Before this can be used, please ssh into the robot with the username "admin". Go to /home/lvuser/ and run the commands:

mkdir logs; chmod 777 logs

So basically, to log you need to add these lines to your class.

make this variable: private Logger logger = Logger.getLogger("SomeNameHere");

add this to the constructor: logger.addHandler(Config.logFileHandler);

to see how its used, here's the javadoc: https://docs.oracle.com/javase/7/docs/api/java/util/logging/Logger.html

the logs are stored on the roboRIO at /home/lvuser/logs/
