Interface MetricsRegionSource

All Superinterfaces:

Comparable<MetricsRegionSource>

All Known Implementing Classes:

MetricsRegionSourceImpl

public interface MetricsRegionSource
extends Comparable<MetricsRegionSource>

This interface will be implemented to allow single regions to push metrics into MetricsRegionAggregateSource that will in turn push data to the Hadoop metrics system.
