rabbitmqctl – RabbitMQ queue size based on the client or country in my case

I am new to RabbitMQ, I am in the process of exploring the rabbitmq cmd line and I am stuck in a place where I need some suggestions.

If I am managing 4000-odd queues and each client has 30-odd queues, all with standard naming conventions.

<country>-<type>-<prioirty>_vl
<country>-<type>-<prioirty>_res
.
.
<country>-<type>-<prioirty>_out

rabbitmqctl list_queues

rabbitmqctl command above lists all the 400 odd queues on the server. I would like to know if I can fetch the queue size based on the country size. Are there any parameters we can use to retrieve data for one client or country at a time?

I tried to check with different arguments and dint find anything conclusive.
