        LoggerContext lc = (LoggerContext) LoggerFactory.getILoggerFactory();
        GelfAppender gelfAppender = new GelfAppender();

        gelfAppender.setName("gelfudp");
        gelfAppender.setGraylogHost(host);
        gelfAppender.setGraylogPort(port);
        gelfAppender.setOriginHost("myKarmaZipkin");
        gelfAppender.setLevelIncluded(true);
        gelfAppender.setLocationIncluded(true);
        gelfAppender.setLoggerIncluded(true);
        gelfAppender.setMarkerIncluded(true);
        gelfAppender.setMdcIncluded(true);

        gelfAppender.addAdditionalField("environment=env");


        gelfAppender.setContext(lc);
        gelfAppender.start();

        Logger logger = (Logger) LoggerFactory.getLogger(GrayLogTest.class);
        logger.addAppender(gelfAppender);
        logger.setLevel(Level.DEBUG);
        logger.setAdditive(true);
