Usage Monitor Graph

Select 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
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.
2. Right-click the graph and select Display Item from the menu that appears. The Display Item
dialog box displays.
3. In the Select Volume box, select one of the following:
ALL Volumes, to view I/O statistics for all LDEVs in the system. When selected, the LDKC
number, CU number, and LDEV number appear above the graph.
- A device ID ending in # (e.g., 00:00:3C #) indicates the LDEV is an external volume
(see HP StorageWorks P9000 External Storage for Open and Mainframe Systems User
Guide for more information about external drives).
- A device ID ending in X (e.g., 00:00:3C X) indicates the LDEV is a Thin Provisioning
virtual volume (see HP StorageWorks P9000 Provisioning for Open Systems User Guide
for more information on a virtual volumes).
Journal, to view I/O statistics for a specific journal. Enter a journal number (000-0FF) in
the Journal box.
Volume, to view I/O statistics for a specific LU. Select the LU Port (CL1-A to CLG-R) and
enter the GID (00-FE) and LUN (000-7FF).
4. In the Monitor Data boxes, select the I/O statistics data that you want to appear on the graph.
You must select at least one box.
