Enabling performance thresholds Performance thresholds Disabling performance thresholds

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

Context

You can enable 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.
Disk Utilization
Percent of time busy
Percent of sequential I/Os
Percent of sequential I/Os
Nonvolatile Storage
Percent of time full
Average cache holding time ESS Measured in seconds Status: Enabled
Measured in seconds
I/O rate
Total number of I/O requests
VDisk I/O rate
Total number of virtual disk I/Os for each I/O group
VDisk bytes/second
Virtual disk bytes per second for each I/O group
MDisk I/O rate
Total number of managed disk I/O for each managed disk group
MDisk bytes per second
For each managed disk group
Data transaction (count per second)
Total server-level data transaction rate
Data transaction for updates (count per second)
Total server-level data transaction rate for updates to system objects
Steps

Perform the following steps to enable thresholds that have been disabled (the default is enable):

  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. 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. From the Thresholds table, select the disabled threshold that you want to enable.
  6. Click Enable.
    Note:Note: For some devices, a filter is associated with a threshold. In these cases, you receive a message, such as: This threshold is associated with a filter. Do you want to enable the filter? Click Enable filter or click Do not enable filter. If you select Enable filter, the filter is enabled along with the threshold.
  7. Repeat this procedure for each threshold that you want to enable.
Result

The selected thresholds are now enabled.
