Micrometer custom MeterFilter not registered when not declared with @Produces annotation

[baiglin]

Describe the bug

Hello,

While tryin to add a custom MeterFilter, I was able to do it following the guide, usin a CDI bean that produces MeterFiler beans.

@Singleton
public class CustomConfiguration {

    @Produces
    @Singleton
    public MeterFilter customMeterFilter() {
        return ...;
    }
}

However, annotating my class with Singleton to make it a bean did not work.

@Singleton
public class CustomMeterFilter implements MeterFilter {

}

I was expecting that no matter the way the bean is declared, it would work, maybe I miss something ?

Expected behavior

Any MeterFilter bean would be added to the injectable MeterRegistry produced by quarkus extension

Actual behavior

Only bean created with @produces annotation are added to the list of MeterFilter

Based on the description you have added I would say that can't happen.

However since we have seen a lot of weird things, could you attach a sample project that exhibits the problematic behavior?

[baiglin]

Yes I am currently creating one smaller than our multi-module project. Thanks

If you run in dev mode, was your CustomMeterFilter bean removed?

Here is a small reproducer with two filters supposed to filter tags, one is working, the other seems not. So it seems I am able to reproduce even with the small project which is good.

Great, thanks!
