@shrekris-anyscale is this needed in addition to #37939 ? |
|
Yes, that PR is tackling a different problem: the queue metric is not getting set when there's no traffic. This change is fixing the issue where queued requests that get disconnected aren't counted properly. As a sanity check, the unit test in this PR fails locally with just the changes in #37939. |
|
actually, i don't think my pr will fix the issue. we decrease the metrics and set it whenever the request is finished. We can proceed to checkin this pr, and close mine. |

would be an issue if different exceptions happens?

Yes, it would. I changed the code to a try-finally block, so the metric is decremented no matter what exception is raised.

add try here, so that we don't need to have incremented_queue_metric.

Good idea, that makes the code simpler. I made the change.

…isconnects (ray-project#37965) The `ray_serve_deployment_queued_queries` metric tracks the number of queries that have yet to be assigned a replica. If a client disconnects before its query has been assigned a replica– but after the metric has counted their query– the query terminates, but the metric doesn't decrease. This change decrements `ray_serve_deployment_queued_queries` when a queued request is disconnected. Signed-off-by: Edward Oakes <ed.nmi.oakes@gmail.com>
