The Historical Traffic Monitor Window
8
LICENSED MATERIAL - PROPERTY OF FUJITSU SOFTWARE TECHNOLOGY CORPORATION
The port gauges on the Hub window, Switch window, and Historical Traffic Monitor
window measure port traffic differently depending on the device; switch gauges
display a rate while hub gauges display a percentage. The rate displayed by switch
gauges is a MB/second baud rate corresponding to both received and transmitted data
on the port. The percentage displayed by hub gauges is a portion of bandwidth
corresponding to the port’s received data only (the percentage is calculated by the
hub’s firmware as a port percentage of the loop’s total bandwidth).
This performance monitoring feature can be used to determine the bandwidth used on
the device’s loop. Monitoring the bandwidth usage allows you to make informed
decisions about the need to add devices or implement switches for increased
throughput.
 NOTE:
The poll interval for traffic data is five seconds and is not affected by the Softek
SANView poll interval set through Softek SANView’s Tools menu.
You can set the port traffic threshold (rate or percentage) for triggering the Attention
and/or Overload states. Every time this threshold is exceeded, an event is recorded in
the SAN Events frame; and the appropriate icon (Attention or Overload) appears in
the Historical Traffic Monitor window above, ports that exceed the thresholds. For
Vixel Switches, thresholds correlate to the amount of port traffic—the selected point
between 0 and 200 MB/second. For Vixel Managed Hubs, thresholds correlate to the
percentage of available traffic used by the port—the selected point between 0 and 100
percent. (You can select a single percentage point by pressing an arrow key.)
The File menu allows you to close the window or exit the SANView Client.
The Options menu allows you to reset traffic threshold settings for either all Vixel
Managed Hubs or all Vixel Switches (depending on the window from which the
Historical Traffic Monitor window was opened).
The Tools menu allows you to change traffic threshold settings for either all Vixel
Managed Hubs or all Vixel Switches (depending on the window from which the
Historical Traffic Monitor window was opened).
The Help menu contains two options: Contents for online help display and About
Softek SANView... for system and version information.
The Historical Traffic Monitor window also offers the following information:
• Traffic display for total of all ports.
• Traffic display for all selected ports.
• For Vixel Managed Hubs, traffic display for all selected zones (by port).
• For Vixel Switches, a separate measure of port receiver and port transmitter traffic
(left and right numbers under port graphs, respectively).
• Time Scale by the selected unit (seconds, minutes, or hours).
