/**
 * A StatisticsBrokerPlugin
 * You can retrieve a Map Message for a Destination - or
 * Broker containing statistics as key-value pairs The message must contain a
 * replyTo Destination - else its ignored
 * To retrieve stats on the broker send a empty message to ActiveMQ.Statistics.Broker (Queue or Topic)
 * With a replyTo set to the destination you want the stats returned to.
 * To retrieve stats for a destination - e.g. foo - send an empty message to ActiveMQ.Statistics.Destination.foo
 * - this works with wildcards to - you get a message for each wildcard match on the replyTo destination.
 * The stats message is a MapMessage populated with statistics for the target
 * @org.apache.xbean.XBean element="statisticsBrokerPlugin"
