Monitoring Celery

When our code is pushed to the server, our Celery worker will not be run in the terminal window, it will be run as a background task. Because of this, Celery provides many command-line arguments to monitor the status of your Celery worker and tasks. These commands take the following form:

$ celery –A celery_runner <command>

The main tasks to view the status of your workers are as follows:

• status: This prints the running workers and if they are up
• result: When passed a task id, this shows the return value and final status of the task
• purge: Using this, all messages in the broker will be deleted
• inspect active: This lists all active tasks
• inspect scheduled: This lists all tasks that have been scheduled with the eta argument
• inspect registered ...
