Service Health
Service health is a way to detect unhealthy instances by collecting access statistics. Only instances that pass health checks can be registered with a service mesh.

AOM must be enabled for service meshes. If AOM is not enabled, the service health cannot be checked.

- Click the name of the target service mesh to go to its details page.

- Click the service name and then click the tab for displaying service health.
- Click the tabs for displaying the error rate, request latency, and throughput. You can select different time granularities to view the metrics. You can also determine whether to enable Auto Refresh as required.
