Viewing Usage Statistics on Channel Processors
Performance Monitor monitors channel processors in each channel adapter and
lets you view the average and the maximum usage rate in a specified period.
Performance Monitor also displays a graph illustrating changes in channel
processor usage within that period.
To view usage statistics about channel processors:
1. Ensure that the Performance Management 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.
When you view usage statistics about channel processors, the items
displayed in the list by selecting longrange and shortrange are the same.
4. In the tree, do one of the following:
– If you want to view usage statistics about all the channel processors in
your storage system, select the Client-Host Interface Processor
(CHIP) folder.
– If you want to view usage statistics about channel processors in a
channel adapter, double-click the Client-Host Interface Processor
(CHIP) folder and then select the desired channel adapter.
The list on the right displays usage statistics about the channel 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 Performance
Management Window, Physical Tab).
5. To display a graph illustrating changes in usage rate for channel
processors, select the desired channel 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.
