Prabha Manepalli commented on YARN-3881: ---------------------------------------- [~BINGXUE QIU] If you are not currently working on this, Can I take this up now. Thanks. > Writing RM cluster-level metrics > -------------------------------- > > Key: YARN-3881 > URL: https://issues.apache.org/jira/browse/YARN-3881 > Project: Hadoop YARN > Issue Type: Sub-task > Components: timelineserver > Reporter: Zhijie Shen > Assignee: Zhijie Shen > Priority: Major > Labels: YARN-5355 > Attachments: metrics.json > > > RM has a bunch of metrics that we may want to write into the timeline backend > to. I attached the metrics.json that I've crawled via > {{http://localhost:8088/jmx?qry=Hadoop:*}}. IMHO, we need to pay attention to > three groups of metrics: > 1. QueueMetrics > 2. JvmMetrics > 3. ClusterMetrics > The problem is that unlike other metrics belongs to a single application, > these ones belongs to RM or cluster-wide. Therefore, current write path is > not going to work for these metrics because they don't have the associated > user/flow/app context info. We need to rethink of modeling cross-app metrics > and the api to handle them. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: yarn-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: yarn-issues-h...@hadoop.apache.org
