Celery: Can't inspect SQS workers

Created on 6 May 2016  ·  3Comments  ·  Source: celery/celery

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)

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.

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 :(
