Exceptions

You can use the exception feature to quickly obtain the health status of a cluster, and perform root cause analysis and locate the cause of the problem when an exception occurs.

Prerequisites

You have completed one-click diagnostics and generated a diagnostic report. If not, please refer to Initiate one-click diagnostics.

Procedure

1. In the Diagnostic Report section, click Exception to view the exceptions of the target object, including Object, Exception Type, Exception Description, Current Status, Occurrence Time, Restore Time, Duration, and Actions.

2. Click Root Cause Analysis in the Actions column of a single exception to view the root cause analysis and optimization suggestions for the exception.

   • If the cause of the exception is in the analysis graph, the system will highlight the cause in red and provide optimization suggestions.

     Note

     In the analysis graph, each node represents an analysis rule. When performing root cause analysis, the system traverses the graph to find the root cause node. The root cause node is highlighted in red, while the green node indicates that the rule does not hit the root cause.

   • If the cause of the exception is not in the analysis graph, the system will provide optimization suggestions in the Solution section.
