Graph Line button
The example in this figure shows that the dialog was used to set the display of multiple LUNs in the same graph window. In this example, the <Graph Line> button is placed at the upper right so that the names of multiple graph lines can be seen. Clicking this button displays a window that explains the graph line names.
Set Vertical Axis button
Clicking the <V-Axis> button at the upper right of the screen displays the dialog shown below. In this dialog, the maximum value of the vertical axis of a graph can be specified.
The value can be entered directly. However, clicking the <Adjust to Maximum Value> button automatically calculates and displays the maximum value for a graph. Clicking the <Reset to Default> button sets the maximum value of the standard vertical axis of performance management.
Latest Information button
Clicking the <Latest Graph> button in the lower part of the screen displays a graph for the latest date and time.
Previous One Week, Previous Day, Previous One Hour, Next One Week, Next Day, and Next One Hour buttons
Clicking the <Previous Week>, <Previous Day>, <Previous Hour>, <Next Week>, <Next Day>, or <Next Hour> buttons in the lower part of the screen reads and displays performance information from stored performance data.
Date Specification button
The following dialog is displayed when the <Date Specification> button on the part of the lower right of the screen and an arbitrary date can be specified. The graph is displayed centering on a specified date. You can specify a period of up to 7 days. The range which can be input is different according to the type of the time axis.
Peak button
When one week or one day is indicated in a displayed graph, the <Peak> button in the upper part of the screen can be used to add or delete graph lines in the graph. These graph lines are plotted with only the maximum vertical axis data values of the graph in the respective unit of time. The <Peak> button is displayed in the graph if an item other than R/W, R/W/P, and total had been selected in the "Performance Graph" dialog. The <Peak> button is not displayed in the performance graph for RAIDGroup and number of active disks.
Changing the time axis in a graph window
Right-clicking in the Performance Graph window as shown below displays a popup menu. From this menu, menu items can be selected to display a window with a different time axis. In the menu, one menu item for displaying a graph with a shorter time axis is adjusted according to the mouse position. For example, right clicking at around 22:00 in the graph displays a pop-up menu for displaying a one-hour graph at 22:00 as shown in the figure below.
Clicking in the one-hour graph in the Performance Graph window as shown below displays a pop-up menu. From this menu, the following menu items can be selected: item for redisplaying of the window with a different center for the time axis and item for increased magnification of the window display. The center of the time axis is the time adjacent to the mouse position. For example, click at around 14:10 in the graph as shown in the figure below. 14:10 then comes to the center of the graph, and a pop-up menu for displaying a one-hour graph from 13:40 to 14:40 and a pop-up menu for displaying a 20-minute graph from 14:00 to 14:20 are displayed.
Year-month-day-time is displayed in the graph window to indicate the beginning time of the displayed graph.
