    image: prom/prometheus:latest
    container_name: prometheus
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
    ports:
      - 9090:9090
  grafana:
    image: grafana/grafana:latest
    container_name: grafana
    ports:
      - 3000:3000
    env_file:

Prometheus Configuration (e.g. Docker for Mac)

global:
  scrape_interval:     15s
  evaluation_interval: 15s
  external_labels:
    monitor: 'codelab-monitor'

rule_files:
#   - './alert.rules'

scrape_configs:
  - job_name: 'prometheus'
    static_configs:
      - targets:
          - 'docker.for.mac.host.internal:9090'
  - job_name: 'spring'
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets:
          - 'docker.for.mac.host.internal:8080'

  - job_name: 'admin'
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets:
          - 'docker.for.mac.host.internal:8110'
  - job_name: 'contents'
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets:
          - 'docker.for.mac.host.internal:8200'
  - job_name: 'discovery'
    metrics_path: '/prometheus'
    static_configs:
      - targets:
          - 'docker.for.mac.host.internal:8100'
  - job_name: 'frontend'
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets:
          - 'docker.for.mac.host.internal:8201'
  - job_name: 'gw'
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets:
          - 'docker.for.mac.host.internal:8000'
  - job_name: 'zipkin-server'
    metrics_path: '//actuator/prometheus'
    static_configs:
      - targets:
          - 'docker.for.mac.host.internal:9411'

You should change docker.for.mac.host.internal to the host address.

Grafana Configuration

Import Java Micrometer Basics.json to your Grafana Server or find this Dashboard(ID: 4683) on Grafana.com.

Spring Boot Configuration

dependencies {
    ...
    compile 'org.springframework.boot:spring-boot-starter-actuator'
    compile 'io.micrometer:micrometer-spring-legacy:1.0.6'
    compile 'io.micrometer:micrometer-registry-prometheus:1.0.6'  // You should add this line for prometheus.
    ...

Prometheus Panel

Grafana JVM Micrometer

You can start a sample project of Spring Boot (Ver.2.5.4) with this proto folder outside of containers.
