title: get Activemq Dequeued messages statistic over time
body: <p>I'm trying to monitor activemq Dequeued messages overtime and save them in Zenoss monitoring system. </p>
  
  <p>I can see the Dequeued number in the control panel of activemq, however if I restart activemq, those numbers are reset. </p>
  
  <p>What's the best way of capturing statistics? </p>
  
  <p>Thanks</p>
