'rabbitmqctl list_queues' shows queues and their message counts. It 
takes just a little bit of post-processing to produce results like 
"total message count", "top ten queues", "queues with more than X 
messages", etc.

You can certainly get the list of the exchanges ('rabbitmqctl 
list_exchanges'), but no stats. Stats on exchanges would be tricky to 
implement w/o impacting performance - atm they are completely stateless.

'rabbitmqctl list_bindings'

You can get the queue memory with 'rabbitmqctl list_queues', though that 
doesn't necessarily include messages since they may be shared between 
queues. For total Erlang memory usage, the operating system has plenty 
of commands and utilities to give you accurate figures.

These, and a whole bunch of other stats, are on our todo list.
