public class test {
    private static final Logger log = Logger.getLogger(test.class);

    public static void main(String[] args) {
        Logger rootLogger = Logger.getRootLogger();

        rootLogger.setLevel(Level.DEBUG);

        PatternLayout layout = new PatternLayout("%t: %p: %m%n");
        SyslogAppender syslogAppender = new SyslogAppender(layout, "localhost",
                SyslogAppender.LOG_USER);
