Prometheus Metrics HTTP Server
This code provides the ability to start/stop a native Golang HTTP Server backed by the default Prometheus handler. The desired HTTP Port & Path are specified upon server creation. This should allow the Channel, Controller, and Dispatcher to quickly add this capability in a consistent manner without code duplication.
This code only serves to expose the default Prometheus metrics on a specified port/path. The creation of the K8S Service and Prometheus ServiceMonitor is left up to the individual component to provide.
Metrics Endpoint
In order to manually test the exposed /metrics endpoint you can port forward the service
kubectl port-forward svc/<service> -n <namespace> 8081:8081
...and point your browser at http://localhost:8081/metrics, or you can use telepresence and curl...
telepresence
curl http://<service>.<namespace>.svc.cluster.local:8081/metrics
Prometheus Console
In order to expose the Prometheus console in the Kyma cluster simply expose the port...
kubectl port-forward svc/monitoring-prometheus -n kyma-system 9090:9090
...and then point you browser at http://localhost:9090/graph or http://localhost:9090/targets
