public class DimensionalReporter extends com.codahale.metrics.ScheduledReporter
Class that allows using a ScheduledReporter to report V2 task metrics with support for dimensions.

This reporter will be started and scheduled with the MetricRegistry. Once it is called on to report, it will query the StormMetricRegistry for various sets of task metrics with unique dimensions. The underlying ScheduledReporter will perform the actual reporting with the help of a DimensionHandler to deal with the dimensions.
