Description

Support Exposing AMS High Availability (HA) Status

Use case/motivation

I hope to obtain the master-slave status of AMS through HTTP and metrics.

Describe the solution

We can introduce a member variable to identify the master/slave status of the AMS. The HTTP interface and metrics can then use this field to retrieve the AMS's master/slave status.
