Performance View
Select Performance from the View menu. Figure 11 shows an example of the Performance
View. This view provides a graphical display of performance for all ports. The top portion
of the Performance View displays bar graphs that show the level of transmit/receive
activity for each port. This information updates every five seconds. Each bar graph also
shows the percentage link utilization for the port. A red arrow marks the highest utilization
level reached since the Performance View was opened. If the system detects activity on a
port, it represents minimal activity with at least one bar.
When an end device (node) is logged in to a port, moving the cursor over the port's bar
graph in the Performance View highlights the graph and displays a message with the WWN
of the connected node. If the connected node has more than one port, this is the WWN of
the specific port on the node. When a port is functioning as an expansion port (E_Port), the
message is "E_Port." When a port is not logged into an end-device (not functioning as an
F_Port) or to another director (not functioning as an E_Port), the message is the port's
current online state.
