> Add metrics to show actual cpu and memory utilization for each node and aggregated for the entire cluster. This is information is already passed from NM to RM in the node status update.
> We have been running with this internally for quite a while and found it useful to be able to quickly see the actual cpu/memory utilization on the node/cluster. It's especially useful if some form of overcommit is used.
