lining updated FLINK-14815:
---------------------------
Description:
* SubTask
** pool usage: outPoolUsage, inputExclusiveBuffersUsage,
inputFloatingBuffersUsage.
*** If the subtask is not back pressured, but it is causing backpressure (full
input, empty output)
*** By comparing exclusive/floating buffers usage, whether all channels are
back-pressure or only some of them
** back-pressured for show whether it is back pressured.
* Vertex
** pool usage: outPoolUsageAvg, inputExclusiveBuffersUsageAvg,
inputFloatingBuffersUsageAvg
** back-pressured for show whether it is back pressured(merge all iths
subtasks)

{code:java}
public final class IOMetricsInfo {
private final float outPoolUsage;
private final float inputExclusiveBuffersUsage;
private final float inputFloatingBuffersUsage;
}
{code}
JobDetailsInfo.JobVertexDetailsInfo merge use Math.max.(ps: outPoolUsage is
from upstream)
> Expose network metric in IOMetricsInfo
