Please read the manual. rabbitmqctl:
    list_queues [-p <vhostpath>] [<queueinfoitem> ...]

<queueinfoitem> must be a member of the list [name, durable,
auto_delete,  arguments, pid, owner_pid, exclusive_consumer_pid,
exclusive_consumer_tag, messages_ready, messages_unacknowledged,
messages, consumers, memory].

messages_unacknowledged is what you're after. You probably want in
total:

rabbitmqctl list_queues name messages_ready messages_unacknowledged

as "messages" on its own is messages_ready + messages_unacknowledged.
