Vertx vertx = Vertx.vertx(new VertxOptions().setMetricsOptions(
  new MicrometerMetricsOptions()
    .setPrometheusOptions(new VertxPrometheusOptions().setEnabled(true))
    .setServerRequestTagsProvider(req -> {
      String uri = req.uri();
      return Collections.singletonList(Tag.of("path", uri));
    })
    .setClientRequestTagsProvider(req -> {
      String uri = req.uri();
      return Collections.singletonList(Tag.of("path", uri));
    })
    .setEnabled(true)));
