Celery: how to get a list of tasks waiting for their turn to be executed?

Question

Python

Colleagues, tell me how to get a list of tasks waiting for their turn to be executed?
Tasks that are currently running can be found next. way:

from celery.task.control import inspect
i = inspect()
i.active()

Judging by the documentation , the tasks waiting for their turn should be returned by the i.scheduled() function, but it returns an empty array:

from celery.task.control import inspect
i = inspect()
i.scheduled() # => {u'[email protected]': []}

Answer 1

Reserved tasks are tasks that has been received, but is still waiting to be executed.
scheduled are tasks with deferred execution
