Monitoring

Overview

Old infra

• Grafana 🚀 : A dashboard to show all monitored metrics.
• Prometheus 🚀 : A tool to monitor and collect systems and services metrics.
• Influx-DB 🚀 : An equivalent to Prometheus
• Exporters :
  • Node Exporter 🚀 : Export system metrics
  • Cadvisor 🚀 : Export container CPU/Memory usage metrics
  • Watchtower
  • Promtail : read logs file and export their content
  • Loki : Intermediate between Promtail and InfluxDb

New infra

I switch to using only Beszel with Beszel agent on other hosts, it’s way simpler to setup and still really complete (and with Docker support).

Setup

services:
  beszel:
    image: henrygd/beszel:0.10.2
    container_name: beszel_hub
    restart: unless-stopped
    ports:
      - 8090:8090
    volumes:
      - /data/apps/monitoring/beszel_data:/beszel_data
    networks:
      - homelab
    labels:
      - traefik.enable=true
      - traefik.http.routers.beszel.rule=Host(`beszel.zrx.sh`)
      - traefik.http.services.beszel.loadbalancer.server.port=8090
      - traefik.http.routers.beszel.middlewares=homelab-whitelist@file
      - traefik.http.routers.beszel.tls=true
      - traefik.http.routers.beszel.tls.certresolver=production
      - traefik.http.routers.beszel.tls.domains[0].main=zrx.sh
      - traefik.http.routers.beszel.tls.domains[0].sans=*.zrx.sh
  beszel-agent:
    image: henrygd/beszel-agent:0.10.2
    container_name: beszel-rpi_agent
    restart: unless-stopped
    network_mode: host
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /mnt/hdd1/.beszel:/extra-filesystems/hdd1:ro
    environment:
      PORT: ${PORT}
      KEY: ${KEY}
networks:
  homelab:
    external: true
