Aitozi commented on issue #8455: [FLINK-12284][Network,Metrics]Fix the incorrect inputBufferUsage metric in credit-based network mode URL: https://github.com/apache/flink/pull/8455#issuecomment-496077999 Hi, @zhijiangW thanks for your detail explanation, I make a conclusion below Non-credit-based mode: - InPoolUsage Credit-based mode: - exclusiveInPoolUsage exclusiveBufferUsed/exclusiveBufferTotal(all initial credit) - floatingInPoolUsage floatingBufferUsed/floatingBufferTotal - InPoolUsage combine with exclusiveInPoolUsage and floatingInPoolUsage I think this looks better to distinguish the buffer usage between floating and exclusive in credit-based mode and also give a view of the overall perspective with inPoolUsage metric.
