Hosts Disks Overview

How to view the status of all disks in a cluster.

In the left menu, click Hosts > Disks Overview to display an overview of the status of all disks in the deployment. The statistics exposed match or build on those in iostat, and are shown in a series of histograms that by default cover every physical disk in the system.

Adjust the endpoints of the time line to see the statistics for different time periods. Specify a filter in the box to limit the displayed data. For example, to see the disks for a single rack rack1, set the filter to: logicalPartition = false and rackId = "rack1" and click Filter. Click a histogram to drill down and identify outliers. Mouse over the graph and click to display additional information about the chart.
