How to list the queued items in celery?

I have a Django project on an Ubuntu EC2 node, which I have been using to set up an asynchronous using Celery.

Here is a copy-paste solution for Redis:

def get_celery_queue_len(queue_name):
    from yourproject.celery import app as celery_app
    with celery_app.pool.acquire(block=True) as conn:
        return conn.default_channel.client.llen(queue_name)


def get_celery_queue_items(queue_name):
    import base64
    import json
    from yourproject.celery import app as celery_app

    with celery_app.pool.acquire(block=True) as conn:
        tasks = conn.default_channel.client.lrange(queue_name, 0, -1)

    decoded_tasks = []

    for task in tasks:
        j = json.loads(task)
        body = json.loads(base64.b64decode(j['body']))
        decoded_tasks.append(body)

    return decoded_tasks

It works with Django. Just don't forget to change yourproject.celery.

If you want to get all scheduled tasks,

celery inspect scheduled

To find all active queues

celery inspect active_queues

For status

celery inspect stats

For all commands

celery inspect

If you want to get it explicitily.Since you are using redis as queue.Then

redis-cli

>KEYS * #find all keys

Then find out something related to celery

>LLEN KEY # i think it gives length of list
