For Node Properties, if a node is not logged in, a message is displayed indicating that

node information is not available.

Bar graph display

The Performance view provides a graphical display of performance for all ports. Each bar graph in

the upper portion of the View panel displays the percentage of link utilization for the port. This

information updated every five seconds. A red arrow marks the highest utilization since the opening

of the Performance view. If the system detects activity on a port, it represents minimal activity with

one bar.
When a port is operating as an F_Port and a device is logged on, moving the mouse pointer over

the port’s bar graph displays a message with the attached port’s WWN. If the port is an E_Port, the

message reads

E_Port

. If the port is an FL_Port, the message reads

FL_Port

. If the port is not

logged in, the message displays the port’s current operational state (see

Table 5

on page 71).

Port statistics

To select and display more detailed performance information for a port, click the port’s bar graph.

The bar graph for that port highlights with a darker background, and the lower portion of the

Performance view panel displays the statistics values for the port’s number and the WWN

decoding.
The Statistics Values tables include values for the following categories:

Class 2 statistics

Class 3 statistics

Error statistics

Operational statistics

Traffic statistics

Click a category in the left frame of the statistics area to display only statistics for that category, or

click All to display values for all categories.

NOTE:

There are no thresholds for these values. You may determine that a problem exists by the

rate that the value changes. For example, low BB_Credit can occur if data is sent to a device faster

than it can consume the frames. This can backup into ISLs causing degraded performance.

The Statistics Values tables contain statistics in the following groups. To refresh tables with the latest

data, click Refresh on the upper right portion of the Statistics Values panel or click the port’s bar

graph. Clear all counters for all users using Clear.
