--------------------------------------
Summary: Create isCausingBackPressureRatio and
isCausingBackPressure metrics
Key: FLINK-20718
URL: https://issues.apache.org/jira/browse/FLINK-20718
Project: Flink
Issue Type: Sub-task
Components: Runtime / Metrics
Reporter: Piotr Nowojski
Fix For: 1.13.0
create {{isCausingBackPressureRatio}} and {{isCausingBackPressure}} metrics.
Based on either {{!isBackPressured && inPoolUsage > 0.5}} or {{!isBackPressured
&& idleTimeMsPerSecond < 1ms}} . Probably the latter version is better, as it
would neatly ignore the problem that {{inPoolUsage}} metric doesn't work with
{{LocalInputChannel}}
