> Key: YARN-10450
> URL: https://issues.apache.org/jira/browse/YARN-10450
> Project: Hadoop YARN
> Issue Type: Improvement
> Components: yarn
> Affects Versions: 3.3.1
> Reporter: Jim Brennan
> Assignee: Jim Brennan
> Priority: Minor
> Attachments: NodesPage.png, YARN-10450.001.patch, YARN-10450.002.patch

> 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.
