HDFS page in the Hadoop view

The HDFS page in the Hadoop view enables insights over current and forecasted utilization level for the HDFS service.

To access the page, in the TrueSight console navigation pane, click Capacity Views > Hadoop > Hadoop View, and in the vSphere Infrastructure page, click the HDFS tab.

The data in the page is categorized based on different subsystems and grouped under separate tabs. Click a tab to view the metrics for that subsystem:

SubsystemDescription
Summary
Displays a table with key performance indicators for HDFS
NodesDisplays a table with node level data about HDFS utilization
DetailDisplays HDFS 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:
