AKS cluster control plane metrics in managed Prometheus is a new feature that automatically scrapes the control plane – API server and etcd metrics and send them to a Azure Monitor workspace via managed Prometheus. With this, you are able monitor the API server traffic and load along with the etcd size, object count to understand the state of the control plane and tune Kubernetes application client behavior to optimize for performance and reliability. AKS clusters with managed Prometheus get these new metrics automatically once the subscription has been enabled for the preview feature.
