The usage monitor graph plots user-selected I/O statistics (up to 65 data points) on an x-y graph.

The x-axis displays time. The y-axis displays the number of I/Os during the last sampling period.

The legend (right side of the graph) indicates data being displayed. A value on the y-axis varies

according to the maximum value of the statistical data displayed. If the value on the y-axis exceeds

10,000,000, the value is displayed in exponential notation (for example,

1E7 = 1x10

= 10,000,000; 2E8 = 2x10

= 200,000,000).

1. Ensure that usage monitoring is running. The usage monitor graph is only displayed when

monitoring is on.

2. Right-click the graph area on the Usage Operations pane, and click Display Item. The Display

Item pane (Figure 67 (page 153)) appears.

3. In Select LU, do one of the following:

• To display I/O statistics for all LDEVs in the array, select Subsystem.

• To display I/O statistics for a specific journal group, select JNL Group, and enter a journal

group number (00-FF).

NOTE: If you specify an unused journal group, the graph is not displayed.

• To display I/O statistics for a specific LU, select Device, select a port (CL1-A to CLG-R),

and enter the G-ID (00-FE) and LUN (00-3FF).

NOTE: If you specify the unmounted LU, the graph is not displayed.

NOTE: When a graph displays, the CU and LDEV numbers appear above the graph.

If the logical volume is an external LU, # appears after the LDEV number. For more

information about external LUs, see the HP StorageWorks External Storage XP user guide.

4. In the Monitor Data box, select the I/O statistics data you want to display on the graph. You

must select at least one box. Table 30 (page 154) describes I/O statistics data.
