EDIT: See other answers for getting a list of tasks in the queue. RabbitMQ is a message broker widely used with Celery.In this tutorial, we are going to have an introduction to basic concepts of Celery with RabbitMQ and then set up Celery for a small demo project. The worker name defaults to [email protected] a container environment, hostname is the container hostname. Flower uses github-style syntax for args/kwargs/result filtering. Google OAuth 2.0 authentication is enabled using the –auth, –oauth2_key, –oauth2_secret and –oauth2_redirect_uri options. The Flower dashboard lists all Celery workers connected to the message broker. The RabbitMQ, Redis transports are feature complete, but there’s also experimental support for a myriad of other solutions, including using SQLite for local development. Flower provides a few different authentication mechanisms to control access to the Celery metrics. You should look here: Celery Guide - Inspecting Workers Basically this: from celery.app.control import Inspect # Inspect all nodes. For what it’s worth, the container hostname is a meaningless string. Celery Worker on Docker. celery==4.2.1 billiard==3.5.0.5 kombu==4.2.1 eventlet==0.23.0 gevent==1.3.7. Google OAuth 2.0¶. Scripts work with no change to installed libs using above set of lib/versions. An advanced flow management above Celery (an asynchronous distributed task queue) written in Python3, that allows you to: Dynamically schedule tasks based on results of previous tasks Group tasks into flows in simple YAML configuration files Prometheus integration. However in production, while flower reflects actual state of workers, clicking worker name in flower does not return worker states (equivalent to celery ... inspect active) after some time. Celery can run on a single machine, on multiple machines, or even across datacenters. It can be used for anything that needs to be run asynchronously. Celery assigns the worker name. Basic Auth, Google, Github, Gitlab and Okta OAuth. Flower is a great tool for monitoring Celery processes but sadly cannot be deployed in the same instance as your primary Heroku application.A simple solution is to run Flower on a seperate Heroku instance. Celery is an asynchronous task queue. I am using GitHub OAuth, with the required OAuth parameters being passed into the process via environment variables. This simple project will launch Flower with Redis to monitor your Celery processes from another project. Celery is usually used with a message broker to send and receive messages. Being the recommended monitor for Celery, it obsoletes the Django-Admin monitor, celerymon and the ncurses based monitor. This way you can authenticate any user with a Google account.
