ACS supports the cluster inspection feature provided by Container Intelligent Service (CIS). Use this feature to scan your cluster for potential risks, such as insufficient cloud resource quotas and high utilization of key Kubernetes cluster resources. You can then investigate identified risks and follow the recommended solutions to resolve them. This topic describes how to use this feature.
Prerequisites
-
You have created an ACS cluster.
-
The cluster is in the Running state.
Log on to the ACS console. On the Clusters page, find the target cluster. If the value in the Cluster Status column is Running, the cluster is running properly.
Configure cluster inspection
When you use the cluster inspection feature, the system runs a data collection program in your cluster to collect inspection data. This information includes the system version, load, the status of container components, and key error messages from system logs. The program does not collect your business information or sensitive data.
-
Log on to the ACS console. In the left navigation pane, click Clusters.
-
On the Clusters page, click the name of the target cluster. In the left navigation pane, choose Inspections and Diagnostics > Cluster Inspections.
-
On the Cluster Inspections page, in the Schedule Rule section, click Add.
-
In the Configure Scheduled Inspection Rule panel, set the Time Zone and Schedule. After you review the settings, select I have read and agree, and then click Save Configuration.
Once configured, the inspection runs at the specified time.
You can also run an inspection manually. On the Cluster Inspections page, in the Reports section, click Run Cluster Inspection. After the inspection is complete, the report appears in the list.

Cluster inspection helps you proactively identify potential issues through periodic checks. When an inspection finds an anomaly, cluster diagnostics can analyze, locate, and resolve the problem. For more information, see Use cluster diagnostics.
