[jira] [Commented] (FLINK-24657) Add metric of the total real size of input/output buffers queue

["Piotr Nowojski (Jira)" <ji...@apache.org>]

Piotr Nowojski commented on FLINK-24657:
----------------------------------------

We had some discussion around that in the PR [~Weijie Guo], please take a look there, especially https://github.com/apache/flink/pull/17660#discussion_r754096460

In short, maybe we should converge input metrics to ignore local channels everywhere? :thinking:

> Right now we have the metric of the length of input/output buffers queue but since buffer debloater has been introduced this metric is not always helpful because the real size of each buffer can be different. So it is an idea to add a new metric that shows the total size of buffers in the queue.
