The global log level specifies which kinds of events are logged across all loggers. The default level for message output to the console is INFO (which also includes SEVERE and WARNING messages).
You configure global logging by editing the logging.properties file. The default logging.properties file is located in the same directory as the domain.xml file, typically domain-dir/config. You can choose a different file name by using the java.util.logging.config.file system property to specify a file name. For example:
The ConsoleHandler has a separate log level setting that limits the messages that are displayed. For example:
java.util.logging.ConsoleHandler.level = INFO java.util.logging.ConsoleHandler.formatter = com.sun.enterprise.server.logging.UniformLogFormatter
