Line Chart and Time Slider
The line chart shows the event happened on the appliance during the selected time span in a two dimensional graph,
in which the x-axis shows the time interval and the y-axis shows the number of occurrences. A coloured line connects
events of the same type.
Hint: Different types of event are denoted with different colours.
The time slider is located underneath the chart and allows, within the selected time span, a more fine-grained view of the
events, depicted here as histograms. Indeed, the two grey handles on the left and right limits of the slider can be clicked
and dragged to reduce the time span shown in the line chart. When reduced, the slider can also be moved by clicking in
its middle and dragging it to the left or the right.
Summary Grid
The summary grid has a twofold purpose: On the one hand to show the number of occurrences of the various types of
events that took place on the appliance in the selected period, whereas on the other end to filter which type of events
are shown in the line chart. Its content changes according to the tabs it is located, i.e., to the types of events logged. The
summary grid is not present in the Mail, Attacks, and Virus tabs, in which is replaced by a number of tables with details
about the events.
Pie Chart
The pie chart diagram shows graphically the number of event that took place in the selected time span. When in the
Summary tab, each slice can be clicked, to open the tab corresponding to the type of event and show a more detailed
representation.
Syslog Table
A table that shows the syslog messages extracted from the log files and related to the events shown in the charts. When
the table carries lot of messages, these are divided into many pages and can be browsed using the buttons and number
at its left bottom. At the right bottom there is an icon that allows to refresh the table’s content.
8.1.2 Summary
The Summary tab gives an overview of all categories of events recorded on the appliance. The summary grid allows to

The System tab displays all events that are related to the system efficiency and to system administration. These are all
the events shown:
▪ Uplink (Red). The times the uplink(s) went online or offline.

A click on the small icon on the left-hand side of each event category causes the other categories to not be shown, while
the current is further detailed and the pie chart is updated.
