Configure the Disk Performance report

You can view disk activity, disk throughput, and disk operations within the Disk Performance report.

1. Click the Performance Reporting tab.
2. On the Live Performance Reporting page, click the Cluster drop down and select the cluster that you want to monitor.
3. Click the Report Type drop down and select Disk Performance.
4. In the Date Range fields, select a range to display, then click View Report.
   The date range should include the entire period of time when the cluster was behaving unexpectedly. The default setting is to view the last hour of data.
   The modules in the report are now populated with data for the cluster and date range you selected.
5. In the Disk Activity module, click the Disk breakout.
   To learn more about breakouts, refer to the Breakouts topic.
   To remove focus on a breakout, click the None breakout.
   NOTE High activity on a single disk or a few disks and low activity on the remaining disks might indicate performance issues on the OneFS cluster.
   On the left side of the module, you can now see a list of all disks that were not idle during the date range you specified. The disk at the top of the list had the most activity during the date range you selected.
6. In the Disk Throughput Rate module, click the Disk breakout.
   On the left side of the module, you can now see a list of all disks that were being written to or read from during the date range. The disk at the top of the list had the highest percentage throughput.
