celery_queue_length is not getting values always zero

[ahelmy]

Thank you for this project. We are using it in our company, however this metric not working celery_queue_length always have zero. We are using redis.

@danihodovic your help please :)

Hi Ali. The queue length is working at my job. You will have to provide more information if we are going to debug this together.

[ahelmy]

I am using docker version 0.5.3. Do you think if used last version would matter?

[danihodovic]

The queue length only works for RabbitMQ. Are you using RabbitMQ?

[ahelmy]

No using redis. No way to make it work? Or a way to get the value

[ahelmy]

If no way please check this PR updating documentation https://github.com/danihodovic/celery-exporter/pull/191

What is meant in this ticket that it's not supported? Especially since the README has been updated to say that the celery_queue_length only works with RabbitMQ?

Our celery broker is redis and we can see some queue length data in our grafana dashboard,

...using this query,

[ahelmy]

Can you share celery configuration in python project, for example are you override default name of queue ?

[paxw-panevo]

We have different queues including the default queue called "default"

[ahelmy]

and is the default one showed in the queue_length metric ?

[paxw-panevo]

The default queue is showing the value of 0, true. But we were expecting that since we don't use that queue as much (if at all) and very likely the tasks are all consumed once celery queue length data is retrieved. At least that's what we think is going on based on what tasks we run and when.

I figured out the problem and created PR. Its about priority and queue names.
