HP XP Array Manager Software - Manual (Page 45)

Description Item
Select a monitoring term to narrow the range of statistics to display in the window.
Starting and ending times for collecting statistics are displayed on both sides of the slide
bar. Performance Monitor stores the monitoring data between these times, and you can
specify desired term within this range as the target of display in lists and graphs.
For example, to view statistics within the range of 10:30 July 1 2007 to 10:30 July 2
2007, set the From box to 2007/07/01 10:30, set the To box to 2007/07/02
10:30
, and then click Apply.
To set a date and time in the From and To boxes, do either of the following:
• Move the slider to the left or to the right.
• In the text box, select the number that you want to change. Next, click the upward
or downward arrow button.
When you specify dates and time in the From and To boxes, Performance Monitor
calculates the length (in minutes) of the specified period and displays the calculated
length. When calculating the length in minutes, Performance Monitor rounds up the
fraction.
The From and To boxes are unavailable if the monitoring data (that is, obtained statistics)
is not stored in the storage system.
The Real Time option is unavailable when the Physical tab is active.
Monitoring Term
Select this option to view statistics in real-time mode, where statistics are updated at a
gathering interval you specify between 1 and 15 minutes.
When you select the Real Time option, use the list to select the number, between 5 and
90, of recent collections of statistics to display in the graph. This setting determines the
range of recent statistics to be displayed in the graph. For example, if the gathering
interval is 1 minute and you select 90 from the list, the graph displays statistics obtained
in the last 90 minutes (multiplying 1 minute by 90 times).
