View the Monitoring Results
To view the results of monitoring, use the Auto LUN window of Performance Monitor. When you select
the Auto LUN tab, the Auto LUN window is displayed. In that window, select a desired tab in the tree
left side in the window and the icons which information you can view are displayed in the tree. Select
the icon with information you want to view and the statistics obtained in the storage system are
displayed in the list on the right side of the tree.
Figure 19 Auto LUN Window
.
The information you can view by selecting each tab for the tree is explained below.
• Physical tab: View usage statistics about resources in the storage system.
• LDEV tab: View statistics about workload on disks.
• Port-LUN tab: View statistics about traffic at ports and LU paths in the storage system.
• WWN tab: View statistics about traffic at path between host bus adapters (HBAs) and ports.
Two sliders are displayed on the upper right of the Auto LUN window. To the left and right of the two
sliders, dates and times are displayed. The term between these dates and times is the period in which
statistics are stored. If the date and time on the left is 2007/03/27 16:00 and the date and time
on the right is 2007/03/28 16:00, you can view usage statistics for the period of 2007/03/27
16:00
to 2007/03/28 16:00.
If you change the dates and times in the From and To boxes, you can specify the range of statistics
that should be displayed in the window. For example, if the window displays statistics for the last one
month, you can change the values in the From and To boxes to display the statistics for the last week
only or to display the statistics for the last three days only.
When monitoring ports, LU paths or host bus adapters in the Port-LUN tab or the WWN tab, you can
view the monitoring results in near-real time. To view the monitoring results in real time, select the
Real Time option which is included in the Monitoring Term area of the Auto LUN window. The
information in the window will be updated at the specified gathering interval (every 1 to 15 minutes).
