Chore/#224 Actuator·Prometheus·Grafana 모니터링 시스템 구축 - #228
Conversation
- ClientResourcesBuilderCustomizer 빈으로 GET/SET/EXPIRE 등 커맨드별 레이턴시 수집 - 클릭 윈도우/급증 감지 등 RedisTemplate 직접 호출 경로 성능 확인용
- @timed 애노테이션을 실제 동작시키는 AOP 빈 - @scheduled 메서드에 @timed를 붙이면 실행시간/실패율이 자동으로 지표화됨
- hibernate.generate_statistics 로 hibernate.* 지표(쿼리 실행 수 등) 수집 - http.server.requests 히스토그램 활성화로 p95/p99 latency 계산 가능하게 함
- spring.kafka.listener.observation-enabled: @KafkaListener 처리시간/에러 지표 - spring.kafka.template.observation-enabled: KafkaTemplate.send() 지표 - ClickConsumer, NotificationConsumer 등 클릭 트래킹 파이프라인 성능 확인용
- /actuator/** 를 JWT 체인과 분리된 별도 SecurityFilterChain(@order(1))으로 보호 - 기존엔 로그인한 일반 사용자(JWT 보유자)도 /actuator/env 로 전체 환경변수(DB 비번, JWT 시크릿 등) 조회가 가능했는데, 이 경로도 함께 차단됨 - actuator-auth.username/password 프로퍼티로 Prometheus 스크레이핑 전용 계정 관리 - 로컬용 monitoring/prometheus.yml 에도 동일 계정(local-dev-only) 반영
- prometheus 서비스가 where-you-ad-network 에 미포함이라 app 컨테이너를 이름으로 못 찾던 문제 수정 - 로컬(host.docker.internal)과 달리 dev는 같은 네트워크의 app:8080 을 직접 스크레이핑 - monitoring/prometheus.dev.yml.example 추가 (실제 계정정보 포함 파일은 .env 처럼 gitignore 처리)
- docker-compose.yml 에 grafana 서비스 추가 (127.0.0.1 바인딩, GRAFANA_ADMIN_PASSWORD 로 인증) - monitoring/grafana/provisioning: Prometheus datasource, 대시보드 자동 로드 설정 - monitoring/grafana/dashboards/whereyouad-monitoring.json: Overview/DB-N+1/Kafka/Redis/Scheduler/JVM 6개 row 대시보드 - .env.example 에 ACTUATOR_METRICS_*, GRAFANA_ADMIN_PASSWORD 플레이스홀더 문서화
- GF_AUTH_ANONYMOUS_ENABLED: 로컬 전용, 로그인 없이 바로 대시보드 확인 - monitoring/grafana/provisioning, dashboards 볼륨 마운트로 dev와 동일한 대시보드 자동 로드
- prometheus-data 볼륨 추가 - 컨테이너 재생성(down/recreate)해도 리팩토링 전후 지표 유지 - --storage.tsdb.retention.time=90d 로 기본 15일보다 넉넉하게 보존
- prometheus-data-local 볼륨 추가 - docker-compose down 해도 로컬 테스트 지표 유지
- monitoring/prometheus.dev.yml 은 .gitignore 대상이라 git reset --hard로는 서버에 안 올라감 - PROD_ENV_FILE과 동일한 패턴으로 PROMETHEUS_DEV_YML secret을 파일로 풀어써서 배포 시 자동 생성
- 자체 인증이 없는 Prometheus 웹 UI(9090)가 EC2 전체 공개 상태였음 - Grafana(3000)와 동일하게 로컬 바인딩으로 제한, SSH 터널/VPN으로만 접근하도록 변경
WalkthroughActuator와 Micrometer 메트릭 수집을 추가했습니다. Prometheus가 애플리케이션 메트릭을 스크랩합니다. Grafana가 API, DB, Kafka, Redis, 스케줄러, JVM 지표를 시각화합니다. 배포 과정에서 Prometheus 설정을 Secret으로 생성합니다. Changes모니터링 환경
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to 모니터링 기능은 추가되지만, Actuator 인증 누락 시 약한 자격 증명이 적용될 수 있고 로컬 모니터링 노출 및 배포 Secret 처리에도 보안 위험이 남아 있습니다. N+1 대시보드도 대상 API의 쿼리 수를 정확히 나타내지 않으므로 병합 전에 수정하거나 명시적으로 수용해야 합니다. Suggested reviewers: Sequence Diagram(s)sequenceDiagram

요청 범위의 쿼리 수를 집계하는 별도 메트릭으로 교체하세요.
현재 쿼리는 uri 필터나 그룹이 없습니다. hibernate_statements_total과 전체 HTTP 요청 수를 사용하므로 Kafka 소비, 스케줄러, 동시 요청의 쿼리가 함께 계산됩니다. 정규화된 URI를 태그로 기록하는 요청 범위 메트릭을 사용해야 특정 API의 N+1 개선을 측정할 수 있습니다.

METRICS 계정의 Actuator 권한을 최소화하세요.
Prometheus는 /actuator/prometheus만 필요합니다. 현재 env와 loggers도 노출됩니다. SecurityConfig.java의 Line 75는 METRICS 계정에 모든 /actuator/** 요청을 허용합니다.
자격 증명이 노출되면 사용자가 환경 설정을 조회하고 런타임 로그 레벨을 변경할 수 있습니다. env와 loggers를 노출 목록에서 제거하세요. 운영 진단이 필요하면 별도 역할과 내부 네트워크 제한을 사용하세요.

P4 : 고생하셨습니다! 모니터링 시스템은 저는 처음 보는거여서 좀 더 공부해봐야 제대로 알 것 같긴 하지만... 잘 구현해주신거 같습니다 👍 혹시라도 사용하다가 질문 생기면 더 물어보겠습니다.
스케줄러 지표를 @Timed 어노테이션 으로 확인하는것도 좋은거 같아요..!! 잘 모르긴 하지만 찾아봤을 때는 저희 프로젝트에서 SSE 로 실시간 클릭을 전달하는 DashboardClickServiceImpl.broadcastRealTimeClicks() 메서드가 1초마다 Scheduled 로 실행되는 구조라서 이 메서드가 성능 검사에 좋을 것 같은데, 이 클래스가 인터페이스 구현체여서 단순 timed 어노테이션 적용이 안된다고 하긴 하네요... 이 부분은 별도 적용법이 있다고 해서 추후에 리팩터링으로 적용하면 좋을 것 같습니다..!!

Prometheus, Grafana 등을 제가 처음 접하는거여서 클로드로 코드 보면서 설명을 요청했는데 이렇게 docker-compose.yml 에 환경변수 누락이 있다고 하는데 수정해야되는거 맞을까요...??

P2: 고생하셨습니다..! 들어가서 보는데 매우매우 신기하네요.. 아직 지표들을 잘 못봐서..! 공부하면서 리펙터링 전에 지표 측정 -> 리펙터링 -> 지표 측정 순으로 하면 도움이 많이 될 것 같아요! 감사합니다!!
추가로 카프카 p95도 잘 안보이는 것 같은데 저만 그럴까요..?

- percentiles-histogram이 http.server.requests에만 켜져있어 spring.kafka.listener/template의 _bucket 시리즈가 안 생기던 문제 - histogram_quantile() 은 _bucket이 있어야 계산되므로 Kafka p95/p99 패널이 항상 빈 값이었음 - @kingmingyu 리뷰 반영
- MicrometerOptions.create() 는 기본값이 histogram=false 라 _bucket 시리즈가 안 생기던 문제 - MicrometerOptions.builder().histogram(true).build() 로 변경 - @kingmingyu 리뷰 반영
- 기존엔 METRICS 계정 하나로 /actuator/env(전체 환경변수), /actuator/loggers 까지 접근 가능했음 - /actuator/prometheus, /actuator/health* 만 허용하고 나머지는 denyAll() 로 차단 (least privilege) - @kingmingyu 리뷰 반영
- @timed(value="scheduler.execution", extraTags={"job","meta-ad-sync"}) 적용 - @kingmingyu 리뷰 반영

appleboy/ssh-action README env envs script remote environment variables
💡 Result:
To pass environment variables to a remote script using the appleboy/ssh-action, you must define the variables in the step's env block and explicitly list their names in the envs parameter [1][2]. 1. Define the variables in the env object: Use the standard GitHub Actions env syntax to define your environment variables [1][3]. 2. List variables in the envs parameter: Provide a comma-separated string of the variable names you wish to pass to the remote shell [1][4]. Example configuration: - name: Pass environment uses: appleboy/ssh-action@v1 env: FOO: "BAR" SHA: ${{ github.sha }} with: host: ${{ secrets.HOST }} username: ${{ secrets.USERNAME }} key: ${{ secrets.KEY }} envs: FOO,SHA script: | echo "I am $FOO" echo "sha: $SHA" Important notes: - String requirement: All environment variables in the env object must be strings; passing other data types may result in unexpected behavior [1][5]. - All-environment mode: Alternatively, you can set allenvs: true to pass all environment variables prefixed with GITHUB_ and INPUT_ to the script automatically [1][4]. - Custom formatting: If you need a specific export format, you can use the envs_format parameter (e.g., export TEST_{NAME}={VALUE}) to customize how variables are transferred [4].

Secret을 script에 직접 삽입하지 마세요.
.github/workflows/cd.yml:71-76의 세 secret은 원격 셸이 해석하는 script 문자열에 직접 삽입됩니다. 값에 $(), backtick 또는 따옴표가 포함되면 명령 실행이나 문자열 탈출이 발생할 수 있습니다. env와 envs로 전달한 뒤 printf '%s' "$PROD_ENV_FILE"처럼 인용하여 사용하세요.

around the Prometheus configuration generation and the other three secrets to
pass values through the action’s env/envs mechanism instead of interpolating
secrets directly into the script. In the remote shell, reference each
environment variable with quoted parameter expansion and use printf for file
contents, preserving the existing secret-to-file behavior.

@ojy0903 @kingmingyu 리뷰해주신 사항 토대로 수정 완료했습니다! @timed 어노테이션은 찾아보니 현재는 JDK 프록시를 쓰고 있지 않아서, 인터페이스 구현 유무에 상관 없이 실제 클래스 프록시에 적용되기에 문제 없을 듯 하여 우선 각 광고 플랫폼 동기화 스케줄러에 모두 적용하였습니다! |

Actuator 비밀번호가 비어 있는 배포를 차단하세요.
docker-compose.yml은 변수가 없을 때 ACTUATOR_METRICS_PASSWORD에 빈 문자열을 전달합니다. application.yml의 기본값은 빈 문자열을 대체하지 않습니다. 따라서 빈 비밀번호로 Actuator Basic Auth가 성공할 수 있습니다. 다음과 같이 필수 보간을 사용하세요.

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Close #224
🚀 개요
Actuator + Prometheus + Grafana 기반 모니터링 시스템을 구축했습니다.
(Actuator는 서버 상태(메모리, CPU 등)를 수치로 뽑아내고, Prometheus는 이 메트릭을 주기적으로 긁어 모아 데이터를 수집하는 용도이고, Grafana가 이를 시각적인 그래프로 보여주는 대시보드 역할을 함)
📄 작업 내용
의존성/기본 설정: spring-boot-starter-actuator, micrometer-registry-prometheus 추가, Actuator 엔드포인트 노출 설정
주요 모니터링 지표
docker 설정 추가 및 변경
Grafana
📊 모니터링 사용 가이드
로컬에서 확인하기
배포 후 (dev 서버) 확인하기
Grafana(3000)·Prometheus(9090) 둘 다 보안상 dev 서버의 127.0.0.1에만 열려있어서, SSH 터널로 접속해야 함. (Public->Private EC2 안 까지 들어가야함)
터널 연결 후 로컬 브라우저에서 그대로 localhost:3000, localhost:9090 접속 후 비밀번호(노션 환경 변수 페이지) 입력 시 확인 가능

🔍 리뷰 포인트 (Review Points)
초기 설계했던 아키텍처에도 모니터링 시스템이 있기도 했고, 캡스톤 발표 전까지 각자 리팩토링 진행하면서 전후 지표(N+1 쿼리 개선, Kafka, 스케줄러, Redis 등)를 정량적으로 비교해서 정리하면 좋을 것 같아 추가했습니다! (ex. N+1 개선 시 "요청당 쿼리 수 47개 → 3개", API p95 응답속도 "320ms → 80ms"처럼 리팩토링 전/후를 실제 수치로 비교 가능)
또는 서버 내부 에러 급증 시 Discord 알림을 붙이거나 부하테스트 결과를 이 대시보드에 연계하거나 확장해볼 수 있을 듯 합니다.
로그인 계정/비밀번호는 노션 공용 페이지에 정리해두었고, 더 추가하고 싶은 지표가 있다면 추가해주셔도 좋을 것 같아요!
