Setting the Real Time Tab Options
Setting Options in the Sniffer Window
Use the options in the Tools > Options > Real Time tab to enable and
set options for the Sniffer’s real-time decodes feature.
See Enabling and Setting Real-time Decodes on page 213 for details on
using the options in this tab.
Setting the MAC Threshold Tab Options
Use the Tools > Options > MAC Threshold tab to set alarm thresholds
for each of the dials on the Dashboard as well as many other network
statistics. If the value sampled for a particular statistic exceeds the
threshold over the specified Monitor sampling interval, an entry is
made in the alarm log. You can monitor the alarm log to keep watch over
your network.
The MAC Threshold tab lists various network parameters that can
trigger a threshold alarm. The exact parameters depend on the currently
selected adapter.
The High Threshold value for each measure will be the average per
second value measured during the monitor sampling interval. Specify
the interval at the bottom of the dialog box and click OK.
