Detect whether Celery is Available/Running

Question

I\'m using Celery to manage asynchronous tasks. Occasionally, however, the celery process goes down which causes none of the tasks to get executed. I would like to be able t

Answer 1

One method to test if any worker is responding is to send out a 'ping' broadcast and return with a successful result on the first response.

from .celery import app  # the celery 'app' created in your project

def is_celery_working():
    result = app.control.broadcast('ping', reply=True, limit=1)
    return bool(result)  # True if at least one result

This broadcasts a 'ping' and will wait up to one second for responses. As soon as the first response comes in, it will return a result. If you want a False result faster, you can add a timeout argument to reduce how long it waits before giving up.
