Are there any applications that wrap spring actuator metrics in some nice appealing form, instead of JSON? I would like to have nice view of all existing beans, to learn how spring actualy works.
Take a look at spring-boot-admin:
https://github.com/codecentric/spring-boot-admin
According to spring documentation, actuator can provide data to dropwizard metrics regestry. Dropwizard in its turn supports streaming metrics to Ganglia and Graphite backends.
Graphite can draw some charts but those look pretty plain. You can integrate it with graphana dashboard to achieve impressive visualisation.

I'm trying my first steps with Quarkus metrics, using SmallRye. I enabled it and it works when I call http://localhost:8080/api/metrics/application (my quarkus.http.non-application-root-path is api).
But although I see other SmallRye parts in the Dev UI (SmallRye Health, SmallRye OpenAPI), the SmallRye Metrics is inactive (gray, can't be clicked). Why is that? Am I missing some configuration?
Also, it would be great if the metrics showed up on the Swagger UI, since Swagger really shows everything that the service can do. It works great with SmallRye Health, but not with SmallRye Metrics. How can I achieve that?
I have a non boot spring application with micrometer integrated. Right now we are pushing these metrics to the logging file using LoggingRegistry.
We want to enhance this project to expose these metrics in the Rest API(we cannot use actuator as turning ON auto configuration is causing issues in our non boot application).Is there any way to expose these metrics which are automatically provided by the micrometer in the Rest API?
Any example will be appreciated?
You can add PrometheusMeterRegistry, it is for this use case, see the docs: https://micrometer.io/docs/registry/prometheus
The Exemplars support essentially adds the trace-id to metrics that are being scraped. I found a tutorial on how would it work with GoLang[1] but cannot figure out how to do this with spring boot libraries/functionalities. I know that Prometheus Java Client supports it as described at [2] but not sure how to get it to work with Springboot.

Update: Exemplars are supported by Micrometer and Spring Cloud Sleuth.
I'm not 100% sure I get your question right: I'm assuming you are talking about the /actuator/prometheus endpoint.
The support for metrics in Spring is provided by Micrometer that also supports Prometheus and Spring Boot "just" sets up an actuator endpoint for it.
So the real question is: does Micrometer support exemplars? Right now it does not and we haven't had anyone asking for it so far (this issue is a little bit connected). So if you want this feature, please open an issue(Enhancement request) on GitHub.
Update: I opened an issue for this: https://github.com/micrometer-metrics/micrometer/issues/2672, please feel free to +1 or chime-in.
Adding exemplars support in Micrometer is not the end of the story, we need to add support for Spring Cloud Sleuth too and solve a few other potential issues.
Until this is implemented, I guess your best bet is using the prometheus client.
I am trying to get Production metrics for my application. I am using Actuator on top of Spring Boot. Actuator exposes an endpoint for that "/metrics". I have Autowired CounterService class to get my own metrics data. I will be displaying the metrics data in one of our Application Management UI. The problem here is that I don't want all the default metrics data, as the Response JSON given back by the /metrics endpoint is kind off heavy for me to parse and most of the default metrics data are useless for me and give it to the UI. I have gone through the Spring Docs, I didn't get any help.
Appreciate your help on this!
Oh So I found a way to deal with the scenario. Actually Spring This GitHub Link pretty much solves my problem. Actuator Supports Reqex support to query for the data you need. So my url looks like this now : http://{{hostname}}/metrics/counter.*.count instead of this http://{{hostname}}/metrics/. Hope this helps.
Have you tried wrapping the response class from metrics, with a Custom class?
While reading the documentation for Spring XD I seen that it has a model for collecting metrics.
But when I looked into the code, I have seen that this is a custom implementation for Spring XD. None the less in the project dependencies there is codahale's metrics.
No it would be pretty useful to be able to add reporters (like the Graphite reporter which is also in the libs of Spring XD ) to the collected metrics.
But I wasn't able to find anything in the documentation on wether this is possible or how this should be done.
Does somebody have a hint how to do it, or if it is possible at the moment?
Thanks,
Christoph
Spring XD runtime components (XD admin, container and single-node JVMs) use Spring Boot internally. Spring Boot supports collection of codahale's metrics:
http://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-metrics.html#production-ready-code-hale-metrics
Since the codahale metrics jars are available in $XD_HOME/lib, all these metrics are already exposed at the Spring XD management endpoint.
By default management endpoint is enabled on XD admin. You can access them:
http://localhost:9393/management/metrics
For the container JVM, you can set the management port explicitly by setting XD_MGMT_PORT and access from '/management/metrics' endpoint.
You can refer to monitoring-management section in Spring XD wiki for more detail.
