[~rohithsharma], should we close this as "Not A Problem", if you are fine with 

> [ATSv2] "metrics" for YARN_CONTAINERS are displayed as empty.

> metrics for YARN_CONTAINER entity types are displayed as empty. For master 
> containers some values are displayed but for other containers randomly it 
> displays metric values.
> I think the behavior is due to publishing of container metric in monitor 
> thread from NodeManager. There are 2 issues I observe is 
> # Some containers has metric values CPU-Memory, some are empty. 
> # The CPU-Memory values taken are from current usage which monitor thread 
> reports. But issue with it is *aggregationOp* is SUM. So Each time monitor 
> thread reported values is being added and give some bigger values. But 
> ideally it is not actual usage. 
> I think CPU-MEMORY metric values for yarn-containers entities should be 
> allocated values.
