Micrometer Prometheus integration¶

Micrometer is an instrumentation library that provides a facade for application Metrics, allowing developers to expose monitoring data to Prometheus without being tightly coupled to the Prometheus client directly.^[400-devops__03-Containerization__prometheus.md]

Integration¶

To enable Prometheus Metrics in a Java application, the micrometer-registry-prometheus dependency must be included in the project configuration.^[400-devops__03-Containerization__prometheus.md]

For Maven-based projects, the following runtime dependency is added:

<dependency>
  <groupId>io.micrometer</groupId>
  <artifactId>micrometer-registry-prometheus</artifactId>
  <scope>runtime</scope>
</dependency>

Role in Monitoring¶

Once integrated, Micrometer handles the collection and transformation of metric data into a format that Prometheus can scrape. This setup is commonly used within Kubernetes environments to monitor application performance alongside infrastructure Metrics.^[400-devops__03-Containerization__prometheus.md]
