Celery: Can't inspect SQS workers

[fbm]

I'm trying to inspect running workers using:
$ celery -A firstapp.mycelery inspect active

If backend is RabbitMQ
=> Celery returns running workers
If backend is SQS
=> Celery returns "Error: No nodes replied within time constraint."

Package list:

• amqp (1.4.9)
• anyjson (0.3.3)
• billiard (3.3.0.23)
• boto (2.40.0)
• celery (3.1.23)
• contextlib2 (0.5.3)
• kombu (3.0.35)
• pip (1.5.6)
• pytz (2016.4)
• raven (5.15.0)
• setuptools (3.6)
• wsgiref (0.1.2)

As described in the docs

SQS does not yet support worker remote control commands

I also had hard time until find this information. Basically you can't inspect the state of any woker in the cluster.
You can keep a eye on CloudWatch or use Redis/Elasticache as broken which has monitoring support.

Yeah, SQS doesn't support broadcast and as far as I know no support for that is planned either :(

Perhaps it would be also good to set CELERY_ENABLE_REMOTE_CONTROL to False when using SQS so you prevent celery from creating useless queues.
