django-huey-monitor

Django based tool for monitoring huey task queue

Current implementation will just store all Huey task signals into the database and display them in the Django admin.

Quickstart

pip install django-huey-monitor

INSTALLED_APPS = [
    #...
    'bx_django_utils', # https://github.com/boxine/bx_django_utils
    'huey_monitor',
    #...
]

Note: You must normally not change your Huey tasks.

Collect main-/sub-tasks

Huey monitor model can store information about task hierarchy. But this information can't be collected automatically. You have to store these information in your Task code.

e.g.:

@task(context=True)
def sub_task(task, parent_task_id, chunk_data):
    # Save the task hierarchy by:
    TaskModel.objects.set_parent_task(
        main_task_id=parent_task_id,
        sub_task_id=task.id,
    )
    # ... do something with e.g.: chunk_data ...


@task(context=True)
def main_task(task):
    for chunk_data in something:
        sub_task(parent_task_id=task.id, chunk_data=chunk_data)

Working example can be found in the test app here: huey_monitor_tests/test_app/tasks.py

Collect progress information

Running task can store progress information in a similar way as tqdm. So it's possible to see the progress in admin.

Minimal example:

@task(context=True)
def foobar_task(task, list_to_process):
    process_info = ProcessInfo(
        task,
        desc='A description of this Job',
        total=len(list_to_process)
    )

    for item in list_to_process:
        # ...to something with the {item}...
        process_info.update(n=1) # add the information that one item was processed

It is also possible to divide the work to several tasks and collect information about the processing of main-/sub-tasks.

Working example can be found in the test app here: huey_monitor_tests/test_app/tasks.py

run test project

Note: You can quickly test Huey Monitor with the test project, e.g:

~/django-huey-monitor$ ./manage.sh run_testserver

or in an isolated Docker container:

~/django-huey-monitor$ make up

~/django-huey-monitor$ make install-poetry
~/django-huey-monitor$ make install
~/django-huey-monitor$ make up

It's also possible to run the test setup with SQLite and Huey immediate setup without docker:

~$ git clone https://github.com/boxine/django-huey-monitor.git
~$ cd django-huey-monitor
~/django-huey-monitor$ ./manage.sh run_testserver
