Zebra Metrics

Zebra has support for Prometheus, configured using the MetricsSection.

This requires supporting infrastructure to collect and visualize metrics, for example:

  1. Create the zebrad.toml file with the following contents:

    [metrics]
    endpoint_addr = "127.0.0.1:9999"
    
  2. Run Zebra, and specify the path to the zebrad.toml file, for example:

    zebrad -c zebrad.toml start
    
  3. Install and run Prometheus and Grafana via Docker:

    # create a storage volume for grafana (once)
    sudo docker volume create grafana-storage
    # create a storage volume for prometheus (once)
    sudo docker volume create prometheus-storage
    
    # run prometheus with the included config
    sudo docker run --detach --network host --volume prometheus-storage:/prometheus --volume /path/to/zebra/prometheus.yaml:/etc/prometheus/prometheus.yml  prom/prometheus
    
    # run grafana
    sudo docker run --detach --network host --env GF_SERVER_HTTP_PORT=3030 --env GF_SERVER_HTTP_ADDR=localhost --volume grafana-storage:/var/lib/grafana grafana/grafana
    

    Now the grafana dashboard is available at http://localhost:3030 ; the default username and password is admin/admin. Prometheus scrapes Zebra on localhost:9999, and provides the results on localhost:9090.

  4. Configure Grafana with a Prometheus HTTP Data Source, using Zebra's metrics.endpoint_addr.

    In the grafana dashboard:

    1. Create a new Prometheus Data Source Prometheus-Zebra
    2. Enter the HTTP URL: 127.0.0.1:9090
    3. Save the configuration
  5. Now you can add the grafana dashboards from zebra/grafana (Create > Import > Upload JSON File), or create your own.
