How matches are found. Word for word: the exact same text. Edited: shares passages with this file (“99% same” means 99% of its five-word phrases also appear here; 10% or more counts). Their own version: similar meaning, or, weakest, the same name. We can’t tell which project had it first. Projects are counted among the 200 most-starred candidates, and mentions are links to the repository we found, up to 50 per site, so both counts are a floor.

/observability — 런타임 관측 스킬
대상: bstack 을 사용하는 프로젝트의 런타임 (bstack 자체 아님). 범위: Logging · Monitoring · Slack alerting 설계와 설정.
상세 의존성·코드 샘플·logback XML 전체는
docs/OBSERVABILITY.md참조. 이 SKILL.md는 언제/어떻게/decision tree 만.
When to use
- 새 프로젝트 로깅·모니터링 초기 설정
- 장애 후 알림 누락 원인 추적 및 보강
- Slack 알림 채널 추가/중복 알림 억제
- 대시보드(Grafana) 기본 세트 구성
- SLO 위반 감지 임계치 설정
How
1. Logging — Logback JSON + MDC
- 의존성:
logstash-logback-encoder - MDC 키:
traceId,userId,requestUri,method - 레벨 정책:
INFO: 비즈니스 경계 (주문 생성, 결제 완료)WARN: 회복 가능 비정상 (retry 성공, fallback 동작)ERROR: 알림 대상 (retry 실패, 예상 외 예외)
2. Monitoring — Actuator + Micrometer Prometheus
- 의존성:
spring-boot-starter-actuator,micrometer-registry-prometheus - 노출:
/actuator/prometheus - 커스텀 타이머: 주요 서비스 메서드에
@Timed - 필수 대시보드 3종: JVM (heap/gc/thread) · HikariCP (active/wait) · HTTP (RED — rate/error/duration)
3. Slack alerting — 2가지 옵션
옵션 A (추천, bstack 외부): Grafana/Prometheus Alertmanager → Slack webhook
- 장점: 앱 재시작 없이 규칙 변경, 표준 alerting
- 적합: 인프라 제어 가능한 팀
옵션 B (앱 내부): Spring WebClient 기반 SlackNotifier + @Async + ApplicationEventPublisher/@EventListener
- 장점: 도메인 이벤트와 직접 연결, 인프라 의존 없음
- 중복 억제:
ConcurrentHashMap<fingerprint, ts>— 동일 error fingerprint 5분 1회 - 적합: 인프라 제어 불가, ERROR 수준 즉시 알림만 필요
4. 임계치 예시 (Alertmanager 규칙)
| 지표 | 임계 | window |
| 에러율 | > 1% | 5분 |
| HTTP p99 | > 500ms | 5분 |
| HikariCP 대기 | > 100ms | 5분 |
| JVM heap | > 85% | 10분 |
| Full GC 빈도 | > 1/min | 5분 |

├── 인프라 제어 가능? (Prometheus/Alertmanager 운용 중)
│ └── 예 → 옵션 A (Alertmanager → webhook)
├── 아니오
│ ├── ERROR 레벨만 알림 → 옵션 B (SlackNotifier)
│ └── 비즈니스 이벤트 알림 (주문 N건, 결제 실패 등)
│ → 옵션 B + ApplicationEventPublisher
└── 둘 다 → A 우선, 앱 내 이벤트는 B 로 보강
로그 설계

├── 기존 plaintext → 점진 교체 (환경변수로 encoder 전환)
└── 멀티모듈 → 공통 모듈에 logback-spring.xml 제공References

Does it work?
Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.
No reviews yet
People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.
- It worked
- Partly
- It didn't
Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
Your trail
Files you open will collect here, so you can find them again.
Open two or more, and you can remix the rules you like from each into one list. Kept in this browser only.
Now do this for your own.
Bring your CLAUDE.md, AGENTS.md or skills. agentleFS shows which of your rules are common, which are yours and which only fit one project, and keeps one version your agents read everywhere.
