You can't know if *a* customer can access the service it provides. You
can know if the service access point is up and connected to the server

Take a simple example of shared-nothing read-only cluster: all you need
to know is that the daemon is bound to '*' and the floating ip is bound
to eth0.

This is the "best" in that it's simple, stupid, does all you you
need/can do and nothing that doesn't make your cluster run any "better".
 It's also very unexciting.
