How to Monitor kube-controller-manager

Kube-controller-manager is a crucial component of Kubernetes' control plane, responsible for ensuring the desired state of Kubernetes objects by using a watch mechanism to communicate with the Kubernetes API. It includes various controllers such as ReplicaSet, Deployment, Namespace, ServiceAccount, Endpoint, and PersistentVolume controllers, each managing specific tasks to maintain or adjust the system state. Monitoring the kube-controller-manager is essential to prevent disruptions in the creation and management of Pods and other Kubernetes objects, with Prometheus being a common tool used for scraping and analyzing relevant metrics such as workqueue duration, client request rates, and resource usage statistics. Accessing these metrics might require configuration adjustments, especially concerning the bind-address settings, to ensure that Prometheus can effectively gather data from the kube-controller-manager. Sysdig Monitor offers an integrated solution for monitoring and troubleshooting Kubernetes clusters, potentially accelerating issue resolution by up to ten times, with built-in dashboards and tools like Advisor designed to streamline the process.
