Use the Performance Monitor option to select logical drives and controllers to monitor or to change the polling interval.
Important: Chosen settings apply to this monitoring session only (that is, the settings will revert back to the default settings if you exit and re-open the Performance Monitor).
To select logical drives and controllers to monitor, press the Shift + click or Ctrl + click to select multiple contiguous or non-contiguous devices in the list, respectively. To select every device, select Select All.
Note: The Storage Subsystem Totals row can be selected or unselected for display on the Settings dialog.
To change the polling interval, choose a number of seconds in the spin box. Each time the polling interval elapses, the Performance Monitor re-queries the Storage Subsystem and updates the statistics in the table.
If you are monitoring the Storage Subsystem in real time, update the statistics frequently by selecting a short polling interval, for example, 5 seconds.
If you are saving results to a file to look at later, choose a slightly longer interval, for example, 30 to 60 seconds, to decrease the system overhead and the performance impact.
To apply the new settings, select OK.
