YARN Dashboard
The YARN Dashboard provides key information for queue, application, container, and NodeManager host metrics.
This dashboard includes the following paragraphs:
• Application Runtime Duration by Queue
• Top N Applications by Number of Containers Requested
• Top N Applications by Number of Containers Failed
• Top N Hosts by Number of Containers Executed
• Top N Hosts by Number of Application Failures
• Top N Hosts by Localization Time
• Top N Hosts by Container Launch Delay
Most of these paragraphs have titles that are self-explanatory. One of them is described below to provide more context:
| Paragraph | Description |
|---|---|
| Top N Applications by Number of Containers Failed |
This paragraph shows the top jobs with the highest number of failed containers and the reason for each failure, so that you can quickly identify which containers failed and why. |
