Varun Saxena commented on YARN-5553:
------------------------------------

Also can you attach complete REST output (specifiy fields=ALL) so that we can check when CONTAINER_CREATED and CONTAINER_FINISHED events were published and other info.

> 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.
