The OpenTelemetry Collector, when configured with a Prometheus receiver, provides an integration with Kong Ingress to scrape Prometheus metrics. The Collector uses the Prometheus Receiver to fetch metrics from the Kong Ingress endpoint. From there, the metrics are processed and exported to Cloud Observability.

To complete the integration, perform the following steps:

  • Configure Kong Ingress
  • Configure the Collector to use the Kong Ingress endpoint as a scrape target for the Prometheus receiver
  • Enable the integration by adding it to a pipeline


  • Kong Ingress running in a Kubernetes environment.
  • You’ve configured the Collector to export metric data to Cloud Observability.

Configure Kong Ingress reporting

Kong Ingress exposes metrics by using a Prometheus plugin. See the Kong Ingress example for an integration inside a Kubernetes cluster.

Configure the Collector receiver

In the Collector configuration file, specify the Kong Ingress Prometheus endpoint as a scrape target.

        - job_name: otel-kong
            - targets: [kong-metrics:9119]

The OpenTelemetry repository readme provides additional details about Prometheus receiver configuration.

Complete information about the Prometheus scrape configuration can be found in the Prometheus documentation.

Enable the Collector receiver

After the Kong Ingress receiver is configured, enable it by adding it to one or more pipelines as described in the Collector configuration documentation.

Validate metrics are reporting to Cloud Observability

You can validate that metrics are reporting to Cloud Observability on the Metrics details page in Settings.

  1. In Cloud Observability, click Settings > Metric details.

  2. Search for Kong Ingress metric names. Search for metric

    See the Prometheus plugin documentation for a detailed description of provided metrics.

  3. If needed, select the metric to edit the description and how the units are displayed in Cloud Observability.

Create a dashboard for the metrics

Use the Cloud Observability Terraform Provider to create a dashboard for the metrics.
