  2. For the sake of this workshop, let us create some traffic to the echo-api. Run the following command on the upper terminal. You will see a combination of 403 and 429 errors in the terminal.

    for i in {1..1000}; do curl -k -w "%{http_code}" https://echo.travels.{ocp_cluster_workshop_main_domain}; done

  3. Access the Grafana dashboard tab again, and click the refresh button as shown in the screenshot below.

    You may need to refresh a couple of times for the metrics to appear in the Grafana dashboard.

    Notice that 429 and 403 requests, as well as the total requests, are available in the different sections of the dashboard.

    1. View Gateway, HTTPRoute, and its policies

      Don’t see the HTTPRoute’s policies? You might need to restart the kube-state-metrics pod.

      • Run this command in the top-right terminal to nudge the metrics a bit.

        oc rollout restart deployment/kube-state-metrics-kuadrant -n monitoring

      • Refresh the dashboard using the refresh button on top-right of the browser, and voila, everything is alright in our dashboard world.

    2. View details of Total requests, latency, and CPU and memory usage

  5. Finally, click the Business User Dashboard link at the top left of the page. This dashboard shows data such as traffic summary and historical request comparison, which are more relevant to business users.
