HP XP Array Manager Software - Manual (Page 49)

Enables you to view statistics about traffic at path between host bus adapters (HBAs) and ports
(see “ Traffic between HBAs and Storage System Ports ” on page).
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). Note that you
cannot view the monitoring results displayed in the Physical tab and the LDEV tab in real time.
