[Solved]-Retrieve queue length with Celery (RabbitMQ, Django)

Here is an example on how to read the queue length in rabbitMQ for a given queue:

def get_rabbitmq_queue_length(q):
    from pyrabbit.api import Client
    from pyrabbit.http import HTTPError

    count = 0

    try:
        cl = Client('localhost:15672', 'guest', 'guest')
        if cl.is_alive():
            count = cl.get_queue_depth('/', q)
    except HTTPError as e:
        print "Exception: Could not establish to rabbitmq http api: " + str(e) + " Check for port, proxy, username/pass configuration errors"
        raise

    return count

This is using pyrabbit as previously suggested by Philip

PyRabbit is probably what you are looking for, it is a Python interface to the RabbitMQ management interface API. It will allow you to query for queues and their current message counts.

You can inspect the workers in celery by using inspect module. Here is the guide.

Also for RabbitMQ there are some command line command.
