Viewing Usage Statistics about Disk Processors (DKPs)
Performance Monitor monitors disk processors (DKPs) and displays statistics about the average and
the maximum usage rate in a specified period. Performance Monitor also displays a graph that
illustrates changes in disk processor usage within that period.
To view usage statistics about disk processors:
1. Ensure that the Auto LUN window is displayed.
2. In the tree, click the Physical tab.
3. In the list above the tree, select the storing period of statistics from longrange and shortrange for
display.
For details on the types of storing period of statistics, see “
Understanding Statistical Storage
Ranges ” on page 16.
When you view usage statistics about disk processors, the items displayed in the list by selecting
longrange and shortrange are the same.
4. In the tree, double-click the DKA folder.
5. Click DKP from below the DKA folder.
The list on the right displays usage statistics about disk processors. The displayed statistics are
the average and the maximum usage rates for the period specified in the From and To boxes.
NOTE:
If you change the date and time in the From and To boxes and then click Apply, Performance
Monitor recalculates usage rates and updates information in the list. To change the date and
time in From and To boxes, use the arrow buttons and the sliders (for details, see “
Auto LUN
Window, Physical Tab ” on page 31).
6. To display a graph that illustrates changes in usage rate for disk processors, select the desired
disk processors in the list and then click Draw.
NOTE:
The range of monitoring and the gathering interval affects the time period represented by a
graduation on the horizontal axis.
