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:
In the Collector configuration file, specify the Kong Ingress Prometheus endpoint as a scrape target.
1 2 3 4 5 6 7 receivers: prometheus: config: scrape_configs: - job_name: otel-kong static_configs: - 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.
After the Kong Ingress receiver is configured, enable it by adding it to one or more pipelines as described in the Collector configuration documentation.
You can validate that metrics are reporting to Cloud Observability on the Metrics details page in Project settings.
In Cloud Observability, click Project settings > Metric details.
Search for Kong Ingress metric names.
See the Prometheus plugin documentation for a detailed description of provided metrics.
If needed, select the metric to edit the description and how the units are displayed in Cloud Observability.
Use the Cloud Observability Terraform Provider to create a dashboard for the metrics.
