>
> 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.
