Incorrect metrics in latest snapshot
------------------------------------

                 Key: APLO-170
                 URL: https://issues.apache.org/jira/browse/APLO-170
             Project: ActiveMQ Apollo
          Issue Type: Bug
         Environment: Apollo 99-trunk-20120306.040517-2
            Reporter: Lionel Cons


After running a stress test (with stomp-benchmark) on the latest Apollo snapshot, we get incorrect
metrics via the REST API.

Most queues are empty but we get for /dest-metrics:

{
  'consumer_count' => 2,
  'consumer_counter' => 3747,
  'current_time' => '1331811113155',
  'dequeue_item_counter' => 1308687850,
  'dequeue_size_counter' => '1676664197980',
  'dequeue_ts' => '1331811112533',
  'enqueue_item_counter' => 2903640770,
  'enqueue_size_counter' => '2557292455212',
  'enqueue_ts' => '1331811113155',
  'expired_item_counter' => 0,
  'expired_size_counter' => 0,
  'expired_ts' => '1331811094462',
  'nack_item_counter' => 219021,
  'nack_size_counter' => 86391291,
  'nack_ts' => '1331811094462',
  'objects' => 12,
  'producer_count' => 77,
  'producer_counter' => 4838,
  'queue_items' => 280614806,
  'queue_size' => '236922566764',
  'swap_in_item_counter' => 326917022,
  'swap_in_size_counter' => '345397442494',
  'swap_out_item_counter' => 610143466,
  'swap_out_size_counter' => '583772449904',
  'swapped_in_items' => 163303,
  'swapped_in_size' => 88326399,
  'swapped_in_size_max' => 819200000,
  'swapping_in_size' => 1752840,
  'swapping_out_size' => 1310961,
}

Note that queue_size=236922566764, so rough;y 220GB. OTOH, we see:

9.4G	data/
