# 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 (ASUSTOR) / 8088 (QNAP) | เก็บ Metrics ของ Docker containers | Both |
|
||
| **Uptime Kuma** | 3001 | Service Availability Monitoring | ASUSTOR |
|
||
| **Loki** | 3100 | Log aggregation | ASUSTOR |
|
||
| **Promtail** | - | Log shipper (Sender) | 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
|
||
mkdir -p /volume1/np-dms/monitoring/promtail/config
|
||
|
||
# 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)
|
||
chown -R 472:472 /volume1/np-dms/monitoring/grafana/data
|
||
chmod -R 750 /volume1/np-dms/monitoring/grafana/data
|
||
|
||
# Uptime Kuma (UID 1000)
|
||
chown -R 1000:1000 /volume1/np-dms/monitoring/uptime-kuma/data
|
||
chmod -R 750 /volume1/np-dms/monitoring/uptime-kuma/data
|
||
|
||
# Loki (UID 10001)
|
||
chown -R 10001:10001 /volume1/np-dms/monitoring/loki/data
|
||
chmod -R 750 /volume1/np-dms/monitoring/loki/data
|
||
|
||
# Promtail (Runs as root to read docker logs - no specific chown needed for config dir if created by admin)
|
||
# But ensure config file is readable
|
||
chmod -R 755 /volume1/np-dms/monitoring/promtail/config
|
||
```
|
||
|
||

|
||
|
||
## 🔗 สร้าง Docker Network (ทำครั้งแรกครั้งเดียว)
|
||
|
||
> ⚠️ **ต้องสร้าง network ก่อน deploy docker-compose ทุกตัว** เพราะทุก service ใช้ `lcbp3` เป็น external network
|
||
|
||
### สร้างผ่าน Portainer (แนะนำ)
|
||
|
||
1. เปิด **Portainer** → เลือก Environment ของ ASUSTOR
|
||
2. ไปที่ **Networks** → **Add network**
|
||
3. กรอกข้อมูล:
|
||
- **Name:** `lcbp3`
|
||
- **Driver:** `bridge`
|
||
4. กด **Create the network**
|
||
|
||
### สร้างผ่าน SSH
|
||
|
||
```bash
|
||
# SSH เข้า ASUSTOR
|
||
ssh admin@192.168.10.9
|
||
|
||
# สร้าง external network
|
||
docker network create lcbp3
|
||
|
||
# ตรวจสอบ
|
||
docker network ls | grep lcbp3
|
||
docker network inspect lcbp3
|
||
```
|
||
|
||
> 📖 **QNAP** ก็ต้องมี network ชื่อ `lcbp3` เช่นกัน (สร้างผ่าน Container Station หรือ SSH)
|
||
> ดู [README.md – Quick Reference](README.md#-quick-reference) สำหรับคำสั่งบน QNAP
|
||
|
||
---
|
||
|
||
## Note: NPM Proxy Configuration (NPM รันบน QNAP → Forward ไป ASUSTOR)
|
||
|
||
> ⚠️ เนื่องจาก NPM อยู่บน **QNAP** แต่ Monitoring services อยู่บน **ASUSTOR**
|
||
> ต้องใช้ **IP Address** (`192.168.10.9`) แทนชื่อ container (resolve ข้ามเครื่องไม่ได้)
|
||
|
||
| Domain Names | Scheme | Forward Hostname | Forward Port | Block Common Exploits | Websockets | Force SSL | HTTP/2 |
|
||
| :--------------------- | :----- | :--------------- | :----------- | :-------------------- | :--------- | :-------- | :----- |
|
||
| grafana.np-dms.work | `http` | `192.168.10.9` | 3000 | [x] | [x] | [x] | [x] |

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

## 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 |

### Step 1.2: สร้าง promtail-config.yml
|
||
|
||
ต้องสร้าง Config ให้ Promtail อ่าน logs จาก Docker containers และส่งไป Loki:
|
||
|
||
```bash
|
||
# สร้างไฟล์ promtail-config.yml
|
||
cat > /volume1/np-dms/monitoring/promtail/config/promtail-config.yml << 'EOF'

- source_labels: ['__meta_docker_container_log_stream']
|
||
target_label: 'stream'
|
||
EOF
|
||
|
||
# ตรวจสอบ
|
||
cat /volume1/np-dms/monitoring/promtail/config/promtail-config.yml
|
||
```
|
||
|
||
---
|
||
|
||
### Step 2: Deploy ผ่าน Portainer (แนะนำ)
|
||
|
||
1. เปิด **Portainer** → เลือก Environment ของ **ASUSTOR**
|
||
2. ไปที่ **Stacks** → **Add stack**
|
||
3. กรอกข้อมูล:
|
||
- **Name:** `lcbp3-monitoring`
|
||
- **Build method:** เลือก **Web editor**
|
||
4. วาง (Paste) เนื้อหาจาก [Docker Compose File (ASUSTOR)](#docker-compose-file-asustor) ด้านบน
|
||
5. กด **Deploy the stack**
|
||
|
||
> ⚠️ **สำคัญ:** ตรวจสอบ Password ของ Grafana (`GF_SECURITY_ADMIN_PASSWORD`) ใน docker-compose ก่อน deploy
|
||
|
||
### Deploy ผ่าน SSH (วิธีสำรอง)
|
||
|
||
```bash
|
||
# SSH เข้า ASUSTOR
|
||
ssh admin@192.168.10.9
|
||
|
||
# คัดลอก docker-compose.yml ไปยัง path
|
||
# (วางไฟล์ที่ /volume1/np-dms/monitoring/docker-compose.yml)
|
||
|
||
# Deploy
|
||
cd /volume1/np-dms/monitoring
|
||
docker compose up -d
|
||
|
||
# ตรวจสอบ container status
|
||
docker compose ps
|
||
```
|
||
|
||
---
|
||
|
||
### Step 3: Verify Services
|
||
|
||
```bash
|
||
# ตรวจสอบ containers ทั้งหมด
|
||
docker ps --filter "name=prometheus" --filter "name=grafana" \
|
||
--filter "name=uptime-kuma" --filter "name=node-exporter" \
|
||
--filter "name=cadvisor" --filter "name=loki" --filter "name=promtail"
|
||
```
|
||
|
||
| Service | วิธีตรวจสอบ | Expected Result |
|
||
| :---------------- | :----------------------------------------------------------------- | :------------------------------------ |
|
||
| ✅ **Prometheus** | `curl http://192.168.10.9:9090/-/healthy` | `Prometheus Server is Healthy` |
|
||
| ✅ **Grafana** | เปิด `https://grafana.np-dms.work` (หรือ `http://192.168.10.9:3000`) | หน้า Login |
|
||
| ✅ **Uptime Kuma** | เปิด `https://uptime.np-dms.work` (หรือ `http://192.168.10.9:3001`) | หน้า Setup |
|
||
| ✅ **Node Exp.** | `curl http://192.168.10.9:9100/metrics \| head` | Metrics output |
|
||
| ✅ **cAdvisor** | `curl http://192.168.10.9:8080/healthz` | `ok` |
|
||
| ✅ **Loki** | `curl http://192.168.10.9:3100/ready` | `ready` |
|
||
| ✅ **Promtail** | เช็ค Logs: `docker logs promtail` | ไม่ควรมี Error + เห็น connection success |
|
||
|

|
||
|
||
### Step 4: Deploy QNAP Exporters
|
||
|
||
ติดตั้ง node-exporter และ cAdvisor บน QNAP เพื่อให้ Prometheus scrape ข้ามเครื่องได้:
|
||
|
||
#### ผ่าน Container Station (QNAP)
|
||
|
||
1. เปิด **Container Station** บน QNAP Web UI
|
||
2. ไปที่ **Applications** → **Create**
|
||
3. ตั้งชื่อ Application: `lcbp3-exporters`
|
||
4. วาง (Paste) เนื้อหาจาก [QNAP Node Exporter & cAdvisor](#qnap-node-exporter--cadvisor)
|
||
5. กด **Create**
|
||
|
||
#### ตรวจสอบจาก ASUSTOR
|
||
|
||
```bash
|
||
# ตรวจว่า Prometheus scrape QNAP ได้
|
||
curl -s http://localhost:9090/api/v1/targets | grep -E '"qnap-(node|cadvisor)"'
|
||
|
||
# หรือเปิด Prometheus UI → Targets
|
||
# URL: http://192.168.10.9:9090/targets
|
||
# ดูว่า qnap-node, qnap-cadvisor เป็น State: UP
|
||
```
|
||
|
||

|
||
|
||
### Step 5: ตั้งค่า Grafana & Uptime Kuma
|
||
|
||
#### Grafana — First Login
|
||
|
||
1. เปิด `https://grafana.np-dms.work`
|
||
2. Login: `admin` / `Center#2025` (หรือ password ที่ตั้งไว้)
|
||
3. ไปที่ **Connections** → **Data sources** → **Add data source**
|
||
4. เลือก **Prometheus**
|
||
- URL: `http://prometheus:9090`
|
||
- กด **Save & Test** → ต้องขึ้น ✅
|
||
5. Import Dashboards (ดูรายละเอียดในหัวข้อ [6. Grafana Dashboards Setup](#6-grafana-dashboards-setup))
|
||
|
||
#### Uptime Kuma — First Setup
|
||
|
||
1. เปิด `https://uptime.np-dms.work`
|
||
2. สร้าง Admin account
|
||
3. เพิ่ม Monitors ตาม [ตาราง Uptime Kuma Monitors](#uptime-kuma-monitors)
|
||
|

|
||
|
||
### 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/`
