spring boot + prometheus + grafana

의존성 추가

• spring boot actuator 공식문서
• spring boot prometheus 공식문서

dependencies {
	implementation("org.springframework.boot:spring-boot-starter-actuator")
	runtimeOnly("io.micrometer:micrometer-registry-prometheus")
    ...생략...
}

spring boot 실행

scrape_configs:
  - job_name: 'spring-actuator'
    metrics_path: '/actuator/prometheus'
    static_configs:
      - targets: ['localhost:8080']

docker 실행
