Piotr Nowojski created FLINK-12576: -------------------------------------- Summary: inputQueueLength metric does not work for LocalInputChannels Key: FLINK-12576 URL: https://issues.apache.org/jira/browse/FLINK-12576 Project: Flink Issue Type: Bug Components: Runtime / Metrics Affects Versions: 1.8.0, 1.7.2, 1.6.4 Reporter: Piotr Nowojski
Currently {{inputQueueLength}} ignores LocalInputChannels ({{SingleInputGate#getNumberOfQueuedBuffers}}). This can can cause mistakes when looking for causes of back pressure (If task is back pressuring whole Flink job, but there is a data skew and only local input channels are being used). -- This message was sent by Atlassian JIRA (v7.6.3#76005)
