+## 복합키 구성
+
+- statTime (통계 시간)
+- apiName (API명)
+- gwInstanceId (Gateway 인스턴스 ID)
+- bizDivCode (업무구분코드)
+- clientId (클라이언트 ID)
+- inboundAdapter (Inbound Adapter)
+- outboundAdapter (Outbound Adapter)
+
+## 메트릭
+
+### 건수 메트릭
+- totalCnt: 총 처리 건수
+- successCnt: 성공 건수
+- timeoutCnt: Timeout 오류 건수
+- systemErrCnt: 시스템 오류 건수
+- bizErrCnt: 업무 오류 건수
+- seq900TimeoutCnt: 로그시퀀스900 Timeout 건수
+- seq900SystemErrCnt: 로그시퀀스900 시스템 오류 건수
+- seq900BizErrCnt: 로그시퀀스900 업무 오류 건수
+
+### 응답시간 메트릭 (ms)
+- avgRespTime: 평균 응답시간
+- minRespTime: 최소 응답시간
+- maxRespTime: 최대 응답시간
+- p50RespTime: 50 백분위 응답시간
+- p95RespTime: 95 백분위 응답시간
+
+## Multi-tenancy
+
+API Gateway 통계는 `APIGW` 스키마에 저장됩니다.
+Controller에서 `DataSourceContextHolder`를 사용하여 스키마를 전환합니다.
+
+```java
+DataSourceContextHolder.setDataSourceType(
+    DataSourceTypeManager.getDataSourceType(DataSourceTypeManager.APIGW));
+```
+
+## 검색 조건
+
+- 조회기간 (시작~종료)
+- API명 (like 검색)
+- Gateway 인스턴스 ID
+- 업무구분코드 (like 검색)
+- 클라이언트 ID (like 검색)
+
+## 기술 스택
+
+- JPA + QueryDSL
+- MapStruct (Entity ↔ UI 매핑)
+- Spring MVC (ResponseEntity)
+- jqGrid (목록 화면)
