I created a cluster with kubeadm, the k8s version is 1.16.4. And I installed kube-prometheus. But I can not find APIServiceRegistrationController metrics in prometheus.
APIServiceRegistrationController_adds
APIServiceRegistrationController_depth
APIServiceRegistrationController_queue_latency
APIServiceRegistrationController_queue_latency_count
APIServiceRegistrationController_queue_latency_sum
APIServiceRegistrationController_retries
APIServiceRegistrationController_duration
APIServiceRegistrationController_duration_count
APIServiceRegistrationController_duration_sum
