Run the exporter

Modify the FRIGATE_STATS_URL environment variable below to point to your Frigate API stats (replace <your-frigate-ip> with your Frigate docker container IP address). Then run the container:

docker run \
    -d \
    --restart unless-stopped \
    -p 9100:9100 \
    -e "FRIGATE_STATS_URL=http://<your-frigate-ip>:5000/api/stats" \
    --name prometheus_frigate_exporter \
    rhysbailey/prometheus-frigate-exporter

Metrics are available at http://localhost:9100/metrics

Setup Prometheus

If you don't already have Prometheus set up to scrape the prometheus-frigate-exporter metrics,

• create Prometheus config file prometheus.yml

• copy example below into prometheus.yml, replacing <your-prometheus-frigate-exporter-ip> with the IP address of your prometheus_frigate_exporter docker container. <your-prometheus-frigate-exporter-ip> is likely the same IP address as your Frigate docker containers <your-frigate-ip> if running in the same docker instance

  # 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: "prometheus_frigate_exporter"
      static_configs:
        - targets: [
                      "<your-prometheus-frigate-exporter-ip>:9100"
                   ]
  

• 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 Frigate exporter, go to Prometheus targets page http://:9090/targets and look for UP for prometheus_frigate_exporter job.

Setup Grafana

If you don't already have Grafana set up,

• run Grafana

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

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

• Go to http://:3000/datasources

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

• Go to http://:3000/dashboards

  • New -> Import
  • Enter in Import via grafana.com: 18226 (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 Frigate time series metrics in the Grafana dashboard
