Erik Krogen created HDFS-10873: ---------------------------------- Summary: Add histograms for FSNamesystemLock Metrics Key: HDFS-10873 URL: https://issues.apache.org/jira/browse/HDFS-10873 Project: Hadoop HDFS Issue Type: Sub-task Components: namenode Reporter: Erik Krogen Assignee: Erik Krogen
It could be useful to have full histograms for how long operations are holding the namesystem lock in addition to just rate information. This will, however, be a large number of emitted metrics and likely require more coordination, so it may be best to have this be separately configurable from more simple namesystem lock metrics. -- This message was sent by Atlassian JIRA (v6.3.4#6332) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
