Java Logging
The Java logging tool enables you to view Java logging messages for debugging purposes. By means of a filter mechanism you can adjust which messages you want to view. The tool can be used by system administrators for problem diagnosis and by software developers for detailed tracing. Java logging messages are produced by the standard java.util.logging class. For other logging options in XperienCentral, see Logs. For a complete documentation of Java logging see https://docs.oracle.com/javase/8/docs/api/java/util/logging/Logger.html (link to Oracle).
...
With this Java logging tool, you can choose the level at which the handlers should pass through logging messages. You can separately set the level for the ConsoleHandler and the FileHandler.
