Project description

Flower is a web based tool for monitoring and administrating Celery clusters.


  • Shutdown or restart workers
  • View workers status (completed, running tasks, etc.)
  • View worker pool options (timeouts, processes, etc.)
  • Control worker pool size
  • View message broker options
  • View active queues, add or cancel queues
  • View processed task stats by type
  • View currently running tasks
  • View scheduled tasks
  • View reserved and revoked tasks
  • Apply time and rate limits
  • View all active configuration options
  • View all tasks (by type, by worker, etc.)
  • View all task options (arguments, start time, runtime, etc.)
  • Revoke or terminate tasks

Flower API enables to control the cluster via REST api and receive task events in real-time via WebSockets.

For example you can restart worker’s pool by:

$ curl -X POST http://localhost:5555/api/worker/pool/restart/myworker

Or terminate executing task by:

$ curl -X POST -d '{"terminate":True}' http://localhost:5555/api/task/revoke/8a4da87b-e12b-4547-b89a-e92e4d1f8efd

Or receive task completion events in real-time:

var ws = new WebSocket('ws://localhost:5555/api/task/events/task-succeeded/');
ws.onmessage = function (event) {


To install, simply:

$ pip install flower


Launch the server and open http://localhost:5555:

$ flower --port=5555

Or launch from celery:

$ celery flower --port=5555
