Expose metrics from Micrometer

[jonesbusy]

What feature do you want to see added?

Hi,

I'm interested by collecting Micrometer (https://micrometer.io/) metrics from a library (like outbound HTTP request or more high level metrics) packaged as a Jenkins plugin and expose them as prometheus metrics to the Jenkins controller (for usage purpose accross a farm of Jenkins controller). The plugin/library as only dependency on micrometer-core (basically without backend: https://github.com/jenkinsci/micrometer-core-api-plugin)

From what I understood this plugin already "convert" DropWizard (metrics-plugin) into Prometheus one

So I guess it must be possible to setup a PrometheusMeterRegistry when this plugin is installed (https://docs.micrometer.io/micrometer/reference/implementations/prometheus.html)

More info also on (https://quarkus.io/guides/telemetry-micrometer)

Any thought? It's still a bit fuzzy on how to integrate

Since Jenkins (afaik) uses dropwizard metrics and this plugin picks up these metrics and converts them to prometheus format it's probably the best to build a bridge between micrometer and Dropwizard (Quick Search found me https://github.com/micrometer-metrics/micrometer/blob/main/micrometer-core/src/main/java/io/micrometer/core/instrument/dropwizard/DropwizardMeterRegistry.java) But didn't dig any deeper yet

I see. Thanks for the pointer
