Hua Liu updated HDFS-9882: -------------------------- Status: Patch Available (was: In Progress) > Add heartbeatsTotal in Datanode metrics > --------------------------------------- > > Key: HDFS-9882 > URL: https://issues.apache.org/jira/browse/HDFS-9882 > Project: Hadoop HDFS > Issue Type: Task > Components: datanode > Reporter: Hua Liu > Assignee: Hua Liu > Priority: Minor > > 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 > either (1) changing the heartbeat latency to reflect the total time spent on > sending reports and processing commands or (2) adding another metric counter > to show the total time. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
