Perform this task to view performance threshold properties for a storage device. Performance Manager lists performance properties and statistics in the Performance Threshold summary table.

Steps

Perform the following steps to view performance threshold properties for a storage device:

  1. From the IBM Director Task pane, click Multiple Device Manager.
  2. Click Manage performance. The performance management tasks are displayed.
  3. Drag the Thresholds icon from the Task pane to the Group Contents pane of the IBM Director.
  4. Drop the icon on a storage device in the Group Contents pane. The Thresholds panel opens.

    The Threshold summary panel lists the thresholds, threshold status, threshold values, alert, and filter information available for selected storage devices. Each device has multiple line items, one for each threshold.

  5. Select a single threshold for a single device from the Thresholds table to view its properties.
  6. Click Properties to view or change threshold properties. The properties for the selected device are displayed.
