Modifying performance thresholds Performance thresholds Filtering performance thresholds

Perform this task to modify performance threshold properties for a storage device.

Context

The user can modify the following thresholds on the Performance Threshold summary panel for a selected device.

Note:Note: Not all of the listed thresholds are displayed for a selected device. The thresholds are device dependent.

Steps

Perform the following steps to modify thresholds for selected devices.

  1. On the IBM Director Tasks pane, click Multiple Device Manager. The Multiple Device Manager (MDM) tasks are displayed.
    Note:Note: You can also view the Performance Threshold summary panel by accessing the IBM Director Scheduler, or by selecting the performance data collection task in the IBM Director Task pane.
  2. Click Manage performance. MDM Performance Manager 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. From the Thresholds table, select a single threshold for a single device.
  6. Click Properties. The properties for the selected device are displayed.
  7. Modify one or more of the following properties:
    • Warning level
    • Error level
    • Alert level
  8. Click OK to commits the changes.
  9. Repeat this procedure for each threshold that you want to modify.
Result

The selected thresholds are now modified.
