kube-state-metrics (KSM) monitors and generates metrics about the state of the Kubernetes objects. KSM monitors the health of various Kubernetes objects such as Deployments, Nodes, and Pods. For more information, see kube-state-metrics (KSM) from GitHub. You can use the kube-state-metrics-based modules available in LM Exchange in conjunction with the new LM Container Helm charts to gain better visibility of … Continued
etdc is a lightweight, highly available key-value store where Kubernetes stores the information about a cluster’s state. For more information, see Operating etcd clusters for Kubernetes from Kubernetes documentation. LogicMonitor can only monitor etcd clusters that are deployed within a Kubernetes Cluster, and not those that are deployed outside of the cluster. Requirements for Monitoring etcd Ensure you … Continued
The Controller Manager are control loops that continuously watch the state of your cluster loop in a Kubernetes cluster. The Controller Manager monitors the current state of your cluster through the API Server and makes appropriate changes to keep the application running by ensuring sufficient Pods are in a healthy state.
