Figure 13 Chart Y Axis Rate Drop-Down List, Detail Check Box, and the Drop-Down

List to Select the Item to be Displayed (Port-LUN Tab)

The Chart Y Axis Rate drop-down list lets you select the highest value of the Y-axis (the vertical

axis) of the graph.

If you select the Detail check box after drawing a graph by selecting the Draw button, the graph

displays detailed statistics as explained. The detailed statistics can be displayed only:

•When you select the Subsystem folder (

) in the tree and select a port in the list.

The graph displays detailed statistics about workloads on the port selected in the list. For

details on the graph, see Detail Statistics about Workload on a Port below.

•When you select LUN (

) in the tree and select a LUN (an address of a volume) in the list.

The graph displays detailed statistics about workloads on the LU path selected in the list. The

informationinthe graphdepends on theitemselectedin the drop-down listonthe rightof

the Detail check box. For details on the graph see Detail Statistics about Workload on an

LU Path below.

Viewing Port Workload Statistics

Figure 14 on page 42 shows an example of a graph displaying about workload of a port. In this

example,

the user selected the port CL1-A in the list and then select Draw. Note that, in this example, 1

minute is speciﬁed as the gathering interval. The graph contents changes depending on the selection of

the Detail check box as explained in Figure 14 on page 42. The ﬁgure shows the following:

• The workload on the port CL1-A is 200 IO/s at 8:00, and 300 IO/s at 10:00 (see the graph

on the left).

• For the

period of 7:59 to 8:00, the maximum workload on CL1-A is 300 IO/s. The average

worklo

ad on CL1-A is 200 IO/s. The minimum workload on CL1-A is 100 IO/s (see the graph on

the right).

• For the period of 9:59 to 10:00, the maximum workload on CL1-A is 400 IO/s. The average

workload on CL1-A is 300 IO/s. The minimum workload on CL1-A is 200 IO/s (see the graph

on the

right).

• When Detail is deselected, only one line appears in the graph. This line is equivalent to the line

Ave. (1 min), which appears when Detail is selected.
