+### 6. Grafana Dashboards Setup
+
+เพื่อการ Monitor ที่สมบูรณ์ แนะนำให้ Import Dashboards ต่อไปนี้:
+
+#### 6.1 Host Monitoring (Node Exporter)
+*   **Concept:** ดู resource ของเครื่อง Host (CPU, RAM, Disk, Network)
+*   **Dashboard ID:** `1860` (Node Exporter Full)
+*   **วิธี Import:**
+    1. ไปที่ **Dashboards** → **New** → **Import**
+    2. ช่อง **Import via grafana.com** ใส่เลข `1860` กด **Load**
+    3. เลือก Data source: **Prometheus**
+    4. กด **Import**
+
+#### 6.2 Container Monitoring (cAdvisor)
+*   **Concept:** ดู resource ของแต่ละ Container (เชื่อม Logs ด้วย)
+*   **Dashboard ID:** `14282` (Cadvisor exporter)
+*   **วิธี Import:**
+    1. ใส่เลข `14282` กด **Load**
+    2. เลือก Data source: **Prometheus**
+    3. กด **Import**
+
+#### 6.3 Logs Monitoring (Loki Integration)
+เพื่อให้ Dashboard ของ Container แสดง Logs จาก Loki ได้ด้วย:
+
+1. เปิด Dashboard **Cadvisor exporter** ที่เพิ่ง Import มา
+2. กดปุ่ม **Add visualization** (หรือ Edit dashboard)
+3. เลือก Data source: **Loki**
+4. ในช่อง Query ใส่: `{container="$name"}`
+    *   *(Note: `$name` มาจาก Variable ของ Dashboard 14282)*
+5. ปรับ Visualization type เป็น **Logs**
+6. ตั้งชื่อ Panel ว่า **"Container Logs"**
+7. กด **Apply** และ **Save Dashboard**
+
+ตอนนี้เราจะเห็นทั้ง **กราฟการกินทรัพยากร** และ **Logs** ของ Container นั้นๆ ในหน้าเดียวกันครับ
+
+#### 6.4 Integrated Dashboard (Recommended)
+
+ผมได้เตรียม JSON file ที่รวม Metrics และ Logs ไว้ให้แล้วครับ:
+
+1.  ไปที่ **Dashboards** → **New** → **Import**
+2.  ลากไฟล์ หรือ Copy เนื้อหาจากไฟล์:
+    `specs/08-infrastructure/grafana/dashboards/lcbp3-docker-monitoring.json`
+3.  กด **Load** และ **Import**
+
+## 7.3 Backup / Export Dashboards
+
+เมื่อปรับแต่ง Dashboard จนพอใจแล้ว ควร Export เก็บเป็นไฟล์ JSON ไว้ backup หรือ version control:
+
+1.  เปิด Dashboard ที่ต้องการ backup
+2.  ไปที่ปุ่ม **Share Dashboard** (ไอคอน 🔗 หรือ Share มุมซ้ายบน)
+3.  เลือกTab **Export**
+4.  เปิดตัวเลือก **Export for sharing externally** (เพื่อให้ลบ hardcoded value)
+5.  กด **Save to file**
+6.  นำไฟล์ JSON มาเก็บไว้ที่ path: `specs/08-infrastructure/grafana/dashboards/`
