Currently, i have 2 custom spring artefacts- metrics-util and web-utils. metrics-util contains all the functions related to measuring the metrics such as a web-filter to calculate the metrics of all rest controller. Web-utils uses some functions from metrics-util to measure the metrics inside the function.

My main spring program calls web-utils functions within it. And i am using same name with different tags. The issue i am facing is i can see the metrics and the different tags at /actuator/metrics/{metric_name} but only the first instance of metric name is being displayed at the endpoint where Prometheus scrapes.

Micrometer version:

implementation 'io.micrometer:micrometer-core:1.12.3'
implementation 'io.micrometer:micrometer-registry-prometheus:1.12.3'

My config for registry:

@Configuration
@ComponentScan(basePackages = ["co.hyperface.ark.metricsutil.*"])
class BaseMetricsConfig {

    @Bean
    MeterRegistry meterRegistry() {
        return new PrometheusMeterRegistry(PrometheusConfig.DEFAULT)
    }
}

How im injecting in my program:

class MetricsUtil {

    private MeterRegistry meterRegistry

    @Autowired
    MetricsUtil (MeterRegistry meterRegistry) {
        this.meterRegistry = meterRegistry
    }
}

Expected result:

For any endpoint, web-filter gets activated first so its callcount{call_type='rest_controller'} must increase then since im calling web-utils function inside that controller, the calls callcount{call_type='external'} must be increased.

But at the scraping endpoint im getting only callcount{call_type='rest_controller'} . but im able to see both of them at /actuator/metrics/callcount
