Getting started

Spring Boot auto-configures a composite MeterRegistry and adds a registry to the composite for each of the supported implementations that it finds on the classpath. Having a dependency on micrometer-registry-{system} in your runtime classpath is enough for Spring Boot to configure the registry.

Most registries share common features. For instance, you can disable a particular registry even if the Micrometer registry implementation is on the classpath. The following example disables Datadog:

Properties
YAML

management.datadog.metrics.export.enabled=false

management:
  datadog:
    metrics:
      export:
        enabled: false

You can also disable all registries unless stated otherwise by the registry-specific property, as the following example shows:

Properties
YAML

management.defaults.metrics.export.enabled=false

management:
  defaults:
    metrics:
      export:
        enabled: false

Spring Boot also adds any auto-configured registries to the global static composite registry on the Metrics class, unless you explicitly tell it not to:

Properties
YAML

management.metrics.use-global-registry=false

management:
  metrics:
    use-global-registry: false

You can register any number of MeterRegistryCustomizer beans to further configure the registry, such as applying common tags, before any meters are registered with the registry:

Java
Kotlin

import io.micrometer.core.instrument.MeterRegistry;

import org.springframework.boot.actuate.autoconfigure.metrics.MeterRegistryCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration(proxyBeanMethods = false)
public class MyMeterRegistryConfiguration {

	@Bean
	public MeterRegistryCustomizer<MeterRegistry> metricsCommonTags() {
		return (registry) -> registry.config().commonTags("region", "us-east-1");
	}

}

import io.micrometer.core.instrument.MeterRegistry
import org.springframework.boot.actuate.autoconfigure.metrics.MeterRegistryCustomizer
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration

@Configuration(proxyBeanMethods = false)
class MyMeterRegistryConfiguration {

	@Bean
	fun metricsCommonTags(): MeterRegistryCustomizer<MeterRegistry> {
		return MeterRegistryCustomizer { registry ->
			registry.config().commonTags("region", "us-east-1")
		}
	}

}

You can apply customizations to particular registry implementations by being more specific about the generic type:

Java
Kotlin

import io.micrometer.core.instrument.Meter;
import io.micrometer.core.instrument.config.NamingConvention;
import io.micrometer.graphite.GraphiteMeterRegistry;

import org.springframework.boot.actuate.autoconfigure.metrics.MeterRegistryCustomizer;
import org.springframework.context.annotation.Bean;
import org.springframework.context.annotation.Configuration;

@Configuration(proxyBeanMethods = false)
public class MyMeterRegistryConfiguration {

	@Bean
	public MeterRegistryCustomizer<GraphiteMeterRegistry> graphiteMetricsNamingConvention() {
		return (registry) -> registry.config().namingConvention(this::name);
	}

	private String name(String name, Meter.Type type, String baseUnit) {
		return ...
	}

}

import io.micrometer.core.instrument.Meter
import io.micrometer.core.instrument.config.NamingConvention
import io.micrometer.graphite.GraphiteMeterRegistry
import org.springframework.boot.actuate.autoconfigure.metrics.MeterRegistryCustomizer
import org.springframework.context.annotation.Bean
import org.springframework.context.annotation.Configuration

@Configuration(proxyBeanMethods = false)
class MyMeterRegistryConfiguration {

	@Bean
	fun graphiteMetricsNamingConvention(): MeterRegistryCustomizer<GraphiteMeterRegistry> {
		return MeterRegistryCustomizer { registry: GraphiteMeterRegistry ->
			registry.config().namingConvention(this::name)
		}
	}

	private fun name(name: String, type: Meter.Type, baseUnit: String?): String {
		return  ...
	}

}

Spring Boot also configures built-in instrumentation that you can control through configuration or dedicated annotation markers.
