📝 작업 내용

Grafana에서 Quespot 오류가 발생한 API를 식별할 수 있도록 공통 오류 메트릭에 요청 메서드와 템플릿화된 API 경로 라벨을 추가했습니다.

변경 사항

  • quespot_api_errors_total 메트릭에 method, uri 라벨 추가
  • 실제 요청 URI 대신 /api/missions/{missionId}와 같은 매칭 패턴을 사용해 메트릭 카디널리티 증가 방지
  • 매칭된 API 경로가 없는 경우 UNMATCHED 라벨 적용
  • Security 계층 등 요청 정보가 없는 기존 호출은 UNKNOWN, UNMATCHED로 호환
  • 공통 예외 처리기에서 요청 정보를 오류 메트릭에 전달하도록 수정
  • 메서드·경로 라벨 검증 테스트 추가
  • README 모니터링 설명 업데이트

📝 Walkthrough

Walkthrough

API 오류 메트릭이 오류 코드와 HTTP 상태 외에 요청 메서드와 템플릿화된 URI를 기록합니다. 예외 처리기는 HttpServletRequest를 메트릭 기록 호출에 전달합니다. 관련 테스트와 README 설명이 갱신되었습니다.

Changes

API 오류 메트릭 요청 정보 확장

Layer / File(s) Summary
메트릭 태그 생성
src/main/java/com/quespot/global/monitoring/ApiErrorMetrics.java
ApiErrorMetrics가 HTTP 메서드와 최적 매칭 URI 패턴을 method, uri 태그로 기록합니다. 값이 없으면 UNKNOWN_METHOD, UNMATCHED_URI를 사용합니다.
예외 처리기 요청 전달
src/main/java/com/quespot/global/apiPayload/handler/GeneralExceptionAdvice.java
예외 처리 메서드와 내부 응답 생성 메서드가 HttpServletRequest를 받고, 메트릭 기록 호출에 요청을 전달합니다.
동작 검증 및 메트릭 설명
src/test/java/com/quespot/global/monitoring/ApiErrorMetricsTest.java, src/test/java/com/quespot/global/apiPayload/handler/GeneralExceptionAdviceTest.java, README.md
테스트가 요청 메서드와 매칭 URI 태그를 검증합니다. README가 메트릭 집계 기준을 갱신합니다.

Arbitrary HTTP methods can increase metric cardinality, while fallback metric labels are unprotected by tests. The changes are localized and should be addressed before relying on these metrics.

In `@src/main/java/com/quespot/global/monitoring/ApiErrorMetrics.java`:
- Around line 25-30: Update ApiErrorMetrics.increment(BaseErrorCode,
HttpServletRequest) to normalize request.getMethod() before delegating to
increment(errorCode, method, uri): preserve recognized RequestMethod values and
convert any unrecognized HTTP method to the standard UNKNOWN value, preventing
arbitrary method metric series.

In `@src/test/java/com/quespot/global/monitoring/ApiErrorMetricsTest.java`:
- Around line 6-28: Extend ApiErrorMetricsTest with assertions for both fallback
paths: increment(BaseErrorCode) must produce code/status tags with
method=UNKNOWN and uri=UNMATCHED, while the request overload without
BEST_MATCHING_PATTERN_ATTRIBUTE must produce uri=UNMATCHED. Execute each call
and assert all four tags plus the expected counter value.
