The available logging levels in Logback are:

OFF (output no logs)

ERROR

LOGGER.trace("doStuff needed more information - {}", value);

LOGGER.debug("doStuff needed to debug - {}", value);

LOGGER.info("doStuff took input - {}", value);

LOGGER.warn("doStuff needed to warn - {}", value);

LOGGER.error("doStuff encountered an error with value - {}", value);

To disable dublicating log code to log, add to logback.xml:

private static final Logger log = LoggerFactory.getLogger(YourClassName.class);
