the class Dashboard method start.

@Override
public void start() {
    MetricsService service = MetricsService.create(vertx);
    Router router = Router.router(vertx);

    HttpServer httpServer = vertx.createHttpServer();
    httpServer.requestHandler(router::accept).listen(8080);
    // Send a metrics events every second
    vertx.setPeriodic(1000, t -> {
        JsonObject metrics = service.getMetricsSnapshot(vertx.eventBus());
