Prometheus CAKE Autorate exporter

This is a Prometheus exporter for CAKE-autorate stats.

GitHub

Grafana Dashboard

Run the exporter on an OpenWRT router

Once CAKE-autorate is running, to setup this exporter

1. Install python3 and python3-pip

opkg update
opkg install python3 python3-pip

2. Install prometheus-client

pip install prometheus-client

3. Download the exporter

cd /root
wget https://raw.githubusercontent.com/bairhys/prometheus-cake-autorate-exporter/main/prometheus_cake_autorate_exporter.py

4. Start exporter manually

python prometheus_cake_autorate_exporter.py

5. Test to determine if metrics accessible. In a browser, try accessing http://192.168.1.1:9101/, should see raw metrics like below

6. Stop running exporter manually (Ctrl+C)

7. Setup service

wget -P /etc/init.d/ https://raw.githubusercontent.com/bairhys/prometheus-cake-autorate-exporter/main/prometheus-node-exporter-cake-autorate
chmod +x /etc/init.d/prometheus-node-exporter-cake-autorate

6. Enable and start service

service prometheus-node-exporter-cake-autorate enable
service prometheus-node-exporter-cake-autorate start

7. Test to determine if metrics accessible as a service. In a browser, try accessing http://192.168.1.1:9101/, should see raw metrics again like above

Setup Prometheus

If you don't already have Prometheus set up to scrape the CAKE Autorate metrics, setup Prometheus to run on your server

• create Prometheus config file prometheus.yml

• copy example below into prometheus.yml, replacing 192.168.1.1:9101 with the IP address and port of your exporter.

  # my global config
  global:
    scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
    evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
    # scrape_timeout is set to the global default (10s).
   
  # A scrape configuration containing exactly one endpoint to scrape:
  # Here it's Prometheus itself.
  scrape_configs:
    # The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
    - job_name: "prometheus"
      static_configs:
        - targets: ["localhost:9090"]
  
    - job_name: 'router_cake_autorate'
      scrape_interval: 3s
      metrics_path: /metrics
      static_configs:
        - targets: ["192.168.1.1:9101"]
  

• Run Prometheus docker container by replacing /path/to/prometheus.yml to point to the prometheus.yml just created

  docker run \
      -d \
      --restart unless-stopped \
      -p 9090:9090 \
      -v /path/to/prometheus.yml:/etc/prometheus/prometheus.yml \
      prom/prometheus

To see if Prometheus is scraping the exporter, go to Prometheus targets page http://your-prometheus-ip:9090/targets and look for UP for router_cake_autorate job.

Setup Grafana

If you don't already have Grafana set up, setup Grafana to run on your server

• run Grafana

  docker run \
      -d \
      --restart unless-stopped \
      -p 3000:3000 \
      grafana/grafana-oss

• Go to Grafana http://your-grafana-ip:3000 (might take a few minutes first run). Use admin:admin to log in

• Go to http://your-grafana-ip:3000/datasources

  • add Prometheus datasource
  • Set Prometheus URL http://<your-prometheus-ip>:9090
  • Click Save and Test to check if connected

• Go to http://your-grafana-ip:3000/dashboards

  • New -> Import
  • Enter in Import via grafana.com: 18597 (id can be found at Grafana Dashboard) and click Load
  • Set the datasource as Prometheus instance set up before then click Import

• Should now be able to see CAKE Autorate time series metrics in the Grafana dashboard
