Package com.wavefront.agent.logsharvesting

Class EvictingMetricsRegistry

java.lang.Object

com.wavefront.agent.logsharvesting.EvictingMetricsRegistry

public class EvictingMetricsRegistry
extends Object

Wrapper for a Yammer MetricsRegistry, but has extra features regarding automatic removal of metrics. With the introduction of Delta Counter for Yammer metrics, this class now treats Counters as Delta Counters. So anybody using this getCounter(MetricName, MetricMatcher) method will get an instance of Delta counter.
