----------------------------------
Summary: Add cpu and memory utilization per node and cluster-wide
metrics
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
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.
