Service Mesh (ASM) supports Mesh Diagnosis for instances. This feature checks for common issues, including the data plane version, service ports, service associations, app and version labels, destination addresses, and virtual service conflicts. Mesh Diagnosis helps you better manage inter-service communication, promptly identify potential issues, and improve the reliability, performance, and security of your services.
