Celery: list all tasks, scheduled, active *and* finished
Update for the bounty
I'd like a solution that does not involve a monitoring thread, if possible.
I know I can view scheduled and active tasks using the Inspect class of my apps Control.
i = myapp.control.inspect()
currently_running = i.active()
scheduled = i.scheduled()
But I could not find any function to show already finished tasks. I know that this information mus be at least temporarily accessible, because I can look up a finished task by its task_id:
>>> r = my task.AsyncResult(task_id=' ... ')
>>> r.state
u'SUCCESS'
How can I get a complete list of scheduled, active and finished tasks? Or possibly a list of all tasks at once?
Answer
Celery Flower shows tasks (active, finished, reserved, etc) in real time. It enables to filter tasks by time, workers and types.
