If we are to mention specific services, I think it behooves us to at least mention all of the pike supported metric services and specifically the names/units determined by those services.  Until we remove ceilometer support entirely from watcher our grammar won’t know what is used as the metrics.  Metric service support will really be enforced by the strategies.
