Container Service for Kubernetes:View cluster information

Last Updated:Oct 25, 2024

You can view information about Container Service for Kubernetes (ACK) clusters on the cluster information page, including the basic cluster information, cluster inspection information, relevant cloud resources, and cluster resource monitoring data. This topic describes how to view cluster information and introduces the information displayed on each tab.

Procedure

  1. Log on to the ACK console. In the left-side navigation pane, click Clusters.

  2. On the Clusters page, find the cluster that you want to manage and click its name. In the left-side pane, click Cluster Information.

  3. Click a tab to view the corresponding information.

    For more information, see Cluster information.

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 have occurred in applications.

  • Node Status: This section displays a chart that shows the status of the nodes in the cluster.

  • Cluster Risk Report: This section displays the potential risks that are detected during cluster scans and provides suggestions on how to mitigate the risks. You can create inspection rules to configure the inspection interval and cycle.

  • Events: This section displays cluster events, such as warnings and errors.

  • Monitoring: This section displays the charts for CPU and memory utilization. The CPU utilization is measured in cores and is accurate to three decimal places. The smallest unit is millicores. A millicore is one-thousandth of a core. The memory utilization is measured in GiB and is accurate to three decimal places. For more information, see Meaning of CPU and Meaning of memory.

Security Overview

Click the Security Overview tab to view the cluster security inspection results, including node vulnerabilities, container image risks, and container runtime risks. This helps you learn the potential risks in application configurations.

An inspection report is generated after a security inspection is performed. The report includes the description of each inspection item and suggestions on how to fix the related security issues. You can also configure periodic inspections. The results of each periodic inspection are logged to the specified Logstore in Simple Log Service. For more information, see Use the inspection feature to detect security risks in the workloads of an ACK cluster.

Only ACK Pro clusters support this feature. To use this feature, submit a ticket to apply to be added to the whitelist.

Basic Information

  • Basic Information: This section displays basic information about the cluster, such as cluster ID, region, time zone of the cluster, Kubernetes version, and the status of deletion protection.

  • Network: This section displays network information, such as network plug-in, vSwitch, endpoints of the API server, and Service CIDR block.

  • Security and Auditing: This section displays security and auditing information, such as secret encryption and the status of audit logs.

  • Cluster Resources: This section displays resources used by the cluster, such as Resource Orchestration Service (ROS) stack and log service project.

  • Tag Group: This section displays the resource group and labels of the cluster.

Connection Information

You can obtain the kubeconfig file that can be used to connect a kubectl client to the cluster over the Internet or internal network.

Cluster Monitoring

ACK 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 Monitoring management.

Costs

After you enable the cost insights feature, you can gain insights into the cost and resource usage of a specified cluster, department, or application within a specified financial governance cycle. This meets the requirements for cost estimation, allocation, and accounting in various scenarios. For more information, see Overview of cost insights.

Cluster Logs

You can view cluster logs.

Cluster Tasks

You can view information about cluster tasks, including the task status, associated resources, and start time and end time of each task. Error information is displayed for failed tasks to help you troubleshoot issues.

O&M Tasks

You can query the automated operation and maintenance (O&M) schedules of a cluster, such as automatic kubelet update and auto Common Vulnerabilities and Exposures (CVE) patching. Additionally, you can configure the settings for managed node pools to utilize their automated O&M capabilities. For more information, see Overview of managed node pools.
