+#### Meter
+
+A `Meter` measures an average throughput. An occurrence of an event can be
registered with the `markEvent()` method. Occurrence of multiple events at the
same time can be registered with `markEvent(long n)` method.
+You can register a meter by calling `meter(String name, Meter histogram)`
on a `MetricGroup`.
