---------------------------------
Summary: add more fine-grained metrics that measure write
performance
Key: YARN-3512
URL: https://issues.apache.org/jira/browse/YARN-3512
Project: Hadoop YARN
Issue Type: Sub-task
Components: timelineserver
Reporter: Sangjin Lee
Assignee: Sangjin Lee
We need more fine-grained metrics in the load testing tool that measure the
write performance of the timeline service. Currently it only captures the
number of writes and bytes per sec from the API point of view. But the actual
storage implementation may turn them into many more/fewer writes to the storage
itself. We need more fine-grained data about what's going on in terms of actual
writes to storage.
