KPI 엔진 — 기관별 핵심 성과 지표 정의·계산·추적
|
|
|
|
기능:
|
|
- KPI 정의 (공식, 단위, 목표값, 방향성)
|
|
- 일별/주별/월별 자동 계산 (APScheduler)
|
|
- 목표 대비 달성률 및 신호등 상태 (RED/YELLOW/GREEN)
|
|
- 기존 analytics.py / sla.py 데이터 활용
|
|
|
|
내장 KPI 템플릿:
|
|
- MTTR: 평균 복구 시간 (시간 단위, 낮을수록 좋음)
|
|
- FCR: 첫 번째 해결율 (%, 높을수록 좋음)
|
|
- SLA_COMPLIANCE: SLA 준수율 (%, 높을수록 좋음)
|
|
- SR_BACKLOG: SR 적체 건수 (낮을수록 좋음)
|
|
- DEPLOY_SUCCESS_RATE: 배포 성공률 (%, 높을수록 좋음)
|
|
|
|
엔드포인트:
|
|
GET /api/kpi/ — KPI 목록 + 최신 값
|
|
POST /api/kpi/ — KPI 정의 생성
|
|
GET /api/kpi/{id} — KPI 상세 + 이력
|
|
PUT /api/kpi/{id} — KPI 수정
|
|
DELETE /api/kpi/{id} — KPI 삭제
|
|
POST /api/kpi/{id}/calculate — KPI 수동 재계산
|
|
GET /api/kpi/dashboard — 대시보드 요약 (전체 KPI 신호등)
|
|
GET /api/kpi/templates — 내장 KPI 템플릿 목록
|
|
POST /api/kpi/apply-template — 템플릿으로 KPI 일괄 등록
