Displaying the Usage Monitor Graph
When usage monitoring is running, the Usage Monitor window can display user-selected remote copy
I/O statistics in real time.
The usage monitor graph plots the 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 the data being displayed. A value on the y-axis varies according
to the maximum value of the statistical data that is displaying. If the value on the y-axis exceeds
10,000,000, the value is displayed in exponential notation (e.g., 1E7 = 1×10 7 = 10,000,000; 2E8
= 2×10 8 = 200,000,000).
To display the usage monitor graph:
1. Make sure that usage monitoring is running (Monitoring Switch = Enable). The usage monitor
graph can only be displayed when monitoring is on.
2. Right-click the graph area of the Usage Monitor window, and select Display Item to open the
Display Item window (see Figure 72 on page 173).
