[~curino] - the two sub-tasks capture memory and CPU in NM metrics. Did you 
have anything else in mind to be done here? Otherwise, we could mark this as 

> [Umbrella] Capture container and node resource consumption
> ----------------------------------------------------------
>                 Key: YARN-2141
>                 URL: https://issues.apache.org/jira/browse/YARN-2141
>             Project: Hadoop YARN
>          Issue Type: Improvement
>          Components: nodemanager
>            Reporter: Carlo Curino
>            Priority: Minor
> Collecting per-container and per-node resource consumption statistics in a 
> fairly granular manner, and making them available to both infrastructure code 
> (e.g., schedulers) and users (e.g., AMs or directly users via webapps), can 
> facilitate several performance work.
