This is a basic example of collecting metrics from Traefik and CrowdSec using Prometheus and visualizing them with Grafana dashboards.
Important for users with low-powered server (1GB RAM): This setup will increase the use of your server RAM.

​
Configuration

​
Traefik

For claiming metrics from Traefik we have to adjust some configuration files.
  1. Udpate the docker-compose.yml file of the Pangolin stack to expose metrics port 8082 for the Prometheus connection:
service:
  gerbil:
    ports:
      - 8082:8082
Docker’s NAT-based port publishing feature automatically exposes all ports: defined in docker-compose file. This behavior can bypass your host firewall settings, potentially exposing services that you did not intend to make public. Please see complete warning about exposing ports.
  1. Update the /config/traefik/traefik_config.yml file to include the following:
entryPoints:
  metrics:
    address: ":8082"

metrics:
  prometheus:
    buckets:
      - 0.1
      - 0.3
      - 1.2
      - 5.0
    entryPoint: metrics
    addEntryPointsLabels: true
    addRoutersLabels: true
    addServicesLabels: true
  1. Restart the Gerbil and Traefik container to apply the changes:
sudo docker restart traefik gerbil

​
Crowdsec

For claiming metrics from Crowdsec we have to adjust the docker compose files.
  1. Udpate the docker-compose.yml file of the Pangolin stack to expose metrics port 6060 for the Prometheus connection:
service:
  crowdsec:
    ports:
      - 6060:6060
Docker’s NAT-based port publishing feature automatically exposes all ports: defined in the docker-compose file on all network interfaces. This behavior can bypass your host firewall settings, potentially exposing services that you did not intend to make public. Please see complete warning about exposing ports.
  1. Restart the Crowdsec container to apply the changes:
sudo docker restart crowdsec

​
Prometheus

  1. Create a new Prometheus container or add it to docker-compose.yml of Pangolin stack:
services:
  prometheus:
    container_name: prometheus
    image: prom/prometheus:latest
    restart: unless-stopped
    ports:
      - 9090:9090
    volumes:
      - /etc/timezone:/etc/timezone:ro
      - /etc/localtime:/etc/localtime:ro
      - ./config/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml
      - ./config/prometheus/data:/prometheus
Docker’s NAT-based port publishing feature automatically exposes all ports: defined in the docker-compose file on all network interfaces. This behavior can bypass your host firewall settings, potentially exposing services that you did not intend to make public. Please see complete warning about exposing ports.
  1. Create a prometheus.yml file in the /config/prometheus directory with the following content:
global:
  scrape_interval: 15s
  evaluation_interval: 15s

scrape_configs:
  - job_name: "prometheus"
    static_configs:
      - targets: ["localhost:9090"]

  - job_name: traefik
    static_configs:
      - targets: ["172.17.0.1:8082"]

  - job_name: crowdsec
    static_configs:
      - targets: ["172.17.0.1:6060"]
  1. Create a folder data in /config/prometheus and change the ower and owning group:
chown nobody:nogroup data
  1. Start the Prometheus container:
sudo docker conpose up -d

​
Grafana

  1. Create a new Grafana container or add it to docker-compose.yml of Pangolin stack:
services:
  grafana:
    image: grafana/grafana:latest
    container_name: grafana
    restart: unless-stopped
    ports:
      - 3000:3000
    volumes:
      - /etc/timezone:/etc/timezone:ro
      - /etc/localtime:/etc/localtime:ro
      - ./config/grafana/data:/var/lib/grafana
Docker’s NAT-based port publishing feature automatically exposes all ports: defined in the docker-compose file on all network interfaces. This behavior can bypass your host firewall settings, potentially exposing services that you did not intend to make public. Please see complete warning about exposing ports.
  1. Start the Grafana container:
sudo docker compose up -d
Default login credentials for Grafana admin user is admin:admin.

​
Add Prometheus Connection

Add the Prometheus connection under Connections -> Add new connection. Set http://172.17.0.1:9090 as Prometheus Server URL and click Save & test.

​
Add Dashboard

Add a Dashboard under Dashboard -> New -> Import and import a pre configured Dashboard or create your own.
