Micrometer "enable" annotations property does not cover observed aspect

[ggsurrel]

I am working on a large project with some AOP in it, and evaluating pointcuts can be a bit lenghty when starting the application. So I would like to get rid of the unused ones.

In order to do this, it would be nice to have a way to disable ObservedAspectConfiguration: the class is package protected so I cannot exclude it from the autoconfiguration, and there is no ConditionalOnProperty annotation on it either.

It looks like we missed the ObservedAspect when we took care of #39128. I think it's fair to assume that management.observations.annotations.enabled=false should do this already.

As a temporary solution, you can register your own BeanDefinitionRegistryPostProcessor to exclude ObservedAspect:

    @Bean
    static BeanDefinitionRegistryPostProcessor excludeObservedAspect() {
        return (registry) -> {
            if (registry.containsBeanDefinition("observedAspect")) {
                registry.removeBeanDefinition("observedAspect");
            }
        };
    }
