View cluster information - Container Compute Service - Alibaba Cloud Documentation Center

You can view information about Alibaba Cloud Container Compute Service (ACS) clusters on the cluster information page, including the cluster inspection information, relevant cloud resources, and cluster resource monitoring data. This topic describes how to view information about a cluster on the cluster information page in the ACS console and introduces the information displayed on each tab on the page.

Prerequisites

An ACS cluster is created.

Procedure

Log on to the ACS console. In the left-side navigation pane, click Clusters.
On the Clusters page, find the cluster that you want to manage and click its name. In the left-side navigation pane of the cluster details page, click Cluster Information.

Click a tab on the Cluster Information page to view the corresponding information.

Tab	Description
Overview	Select a namespace to view the status of applications and components and view resource monitoring data in charts. Application Status: This section displays charts that provide information about the status of Deployments, StatefulSets, and pods in the namespace. The green color indicates that applications are running as expected. The yellow color indicates that errors occurred in applications. Cluster Risk Report: This section displays the potential risks that are detected during cluster scans and provides suggestions on how to mitigate the risks. Events: This section displays cluster events, such as warnings and errors. Monitoring: This section displays the charts for CPU usage and memory usage. CPU usage is measured in cores and is accurate to three decimal places. The smallest unit is millicores. A millicore is one-thousandth of a core. Memory usage is measured in GiB and is accurate to three decimal places. For more information, see Meaning of CPU and Meaning of memory.
Basic Information	Basic Information: This section displays the cluster ID, cluster status, and the region where the cluster resides. Cluster Information: This section displays information such as the endpoints of the API server, Service CIDR block, custom certificate subject alternative names (SANs), and whether RAM Roles for Service Accounts (RRSA) OpenID Connect (OIDC) is enabled. Cluster Maintenance: This section displays information about the cluster maintenance window.
Connection Information	You can obtain the kubeconfig file that is used to connect a kubectl client to the cluster over the Internet or internal network. Note If Access to API Server is not selected when you create the cluster, the kubeconfig file displays only the credentials used to connect to the cluster over the internal network.
Cluster Resources	You can view all Alibaba Cloud resources used by the cluster, including the virtual private cloud (VPC), node vSwitches, security group, and Simple Log Service project used by the cluster. You can also view the Server Load Balancer (SLB) instance used to expose the API server of the cluster. To check a resource in the corresponding console, click the resource ID. Important The resources are managed by ACS. Do not delete or modify the resources in case your cluster and the applications in the cluster cannot work as expected.
Cluster Monitoring	ACS is integrated with Managed Service for Prometheus to allow you to monitor resources in your cluster. You can view the utilization of CPU, memory, and network resources and create alert rules. For more information, see Use Managed Service for Prometheus to monitor ACS clusters.
Cluster Logs	You can view cluster logs.
Task Logs	You can view information about cluster tasks, including the task status, and start time and end time of each task. Error information is displayed for failed tasks to help you troubleshoot issues.
