java.lang.Objectorg.apache.activemq.apollo.dto.QueueMetricsDTO
public class QueueMetricsDTO
Collects metrics about the status of a queue since the time a broker gets started.
Note that you may need to do a little math to compute how much the number of message swapped on disk: swapped_out_size = queue_size - swapped_in_size
