Answer 1

The error message actually says it all:

"Error: Broadcast not supported by SQL broker transport".

From Celery 3.1 documentation,

Limitations

The Django database transport does not currently support:

• Remote control commands (celery events command, broadcast)
• Events, including the Django Admin monitor.
• Using more than a few workers (can lead to messages being executed multiple times).

status is one of the monitoring commands.
