Displaying the Usage Monitor Graph
When usage monitoring is running, the Usage M onitor 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 (for example, 1E7 = 1×10
7
= 10,000,000 ; 2E8 = 2×10
8
= 200,000,000). The Update field d isplays the most recent data sample time for the data on the graph.
To display the usage m onitor graph:
1. Make sure that usage monitoring is running (M o nitoring Switch = Enable). The usage monitor
graph ca n only be displayed when monitoring is on.
2. Right-click the graph area of the Usage Monitor window, and click Display Item to open the
Display Item dialog box (see Figure 36 on page 91).
3. To display I/O statistics for a ll LDEVs to be monitored in the storage system, click All Volumes.
To display I/O statistics for a specificvolume, click Volume, and then enter the desired volume
by selecting the port and entering the GID (00-FE) and LUN (000-7FF).
Note: If you specify a n
unmounted volume, the graph is not displayed.
Note: The LDKC number:CU number:LDEV number is displayed on the top of the g raph. If #
is added to the end of an LDEV number (for example, 00: 00:3C#) , the LDEV is an external
volume. For details on external volumes, see the HP StorageWorks XP24000 External Storage
Software User’s Guide.
To display I/O statistics for the sidefile data, click CLPR, and then select the desired CLPR from
the
drop-down list.
4. In the Monitor Data box, select the I/O statistics data that you want to display on the g raph. You
must click at least one box. Table 20 on page 91 describes the I/O statistics data.
Note: To display the Average Transfer Rate, Pair Synchronized, or SideFile, you cannot select
any other statistics at the same time. The graph can only display one type of d ata at a time:
I/O
count, rate, or percent.
5. Click Set to close the Display Item dialog b ox. The Usage Monitor window now displays a graph
showing the selected I/O statistics data for the selected LU(s).
To enlarge the displayed graph, right-click the graph, and click the Large Size command. To
return the graph to normal size , right-click the graph, and click the Normal Size command.
Note: The host group name will b e indicated in up to 8 characters at the top of the graph if the Normal
