Aitozi commented on issue #8455: [FLINK-12284]Fix the incorrect inputBufferUsage metric in credit-based netowork mode URL: https://github.com/apache/flink/pull/8455#issuecomment-493109896 Thanks @zhijiangW for sharing your thoughts on this issue. Although the semantics of `inputBufferUsage` means the buffer occupied by `RemoteChannel` which may fill with data or not as you mentioned in credit-based mode in the moment, But I think this PR taking the exclusive buffer into account, which will make the semantics of this more close to the original intention. I'am also ok to stay the same until the time of introducing new network related metrics. I think we are short of more detail metric about credit-based network model too. Thanks for remind of the PR title format, I will pay more attention to this.:)
