Selecting data to be graphed
The usage monitor graph plots the I/O data that you specify. On the graph:
•
The x-axis indicates time.
•
The y-axis indicates the number of I/Os during the sampling period.
•
The legend on the right side shows the data being displayed.
The value on the y-axis varies according to the maximum value of the statistical data appearing
in the graph. If the y-axis value exceeds 10,000,000, the value is shown in exponential notation
(for example, 1E7 = 1 x 10
7
= 10,000,000; 2E8 = 2 x 10
8
= 200,000,000).
Procedure 16 To specify I/O data to be graphed
1. Make sure that usage monitoring is running (Monitoring Switch = Enable). The usage monitor
graph can be viewed only when monitoring is on.
To enable usage monitor, see the HP XP P9000 Performance for Open and Mainframe Systems
User Guide.
