# การติดตั้ง Monitoring Stack บน ASUSTOR
## **📝 คำอธิบายและข้อควรพิจารณา**
> ⚠️ **หมายเหตุ**: Monitoring Stack ทั้งหมดติดตั้งบน **ASUSTOR AS5403T** ไม่ใช่ QNAP
> เพื่อแยก Application workload ออกจาก Infrastructure/Monitoring workload
Stack สำหรับ Monitoring ประกอบด้วย:
| Service | Port | Purpose | Host |
| :---------------- | :--- | :-------------------------------- | :------ |
| **Prometheus** | 9090 | เก็บ Metrics และ Time-series data | ASUSTOR |
| **Grafana** | 3000 | Dashboard สำหรับแสดงผล Metrics | ASUSTOR |
| **Node Exporter** | 9100 | เก็บ Metrics ของ Host system | Both |
| **cAdvisor** | 8080 | เก็บ Metrics ของ Docker containers | Both |
| **Uptime Kuma** | 3001 | Service Availability Monitoring | ASUSTOR |
| **Loki** | 3100 | Log aggregation | ASUSTOR |

## กำหนดสิทธิ (บน ASUSTOR)
```bash
# SSH เข้า ASUSTOR
ssh admin@192.168.10.9
# สร้าง Directory
mkdir -p /volume1/np-dms/monitoring/prometheus/data
mkdir -p /volume1/np-dms/monitoring/prometheus/config
mkdir -p /volume1/np-dms/monitoring/grafana/data
mkdir -p /volume1/np-dms/monitoring/uptime-kuma/data
mkdir -p /volume1/np-dms/monitoring/loki/data
# กำหนดสิทธิ์ให้ตรงกับ User ID ใน Container
# Prometheus (UID 65534 - nobody)
chown -R 65534:65534 /volume1/np-dms/monitoring/prometheus
chmod -R 750 /volume1/np-dms/monitoring/prometheus
# Grafana (UID 472)

## Note: NPM Proxy Configuration (ถ้าใช้ NPM บน ASUSTOR)
| Domain Names | Forward Hostname | IP Forward Port | Cache Assets | Block Common Exploits | Websockets | Force SSL | HTTP/2 |
| :--------------------- | :--------------- | :-------------- | :----------- | :-------------------- | :--------- | :-------- | :----- |

| uptime.np-dms.work | uptime-kuma | 3001 | [ ] | [x] | [x] | [x] | [x] |
> **หมายเหตุ**: ถ้าใช้ NPM บน QNAP เพียงตัวเดียว ให้ forward ไปยัง IP ของ ASUSTOR (192.168.10.9)

## QNAP Node Exporter & cAdvisor
ติดตั้ง node-exporter และ cAdvisor บน QNAP เพื่อให้ Prometheus บน ASUSTOR scrape metrics ได้:
```yaml
# File: /share/np-dms/monitoring/docker-compose.yml (QNAP)
# เฉพาะ exporters เท่านั้น - metrics ถูก scrape โดย Prometheus บน ASUSTOR
version: '3.8'
networks:
lcbp3:
external: true
services:
node-exporter:
image: prom/node-exporter:v1.7.0
container_name: node-exporter
restart: unless-stopped
command:
- '--path.procfs=/host/proc'
- '--path.sysfs=/host/sys'
- '--collector.filesystem.mount-points-exclude=^/(sys|proc|dev|host|etc)($$|/)'
networks:
- lcbp3
volumes:
- /proc:/host/proc:ro
- /sys:/host/sys:ro
- /:/rootfs:ro
cadvisor:
image: gcr.io/cadvisor/cadvisor:v0.47.2
container_name: cadvisor
restart: unless-stopped
networks:
- lcbp3
volumes:
- /:/rootfs:ro
- /var/run:/var/run:ro
- /sys:/sys:ro
- /var/lib/docker/:/var/lib/docker:ro
```

## Uptime Kuma Monitors
เมื่อ Uptime Kuma พร้อมใช้งาน ให้เพิ่ม monitors ต่อไปนี้:
| Monitor Name | Type | URL / Host | Interval |
| :------------ | :--- | :--------------------------------- | :------- |
| QNAP NPM | HTTP | https://npm.np-dms.work | 60s |
| Frontend | HTTP | https://lcbp3.np-dms.work | 60s |
| Backend API | HTTP | https://backend.np-dms.work/health | 60s |
| MariaDB | TCP | 192.168.10.8:3306 | 60s |
| Redis | TCP | 192.168.10.8:6379 | 60s |
| Elasticsearch | HTTP | http://192.168.10.8:9200 | 60s |
| Gitea | HTTP | https://git.np-dms.work | 60s |
| n8n | HTTP | https://n8n.np-dms.work | 60s |
| Grafana | HTTP | https://grafana.np-dms.work | 60s |
| QNAP Host | Ping | 192.168.10.8 | 60s |
| ASUSTOR Host | Ping | 192.168.10.9 | 60s |

## Grafana Dashboards
### Recommended Dashboards to Import
| Dashboard ID | Name | Purpose |
| :----------- | :--------------------------- | :------------------ |
| 1860 | Node Exporter Full | Host system metrics |
| 14282 | cAdvisor exporter | Container metrics |
| 11074 | Node Exporter for Prometheus | Node overview |
| 7362 | Docker and Host Monitoring | Combined view |
### Import Dashboard via Grafana UI
1. Go to **Dashboards → Import**
2. Enter Dashboard ID (e.g., `1860`)
3. Select Prometheus data source
4. Click **Import**
