The Active Reports section allows you to choose a report type and how you would like the graph contained within the report displayed, as a pie chart or bar graph. You can view the report by clicking in the icon of a pie chart or a bar graph and the associated report will be displayed.
The report may take a few moments to be displayed since these numbers are gathered and the reported being generated when you click on the icon.
Once the report is displayed you will see the report type along with the time period the report covers followed by the graph and a breakdown of each item in the graph. Each highlighted item in the graph can be clicked on to view details concerning that item.
For example, if Attacks by Alert Class was chosen, a graph displaying the different protocols will be displayed. In the example above, if Information Leak was chosen, all the source hosts attempting this exploit in to the Information Leak alert class will be displayed in detail.
This works for all the graphs in this section.
