我用kubeadm创建了一个集群，k8s版本是1.16.4。然后我安装了kube-prometheus。 但是我在普罗米修斯找不到APIServiceRegistrationController指标。
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
