Sangjin Lee commented on YARN-4821:
-----------------------------------
I don't think it needs to be that sophisticated. It can be as simple as looking
at the last publishing time, and decide whether to emit the value at hand.
There may well be more interesting details to this, but let's figure it out
here.
> have a separate NM timeline publishing interval

> Key: YARN-4821
> URL: https://issues.apache.org/jira/browse/YARN-4821
> Project: Hadoop YARN
> Issue Type: Sub-task
> Components: timelineserver
> Affects Versions: YARN-2928
> Reporter: Sangjin Lee
> Labels: yarn-2928-1st-milestone
>
> Currently the interval with which NM publishes container CPU and memory
> metrics is tied to {{yarn.nodemanager.resource-monitor.interval-ms}} whose
> default is 3 seconds. This is too aggressive.
> There should be a separate configuration that controls how often
> {{NMTimelinePublisher}} publishes container metrics.
