Publish Spring MVC Metrics To Multiple Monitoring System Simultaneously Using Micrometer

Question

I have a use case wherein I want to publish my spring boot API metrics to Datadog & CloudWatch simultaneously.

I have added the below dependencies to my pom.

<dependency>
  <groupId>io.micrometer</groupId>
  <artifactId>micrometer-registry-statsd</artifactId>
  <version>${micrometer.version}</version>
</dependency>

<dependency>
  <groupId>io.micrometer</groupId>
  <artifactId>micrometer-registry-cloudwatch</artifactId>
  <version>${micrometer.version}</version>
</dependency>

Main Application class

@SpringBootApplication
public class MyApplication {
    @Bean
    MeterRegistryCustomizer<MeterRegistry> metricsCommonTags() {
      return registry -> registry.config().commonTags("my-tag", "my-common-tag");
    }
}

I have added all required properties in the application. properties as well.

I can see metrics are being published to both Datadog & CloudWatch with default metrics name http.server.request But I want the metrics name for Datadog to be different & for this, I have added the below property.

management.metrics.web.server.requests-metric-name = i.want.to.be.different

But this is changing the name for both CloudWatch & Datadog.

My question is, how can I change the default metrics name for Datadog only or keep words different for both.

Answer 1

Micrometer uses MeterFilters registered with a MeterRegistry to modified the meters that are registered. The modifications include the ability to map a meter's ID to something different.

In Spring Boot, you can use a MeterRegistryCustomizer bean to add a MeterFilter to a registry. You can use generics to work with a registry of a specific type, for example MeterRegistryCustomizer<DatadogMeterRegistry> for a customizer that is only interested in customizing the Datadog registry.

Putting this together, you can map the ID of the http.server.request meter to i.want.to.be.different using the following bean:

@Bean
MeterRegistryCustomizer<DatadogMeterRegistry> datadogMeterIdCustomizer() {
    return (registry) -> registry.config().meterFilter(new MeterFilter() {

        @Override
        public Id map(Id id) {
            if ("http.server.request".equals(id.getName())) {
                return id.withName("i.want.to.be.different");
            }
            return id;
        }

    });
}
