Summary:                    "queue show" shows old (cached) information, whilst
"queue show QUEUENAME" shows current information when using realtime.
Description: 
Whenever 'queue show' is used, realtime is not queried for any updates.
When 'queue show QUEUENAME' is used, it is.

This is defined in apps/app_queue.c:

/* We only want to load realtime queues when a specific queue is asked
for. */
if (argc == 3)  /* specific queue */
   load_realtime_queue(argv[2]);

I appreciate that this has been deliberately coded this way, but in my
opinion, this is erroneous behaviour.

If realtime information is not loaded for each queue, then the output of
'queue show' is just plain wrong and can't be relied on - the command
simply becomes useless.

The response to bug http://bugs.digium.com/view.php?id=0012556 was that the AMI
should be used to collect
status information. At the moment, one must be aware of each queue name in
order to retrieve status information for it - The problem is that third
party applications cannot report on the status of queues using the AMI
without having this knowledge (i.e. access to the realtime data store). In
addition, even if they were aware of this, they would have to make one
'queue show QUEUENAME' call for each of the queues they require information
on - this is clearly inefficient at best.

I believe that the fact that 'queue show' returns incorrect information
should be considered a bug.

Here's a patch that will make "queue show" retrieve realtime queue
information even if no queue is specified.
