Cluster inspection, provided by Container Intelligence Service (CIS), scans your ACK cluster for potential risks—including remaining cloud resource quotas and key resource levels—and suggests solutions for each identified issue.
Usage notes
-
Inspection results are retained for 7 days. Results older than 7 days are no longer available.
-
When an inspection runs, ACK executes a data collection program in the cluster. The program collects key error messages from the system log and operation information such as the system version, loads, Docker, and kubelet. It does not collect business data or sensitive information.
Prerequisites
Before you begin, ensure that you have:
-
A cluster in Running state. Confirm this on the Clusters page of the ACK console
Set up a scheduled inspection
-
Log on to the ACK console. In the left-side navigation pane, click Clusters.
-
On the Clusters page, find the target cluster and click its name. In the left-side pane, choose Inspections and Diagnostics > Cluster Inspections.
-
In the Schedule Rule section of the Cluster Inspection page, click Add.
-
In the Set Inspection Rule pane, set TimeZone and Regular Task Rule (Daily), confirm the cluster information, read the warning message, and save the configuration. After you save the configuration, ACK inspects the cluster daily at the scheduled time. To run an inspection immediately, click Start in the Reports section. The results appear in the Reports section after the inspection completes.
View inspection results
In the Reports section of the Cluster Inspection page, click Details in the Operation column of the report.
The report lists all identified risks ordered by severity from lowest to highest: Warning, Error, and Critical. Critical-level risks are highlighted. For each risk, the report shows its severity level, potential impact, and recommended solution. Follow the guidance in the console to resolve the issues.
