Class TestSplitLogger

java.lang.Object
org.jlab.logging.TestSplitLogger
public class TestSplitLogger extends Object
A simple class demonstrating how to use SplitLogger.

The SplitLogger class will send SEVERE and WARNING log messages to stderr, and all lower levels to stdout.

How to set the logging level:

A .properties file is necessary, which has the class name and desired log level; for example, 

org.jlab.logging.TestSplitLogger.level = FINE
From high to low, the levels are: SEVERE, WARNING, INFO, CONFIG, FINE, FINER, FINEST.

There are some example .properties files you can use with this class, like so: 

java \
  -Djava.util.logging.config.file=common-tools/clas-logging/src/main/resources/org/jlab/logging/TestSplitLogger.finest.properties \
  -cp ... \
  org.jlab.logging.TestSplitLogger
You may write your own .properties file, to control the logging level of all classes which use logging.
