Monitor Screen Events

You are here: Monitor > Events > Screen.

Use screen events to view the information about security events based on screen profiles. Analyzing screen logs yields information such as attack name, action taken, source of an attack, and destination of an attack.

You can select either the Grid View tab or the Chart View tab to view your data:

Grid View—View the comprehensive details of all screen events in a tabular format that includes sortable columns. You can group the events using the Group By option. For example, you can group the events based on source country. The table includes information such as the event name, source country, source address, destination country, attack name, and so on. Table 35 describes the fields on the Grid View page.
Chart View—View a brief summary of all the screen events in your network. The top of the page has a swim lane graph of all the screen events. You can use the widgets at the bottom of the page to view critical information such as, top screen attackers, top screen victims, and top screen hits. Table 36 describes the widgets on the Chart View page.
