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)

# SSH เข้า ASUSTOR

# กำหนดสิทธิ์ให้ตรงกับ User ID ใน Container
# Prometheus (UID 65534 - nobody)

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
grafana.np-dms.work	grafana	3000	[ ]	[x]	[x]	[x]	[x]

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:

# 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:

      - /var/run:/var/run:ro
      - /sys:/sys:ro
      - /var/lib/docker/:/var/lib/docker:ro

Prometheus Configuration

สร้างไฟล์ /volume1/np-dms/monitoring/prometheus/config/prometheus.yml บน ASUSTOR:
