Monitoring Docker Container with prometheus + cadvisor + grafana + node-exporter

I will show you how to install all tools for monitor docker container by prometheus + cadvisor + grafana + node-exporter

1. Create docker-compose.yml

version: '3.2'
volumes:
  prometheus_data: {}
  grafana_data: {}
services:
  prometheus:
    image: prom/prometheus:latest
    container_name: monitoring_prometheus
    restart: unless-stopped
    volumes:
      - ./prometheus.yml:/etc/prometheus/prometheus.yml
      - prometheus_data:/promtheus
    command:
      - '--config.file=/etc/prometheus/prometheus.yml'
    expose:
      - 9090
    ports:
      - 9090:9090
    links:
      - cadvisor:cadvisor
      - node-exporter:node-exporter
  node-exporter:
    image: prom/node-exporter:latest
    container_name: monitoring_node_exporter
    restart: unless-stopped
    expose:
      - 9100

  cadvisor:
    image: gcr.io/cadvisor/cadvisor:v0.46.0
    container_name: monitoring_cadvisor
    restart: unless-stopped
    privileged: true
    devices:
      - /dev/kmsg:/dev/kmsg
    volumes:
      - /var/run:/var/run:ro
      - /sys:/sys:ro
      - /var/lib/docker/:/var/lib/docker:ro
      - /var/run/docker.sock:/var/run/docker.sock:ro
      - /etc/machine-id:/etc/machine-id:ro
      - /var/lib/dbus/machine-id:/var/lib/dbus/machine-id:ro
    expose:
      - 8080

  grafana:
    image: grafana/grafana:latest
    container_name: monitoring_grafana
    restart: unless-stopped
    links:
      - prometheus:prometheus
    volumes:
      - ./data/grafana:/var/lib/grafana
    environment:
      - GF_SECURITY_ADMIN_PASSWORD=adminpassword
      - GF_USERS_ALLOW_SIGN_UP=false
    depends_on:
      - prometheus
    ports:
      - "3000:3000"

2. Create prometheus.yml (config file)

global:
  scrape_interval: 120s # By default, scrape targets every 15 seconds.
  evaluation_interval: 120s # By default, scrape targets every 15 seconds.
  external_labels:
    monitor: "my-project"
rule_files:
scrape_configs:
  - job_name: "prometheus"
    scrape_interval: 120s
    static_configs:
      - targets:
          [
            "localhost:9090",
            "cadvisor:8080",
            "node-exporter:9100",
            "nginx-exporter:9113",
          ]

3. run docker-compose up -d

4. http://localhost:3000 and select menu Data source

if localhost:9090 not work just try http://host.docker.internal:9090

5. Import dashboard from https://grafana.com/grafana/dashboards/10566-docker-and-os-metrics/

and then you will get it 😘

sometime some box will not display data you can edit query for modify your dashboard

Thank you 👌
