Celery flower for several applications

| Comments

If there is a need to monitor several applications, there are two ways:

  • run celery flower instance for each application
celery flower --app app1.celeryapp --port=5555
celery flower --app app2.celeryapp --port=5556
  • run celery flower with broker option, there will be less options to control tasks
celery flower --broker=redis://redis/0

Celery checklist

| Comments

There is a good checklist to build great celery async tasks.

I want only to add how to autoreload celery worker in development mode. Before there was an --autoreload option, but now it’s removed. For this task I use watchdog.

pip install watchdog
watchmedo auto-restart --recursive -d app -p '*.py' -i '*.pyc' -- celery worker --app app.celeryapp --queues my_query -n my_queue@%h --loglevel INFO
