Monitoring Network Traffic
Using Traffic Monitor
To change your threshold settings, select a network type such as Ethernet.
The threshold values for the attributes for Ethernet segments are displayed.
You can either move the sliders to the left or right to increase or decrease a
threshold value, or click on the up/down controls underneath the sliders to
fine tune the threshold values. As you move the sliders, these values will
change accordingly. To save your changes, click on
Apply at the bottom of the
Threshold window. The changes are applied to all segments of that type, for
example, all Ethernet segments. When you are finished making changes, click
on
OK to exit the window.
N o t e If you click on OK, any changes that you have made and not yet applied will
be applied. If you click on Cancel, any changes that haven't been applied are
not applied. If you have applied changes before clicking on Cancel, those
changes remain applied.
If you want to change the thresholds for a single segment, select the Segments
tab at the top of the window. Select a segment from the list box. The
Thresholds window now reflects the attribute threshold values for that
segment. Click on
Apply to save any changes.
N o t e If you select a different segment from the list box before you have applied
your changes, a message will appear asking you if you want to apply your
changes.
Initially, default values are in effect for all segment types. The Defaults button
returns the threshold values for that segment or segment speed to the original
default values.
N o t e Traffic Monitor will send a trap to the configured trap receivers when a
threshold has been exceeded. The Traffic Monitor page does not need to be
open for Thresholds traps to be sent.
Displaying the Network Meter
The Network Meter provides an “at-a-glance” look at the most severe traffic
problem on the network being monitored during the current minute. To launch
the Network Meter, click on the
Net Meter button below the histogram on the
Traffic Monitor page. Clicking on the Show Worst 5 Segments button displays
a window showing the top five thresholds that have been exceeded and the
associated segments.
