Hey, I'm one of the co-founders of Opsee. Part of our beta is collecting enough data to figure out a reasonable pricing structure. We're leaning pretty heavily towards charging based on the number of health checks you have setup, independent of the number of instances you're checking. So it'll be much closer to how pingdom does pricing than a new relic, for instance.
Exactly, and with a containerized infrastructure the per host pricing model breaks down further. Our goal is to have the most frictionless pricing model for people with a microservice architecture.
Just to be clear: we (New Relic) explicitly state on our pricing page that we do NOT charge for containers. It's in our FAQ. We view them as processes, not hosts.
