[모니터링] Docker + Prometheus + Grafana에 설치하기

 

 

 

Docker + docker-compose 설치

docker 설치 및 docker-compose 설치는 이미 설치했다고 가정한다. 만약 설치하지 않았다면 다음 url에서 설치 할 수 있다.

[Docker] Docker 부터 docker compose 설치

 

Spring build.gradle 파일에 추가

dependencies{	
    // monitoring
    implementation 'org.springframework.boot:spring-boot-starter-actuator'
    implementation 'io.micrometer:micrometer-registry-prometheus'
    ...
    
 }

 

application.yml파일 추가

localhost:8080/actuator/prometheus 호출해볼것

docker-compose.yml
