Disable the micrometer metrics which are enabled by default

[ShubhamRwt]

Hi,

I tried to disable the quarkus.micrometer.enabled which disables the micrometer metrics support completely and I was able to do that but then I got errors for MetricsReporter class and RestBridge class

Build failure: Build failed due to errors
        [error]: Build step io.quarkus.arc.deployment.ArcProcessor#validate threw an exception: javax.enterprise.inject.spi.DeploymentException: javax.enterprise.inject.UnsatisfiedResolutionException: Unsatisfied dependency for type io.micrometer.prometheus.PrometheusMeterRegistry and qualifiers [@Default]
        - java member: io.strimzi.kafka.bridge.quarkus.MetricsReporter#meterRegistry
        - declared on CLASS bean [types=[io.strimzi.kafka.bridge.quarkus.MetricsReporter, java.lang.Object], qualifiers=[@Default, @Any], target=io.strimzi.kafka.bridge.quarkus.MetricsReporter]

which I think are reasonable since I think that disabling the property removes the classes required

Is there some way I can disable the micrometer metrics or maybe a way to disable/ignore the endpoint /q/metrics?

Micrometer is not OTel.
Will evaluate your request.

Micrometer is not OTel.

Yeah I know that. I was just making the point about "fixing" (enabled/disabled) stuff at build time and not allowing doing at runtime. I think it's valid for any feature.

[ebullient]

you can disable publishing of any MeterRegistry which will make it a no-op.. But the enable/disable is specifically to avoid bytecode manipulation and build-time injection, etc..

[ebullient]

You don't need to use the prometheus meter registry. You can (as I've shown) make your own.

Use the micrometer extension alone, and provide your own Micrometer MeterRegistry that does what you need and provides its own endpoint, or try what I've suggested on another discussion thread to replace the default prometheus meter registry so you can alter the scrape behavior that the default metrics handler invokes.

@ebullient I am trying the way you suggested. I was confused at some step so left a comment there. Just saw that you have put a thumbs up there

@ebullient could you please share the link to example?
