What are the units for Cinnamon rates?
The units will actually depend on the metric backend used. Rate is a general interface that just has a mark method.
For the Coda Hale Metrics backend, the custom metrics Rate is backed by a Meter. Meters record rates in events per second. These per-second rates are reported as moving averages for 1 minute, 5 minute, and 15 minute windows. And there's also a mean rate for the lifetime of the application.
For the Prometheus backend, the Rate is backed by a monotonic counter.
