Hi, Is possible add HTTP response code (example: 200,400,500) to labels?

It is for counters. Spring actuator expose those as well, but not for gauge.
"counter.status.GET.200.prometheus": 4913
If this PR is accepter i will also create a converter for it. In order to make spring boot expose all those metrics you need to enable in the configuration like this:

endpoints:
  metrics:
    filter:
      gauge-submissions: per-http-method, merged
      counter-submissions: per-http-method, merged

This seems very fragile and depends on assumptions of metric naming that are not going to be true in general. I don't think this is something we can include out of the box, as it's going to be environment specific.

I did feel the same way once I wrote it, but it is environment specific just for spring boot. Without this converter the metrics becomes quite useless.

It's environment specific to what other metrics you have lying around, and which endpoints you have.

The spring boot metrics integration is only meant to be a stop gap until you can get instrumentation with the client library in place.

@hsdmiranda Spring has initial support to milti-dimensional metrics coming https://github.com/spring-projects/spring-metrics/blob/master/src/main/java/org/springframework/metrics/instrument/web/MetricsWebFilter.java

It has a few point releases, so you can pull it in via maven. It is pretty new, but coming together pretty quickly.

I agree that the current SpringbootMetricsCollector is really useless in its current form without your changes, I would even recommend we deprecate it.

I don't really agree with that. But I strongly agree with the fragile reason.

The same could be said about the Dropwizard integration. It's better than nothing, and gives you something to work from when starting out.

I agree that is better than nothing. But with the current solution for spring boot is just like nothing :)

I think the solution as proposed by @checketts will be a better one, once they release the multi-dimension metrics
