Tasks

Tasks that run in the background, like Metadata Batch Updates can be seen on the Tasks list

Each task can be inspected and can be rerun on some Items if they have failed.

Background Tasks

To help monitoring the system we have Flower as part of the Background Tasks monitoring, that monitors all Celery tasks in the system.

More information about how Flower works can be found at http://flower.readthedocs.io/en/latest/
