Hua Liu reopened HDFS-9882: --------------------------- > Add heartbeatsTotal in Datanode metrics > --------------------------------------- > > Key: HDFS-9882 > URL: https://issues.apache.org/jira/browse/HDFS-9882 > Project: Hadoop HDFS > Issue Type: New Feature > Components: datanode > Affects Versions: 2.7.2 > Reporter: Hua Liu > Assignee: Hua Liu > Priority: Minor > Attachments: 0001-Add-heartbeatsTotal-metric.patch > > > Heartbeat latency only reflects the time spent on generating reports and > sending reports to NN. When heartbeats are delayed due to processing > commands, this latency does not help investigation. I would like to propose > to add another metric counter to show the total time. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
