+# Docker Monitoring Stack
+
+이 프로젝트는 Docker 컨테이너의 CPU, 메모리, 네트워크, 디스크 사용량을 모니터링하기 위한 Prometheus + Grafana 스택입니다.
+
+## 구성 요소
+
+- **Prometheus**: 메트릭 수집 및 저장
+- **Grafana**: 시각화 대시보드
+- **cAdvisor**: Docker 컨테이너 메트릭 수집
+- **Node Exporter**: 시스템 메트릭 수집
+
+## 사용 방법
+
+### 1. 스택 시작
+
+```bash
+./start.sh
+```
+
+또는 직접 docker-compose 사용:
+
+```bash
+docker-compose up -d
+```
+
+### 2. 접속 정보
+
+- **Grafana**: http://localhost:8883
+  - 사용자명: `admin`
+  - 비밀번호: `admin`
+  
+- **Prometheus**: http://localhost:8882
+- **cAdvisor**: http://localhost:8881
+- **Node Exporter**: http://localhost:9100
+
+### 3. 대시보드
+
+Grafana에 자동으로 프로비저닝되는 대시보드:
+- Docker Container Monitoring
+  - 컨테이너 CPU 사용률
+  - 컨테이너 메모리 사용량
+  - 네트워크 I/O
+  - 디스크 I/O
+
+### 4. 스택 중지
+
+```bash
+docker-compose down
+```
+
+### 5. 로그 확인
+
+```bash
+docker-compose logs -f
+```
+

+```
+
+## 주요 메트릭
+
+- `container_cpu_usage_seconds_total`: 컨테이너 CPU 사용시간
+- `container_memory_usage_bytes`: 컨테이너 메모리 사용량
+- `container_network_receive_bytes_total`: 네트워크 수신 바이트
+- `container_network_transmit_bytes_total`: 네트워크 송신 바이트
+- `container_fs_reads_bytes_total`: 디스크 읽기 바이트
+- `container_fs_writes_bytes_total`: 디스크 쓰기 바이트
+
+## 문제 해결
+
+1. **포트 충돌**: 다른 서비스에서 포트를 사용 중인 경우 docker-compose.yml의 포트를 변경하세요.
+2. **권한 문제**: cAdvisor가 Docker 메트릭에 접근하려면 권한이 필요합니다.
+3. **데이터 지속성**: Docker 볼륨을 사용하여 Prometheus와 Grafana 데이터가 보존됩니다.
