Observability

Gather metrics for your GraphQL APIs in Prometheus and Grafana.

Access Envoy logs in Prometheus and Grafana

Review the Gloo Edge Observability documentation to access the default Prometheus and Grafana deployments that are installed with Gloo Edge, or configure your own Prometheus or Grafana instances.

For example, you can use the following commands to access the Envoy pod logs in the default Prometheus and Grafana dashboards:

• Prometheus:

  kubectl -n gloo-system port-forward deployment/gateway-proxy 19000
  
  curl http://localhost:19000/stats/prometheus
  

• Grafana:

  kubectl -n gloo-system port-forward deployment/glooe-grafana 3000
  
  open http://localhost:3000/
  

Envoy metrics for GraphQL

The following Envoy metrics are collected for GraphQL APIs in your Gloo Edge environment. The metric includes the name of your GraphQL API resource with hyphens replaced by underscores, such as <api_name> in the following example.
