Site Summary
Note To change from bytes to bits, choose Administration > System > Preferences and change
the “Data displayed in” selection.
Site Summary
The Site Summary Dashboard (accessed by choosing Monitor > Overview > Site Summary) will show
you information about the sites in your network. You can use the Interactive Report on the left side of
the screen to change the information displayed. For more information about sites, see Sites, page 2-58.
The charts displayed on the Alarm Summary dashboard are:
• Top N Site Pairs by Traffic
This chart shows top site to site traffic.
• Top N Sites by Average Transaction Time
This chart shows the average transaction time by site.
• Top N Sites by Traffic
This chart shows the sites that have the most traffic (which are the most active). It is a total of all
the traffic sent or received for hosts that belong to the particular site, which means that this traffic
includes intra-site traffic as well.
• Top N Sites by Average MOS
This chart shows sites that have the highest average Mean Opinion Score (MOS).
MOS will normally range from 1-5, denoting the perceived quality of the transmission, where 1 is
the lowest perceived quality, and 5 is the highest perceived quality measurement. The MOS is
weighted depending on the duration.
To see any of the charts in table format, use the “View as Chart / View as Grid” toggle button on the
bottom right corner of the chart. You can also click the “View as Image” button to view the image and
save it as a PNG file. The numbers will be formatted according to what you have configured in
Administration > Settings > Preferences.
Alarm Summary
The Alarm Summary Dashboard (accessed by choosing Monitor > Overview > Alarm Summary) will
show you the top alarms occurring in the network.
To display network traffic information for a particular amount of time, use the Interactive Report on the
left side of the screen. The Severity Selector in the Interactive Report allows you to choose to view high
severity alarms only, low severity alarms only, or both high and low severity alarms (these settings are
configured under Setup > Alarms > Thresholds). You can also choose the desired amount of time from
the Time Range drop-down menu, or you can customize the time range.
On any chart on the Alarm Summary Dashboard, you can click on a colored bar to see the Context menu,
with which you can get more information.
If you do not set any alarms or thresholds, the Alarm Summary Dashboard will have no data. For
information on setting up alarms and thresholds, see Alarms, page 2-36.
