Metrics Example based on Prometheus and Grafana

Spring Boot Metrics Example

A Spring Boot application capturing metrics using Micrometer. Prometheus scrapes and stores the metrics whilst reporting is done in Grafana.

Start the Example

Prometheus scrapes the metrics using a HTTP call and therefore needs access to the running application. An easy way to achieve this, is to run the Spring Boot application in a Docker container too.

We therefore build a Docker image using jib and start it using Docker Compose.

./gradlew jibDockerBuild
docker-compose up -d

The example is accessible on:

• Spring Boot: http://localhost:8080
• Grafana: http://localhost:3000
  • User: admin
  • Password: admin
• Prometheus: http://localhost:9090

The Prometheus data source and a JVM dashboard are automatically provisioned in Grafana.
