Those log lines come from Celery’s startup logging; they show some built‑in tasks (group, xmap, backend_cleanup) being registered and are safe to hide.stackoverflow+1
If you just want Celery to shut up, start your worker with a higher log level, for example:
bash
celery -A your_project worker -l WARNING
or in celery.py / settings, set:
python
worker_hijack_root_logger = False
and then configure your own logging (so you don’t log at INFO for Celery’s root logger).celeryq+1
If you’re using Django and django-celery, make sure your Django logging config either:
sets Celery loggers to WARNING or above, or
disables propagation for celery loggers so those startup messages are not printed.
