Displays a table with key performance indicators for YARN
DetailDisplays YARN charts over time

Metrics per cluster are displayed in a tabular format.

By default, some columns are hidden. You can show or hide columns using the action menuthat is located next to the table title.

This topic contains the following sections:

Summary

Resource utilization and tasks statistics are displayed for each cluster.

Each row in the table represents a Hadoop cluster and displays the following metrics:
