Metrics always null about vertx-dropwizard-metrics

[vietj]

can you provide a reproducer please ?

[leolux]

Yep, I am working on it now.

[leolux]

Mhh, the issue seems not reproducable with the 3.0.0 Snapshot, but with the current up-to-date code. Is it possible that my code version is ahead of the snapshot version from https://oss.sonatype.org/content/repositories/snapshots?

[leolux]

I think that I've found the "cause": The metrics are null when pom.xml contains a dependency to vertx-web. I finish my reproducer now.

I'm not able to have null when I run it:

[leolux]

Ok, thank you. I don't know what happened to my project vertx-web. So I made a new git clone and now everything works. It seems that the command git pull -> Already-up-to-date was not enough in my case.

[BlackRider97]

I also have same problem. Whenever I call metricsService.getMetricsSnapshot(vertx) , it always returns null

• vertx-auth-common-3.2.0.jar
• vertx-core-3.2.0.jar
• vertx-dropwizard-metrics-3.2.0.jar
• metrics-core-3.0.2.jar
• vertx-web-3.2.0.jar
• vertx-auth-jwt-3.2.0.jar

[vietj]

it means that you haven't enabled metrics in VertxOptions

[BlackRider97]

@vietj No. I have enabled it.

        Vertx vertx = Vertx.vertx();
        VertxOptions options = new VertxOptions();
        options.setWarningExceptionTime(500);
        options.setMetricsOptions(new DropwizardMetricsOptions().setEnabled(true).addMonitoredHttpServerUri(new Match().setValue("/*").setType(MatchType.REGEX)));
        Vertx.vertx(options);
        DeploymentOptions verticleOptions = new DeploymentOptions().setInstances(1);
        vertx.deployVerticle(new HttpServer(), verticleOptions, res-> {
            if (res.succeeded()){
                System.out.println("Http Server verticle deployment completed with id " + res.result());
            } else{
                System.out.println("Deployment failed!");
            }
        });

metricsService.metricsNames() also returns empty string array []

[vietj]

can you pack this in a small project and make a reproducer ?

[dixiesraj]

I tried with version 3.3.3. I have this issue.
Both the metricsNames and metrics are null / empty.

I also observed the following,

When I print the VertxOptions before creating a clusteredVertx, I get the following

metrics=MetricsOptions{enabled=true, json=null},

After the vertx creation, I get the following from vertx.properties map

clusterManager:io.vertx.spi.cluster.hazelcast.HazelcastClusterManager@73545b80, metricsEnabled:false,

Which mean, the VertxOptions set is not honoured during vertx creation.

[tsegismont]

Can you provide a reproducer? Thanks

I solved this issue. Looks like OSGi Version of DropwizardOptions
requires a separate classloader.

Thanks.

[SankalpPatil09]

i am facing the same issue, sometimes it returns value, but some time it returns null always

  Vertx vertx = Vertx.vertx(new VertxOptions().setMetricsOptions(
    new DropwizardMetricsOptions().setEnabled(true)
  ));
  
  
  vertx.setPeriodic(5000L, (handler) -> {
    MetricsService metricsService = MetricsService.create(vertx);
    JsonObject metrics = metricsService.getMetricsSnapshot("vertx.pools");
    System.out.println("vertx metrics new pool" + metrics);
  });

[SankalpPatil09]

Found the issue, it was due to the order of import of compile 'io.vertx:vertx-dropwizard-metrics:4.3.3' . Changed the order of import to start of dependencies in gradle, seems to work now. Which is very strange. Somehow declaring the dependency at the end was affecting the dropwizard.

[vietj]

that sounds very weird

[SankalpPatil09]

yes weird, it was something to do these dependencies.
implementation "io.vertx:vertx-micrometer-metrics:$vertxVersion"
implementation "io.micrometer:micrometer-registry-prometheus:1.2.0"

maybe these dependencies were overwriting the drop-wizard settings.
