Anubhav Dhoot commented on YARN-3467:
-------------------------------------
Attaching the ApplicationAttempt page. It does show the number of running
containers. But it does not show actual allocated resources overall for the
application attempt.
> Expose allocatedMB, allocatedVCores, and runningContainers metrics on running
> Applications in RM Web UI

> Key: YARN-3467
> URL: https://issues.apache.org/jira/browse/YARN-3467
> Project: Hadoop YARN
> Issue Type: New Feature
> Components: webapp, yarn
> Affects Versions: 2.5.0
> Reporter: Anthony Rojas
> Assignee: Anubhav Dhoot
> Priority: Minor
> Attachments: ApplicationAttemptPage.png

> The YARN REST API can report on the following properties:
> *allocatedMB*: The sum of memory in MB allocated to the application's running
> containers
> *allocatedVCores*: The sum of virtual cores allocated to the application's
> running containers
> *runningContainers*: The number of containers currently running for the
> application
> Currently, the RM Web UI does not report on these items (at least I couldn't
> find any entries within the Web UI).
> It would be useful for YARN Application and Resource troubleshooting to have
> these properties and their corresponding values exposed on the RM WebUI.
