Switch Statistics
SMON updates these gauges and pie charts in real-time according to the
specified sampling interval. By viewing the relationships among these two
variables, you can learn a lot about the general behavior of the switch.
* Note: If contact with the device is lost, then the graphs will display
the last data received until communications are restored.
Traffic Graph in the Switch Statistics Window
The lower portion of the Switch Statistics window is a traffic graph. The
traffic graph displays selected variables as a line graph, in real-time. To
select the color coded variables you want graphed, use the check boxes
under the traffic graph.
For more information about available traffic variables, refer to the table
below.
SMON continuously monitors statistics for all available Switch Statistics
traffic variables, even those that are not currently selected. For
information on finding the 5 highest peaks of traffic, refer to Appendix A,
Using the Find Top5 Peaks Dialog Box.
The X axis of the graph represents time. The scale on the X axis can be
changed using the
Samples Per Screen field in the Switch Options dialog
box. For more information, refer to Appendix A, Using the General Options
Dialog Box.
The units of the Y axis for all variables are packets. The scale on the Y axis
depends on the maximum value among all of the variables. If the spread
of values is wide, the graphs of variables with small values may not be
visible. In this case, use the logarithmic traffic display to produce better
results (refer to Appendix A, Logarithmic Display).
