Figure 3–14: Performance View
When the Performance View opens, no port statistics or errors display. Each port bar
graph in the upper portion of the view displays the instantaneous transmit or receive
activity level for the port, and is updated every five seconds. The relative value
displayed is the greater of either the transmit or receive activity (whichever value is
greatest when sampled). Each port’s graph has multiple green-bar level indicators that
correspond to a percentage of the maximum Fibre Channel throughput for the port
(either transmit or receive). If any activity is detected for a port, at least one green bar
displays.
A red indicator on each port bar graph (high-water mark) remains at the highest level
the graph has reached since the Performance View was opened. The indicator does
not display if the port is offline, and is reset to the bottom of the graph if the port
detects a loss of light.
When the mouse cursor is passed over a port bar graph, the graph highlights with a
blue border and an information pop-up displays adjacent to the port as follows:
• If a device is not attached to the port, the pop-up displays the port’s current state.
• If a device is attached to the port, the pop-up displays the WWN of the attached
device.
