The setup is currently this: Kubernetes is deployed on AWS instances within a private hosted zone on AWS (only vpn access to the instances, though there is a NAT gatway), with Prometheus deployed as a stateful set within kubernetes to monitor health.
The question is, how do I set it up so I get an alert of Prometheus itself were actually to go down? I thought about trying to use a route 53 health check, but it appears that only works with public addresses.
