How-To Guides

Step-by-step recipes for connecting external systems to Cardinal, wiring up collectors, and operating around common gotchas. Each guide is destination-agnostic where possible — pick the exporter that fits your downstream.

Available guides

• Polling OpenShift Prometheus metrics from outside the cluster — pull selected prometheus-k8s metrics through the OpenShift federate Route into an external collector.
• Collecting PostgreSQL metrics with postgres_exporter — scrape a PostgreSQL StatefulSet from an in-cluster OpenTelemetry Collector.
