One option not requiring a monitoring thread is a Celery on_success handler (using bootsteps feature in 3.1+) - this would need to write relevant info to your own datastore.

Possibly better option, needing less code, is to use a task_success signal in a similar way, recording the info you need later.

The Flower option is probably simpler, as you are querying info already maintained by Flower when tasks complete - see this answer.
