Override log level (java.util.logging) with JVM-argument?

Question

Is it possible to override/set log level of java.util.logging.Logger by passing an JVM option on start of the application?

Answer 1

There are the following system properties available where you can configure log levels of loggers and initialisation logic.

• java.util.logging.manager
  • You can define your own LogManager
• java.util.logging.config.class
  • Custom logging configuration as a Class file
• java.util.logging.config.file
  • Custom logging configuration as configuration file

The LogManager documentation has more information on them available, http://docs.oracle.com/javase/6/docs/api/java/util/logging/LogManager.html
