------------------------------------

Hi [~akalashnikov]. For {{inputQueueLength}}, we considered the case of 
{{LocalInputChannel}} by obtaining the number of buffers in view. But for 
inputQueueSize, only the buffer in {{RemoteInputChannel}} is considered.  There 
seems to be some inconsistency here, do you have any thoughts on this?

> Add metric of the total real size of input/output buffers queue

> Right now we have the metric of the length of input/output buffers queue but 
> since buffer debloater has been introduced this metric is not always helpful 
> because the real size of each buffer can be different. So it is an idea to 
> add a new metric that shows the total size of buffers in the queue.
