Returns:

an object that will be sent sent to IMetricsConsumer#handleDataPoints(org.apache.storm.metric.api.IMetricsConsumer .TaskInfo, java.util.Collection). If null is returned nothing will be sent. If this value can be reset, like with a counter, a side effect of calling this should be that the value is reset.
