Celery Prometheus Exporter

Celery Exporter is a Prometheus metrics exporter for Celery 4, written in Clojure.

Here the list of exposed metrics:

• celery_tasks_total exposes the number of tasks currently known to the queue labeled by instance, name, queue and state.
• celery_tasks_runtime_millis tracks the number of milliseconds tasks take until completed as histogram labeled by name, queue and instance.
• celery_time_spent_in_queue_millis exposes a histogram of task latency, i.e. the time until tasks are picked up by a worker from when they are published to the queue.
