Naganarasimha G R commented on YARN-3513:
-----------------------------------------

Thanks for reviewing [~gtCarrera9]
bq. If so does it harm to only update those four variables on debug only
+1 will do these modifications which will remove unwanted computations when debug is not enabled

bq.  I think we're changing the meaning of vmemStillInUsage and pmemStillInUsage. Would you
please elaborate a little bit more the current way makes more sense than the previous way?

Well the names may be debatable, but my intention was to actually capture the total usage
when the monitors ran, so that it includes the usage of containers which are about to be killled
as part of monitor's run. Well can keep it as earlier but felt this will be more useful to
get the actual usage... thoughts ?
