Zebra Metrics

Zebra has support for Prometheus, configured using the MetricsSection.

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

  1. Install 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 locahost:9090.

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

In zebrad.toml:

endpoint_addr = ""

In the grafana dashboard:

  1. Create a new Prometheus Data Source Prometheus-Zebra
  2. Enter the HTTP URL:
  3. Save the configuration

Now you can add the grafana dashboards from zebra/grafana, or create your own.
