundles Joran, a powerful and generic configuration system, which can be put to use in your own projects to great effect.

By default, the Logback encoder uses a date format similar to the ISO 8601 standard. But it lacks the "T" in the middle between the date and time portions. The T makes for easier parsing, and is required by the standard (unless private parties agree…
