[jira] [Reopened] (YARN-10353) Log vcores used and cumulative cpu
in containers monitor
[ https://issues.apache.org/jira/browse/YARN-10353?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Eric Payne reopened YARN-10353:
-------------------------------

> We currently log the percentage/cpu and percentage/cpus-used-by-yarn in the Containers Monitor log. It would be useful to also log vcores used vs vcores assigned, and total accumulated CPU time.
> For example, currently we have an audit log that looks like this:
