How to get queue size?

Community Support

Hi everyone,

I would like to know if there is a way to obtain the size of the Temporal queue and assess the overall queue state (I’m aware of the talk here [1]).

I came across some metrics that seem related to the queue, such as “taskqueue_processed,” “taskqueue_deleted,” “taskqueue_outstanding,” and “loaded_task_queue_count.” However, I couldn’t find any documentation explaining how these metrics relate to the actual queue.

Any insights would be appreciated!

Best regards,
Sanel

Enhanced task queue info was added since the thread you linked to:

Thank you for your fast reply @tihomir :slight_smile: Can I monitor these metrics then [1] or I’ll have to use SDK or RPC? I can’t find them in my Temporal prometheus scrape link, I assume they were added after 1.23? My version is 0.12.0 (server 1.23.0) (ui 2.26.2)

Quick update: after updating Temporal server to 1.25.2, I see approximate_* metrics on the scrape endpoint. Thank you @tihomir!
