So basically doctor wants to know state of Cinder services as soon as
possible, right? Why use cinder to inform of its own services then? What
if cinder-api service is down?

If your use case is monitoring of services state, then what prevents you
from using some external monitoring tools for that purpose? Or even a
combination of both external monitoring tool and Cinder service-group API?
