How to inspect and cancel Celery tasks by task name

Question

I\'m using Celery (3.0.15) with Redis as a broker.

Is there a straightforward way to query the number of tasks with a given name that exist in a Celery queue?

Answer 1

# Retrieve tasks
# Reference: http://docs.celeryproject.org/en/latest/reference/celery.events.state.html
query = celery.events.state.tasks_by_type(your_task_name)

# Kill tasks
# Reference: http://docs.celeryproject.org/en/latest/userguide/workers.html#revoking-tasks
for uuid, task in query:
    celery.control.revoke(uuid, terminate=True)
