Eric Badger commented on YARN-10450: ------------------------------------ The patch itself looks good to me. However, I'm wondering if "Mem Utilization" is the correct phrase to convey what we mean. To me this means "Mem Used" / "Mem Avail". But in this case it's the actual utilization of the node. And "Mem Used" isn't really the actual memory that's being used. It's the memory that is allocated to that node via YARN. [~Jim_Brennan], [~epayne] do you have any thoughts on making this terminology a little more clear on the UI? > 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 > 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.

It's especially useful if some form of overcommit is used. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
