Service Mesh (ASM) allows you to diagnose ASM instances for potential risks. The check items include the versions of data-plane components, service ports, associated services, labels of applications and versions, destination addresses, and virtual service conflicts. This feature helps you manage communication between services, detect potential issues in a timely manner, and improve service reliability, performance, and security. This topic describes how to diagnose ASM instances.
Procedure
Log on to the ASM console. In the left-side navigation pane, choose .
On the Mesh Management page, click the name of the ASM instance. In the left-side navigation pane, choose .
Perform the following operations based on the version of your ASM instance:
For a version earlier than V1.17.2.10: On the Mesh Diagnosis page, click Run.
For V1.17.2.10 and later: On the Mesh Diagnosis page, deselect the namespaces that you do not want to diagnose and click Run.
NoteNo diagnosis results will be generated for the deselected namespaces.
If the ASM instance has been diagnosed before, the Mesh Diagnosis page shows the results of the last diagnosis. You can click Run to diagnose the ASM instance again.
The diagnosis results are displayed in the Diagnosis results section. If any unexpected diagnosis results appear, you can follow the suggestions in the Details column to handle them. You can also click Obtain Intelligent Diagnostics Suggestions in the Details column to obtain more detailed diagnosis suggestions generated by ASM AI Diagnostics Assistant (alpha).
