> Currently app level aggregation is done every 15 seconds.
> And we consider last reported metric value for each entity belonging to an app for aggregation.
> We however merely update the corresponding metric values for the entity on put. We never
remove the entries.
> But it is possible that multiple entities finish during lifetime of an application. We
however continue to consider them till the end.
> We should however not consider metric values of entities unless reported within the 15
second period.
> Consider containers. For a long running app, several containers would start and end at
various times during the lifetime of an app.
> To consider metrics for all the containers throughout the lifetime of app, hence wont
be correct.
