This section describes how to view the cluster status overview.

Prerequisites

  • You need to join a cluster and have the Monitoring View permission in the cluster. For more information, see Cluster Members and Cluster Roles.

  • The WizTelemetry Monitoring extension must be installed and enabled on the KubeSphere platform.

Steps

  1. Log in to the KubeSphere web console with a user who has Monitoring View permissions and enter your cluster.

  2. Click Monitoring and Alerting > Cluster Monitoring in the left navigation pane.

  3. On the Cluster Monitoring page, under the Overview tab, view the status of cluster nodes, cluster resources, etcd, and service components.
