      Description

      Now, the 'inPoolUsage' and 'inputExclusiveBuffersUsage' describe the overall situation of a task's network usage. Sometimes, when the back pressure was present, I found the value of 'inPoolUsage' or 'inputExclusiveBuffersUsage' were very low, beacuse they were averaged by the input channel whose buffer usage is low. I propose to add a new metric for each task to record the maximum buffer usage of all input channels belonged to this task.
