Dashboard Widgets
By default, the Dashboard displays widgets in a Layout of 3 Columns but you can customize the Dashboard to display only 2 Columns, instead.
You can also decide which widgets to display or hide so that you see only those you want to monitor. To display a widget, select a widget category from the Widgets drop-down and select a widget to add it to the Dashboard (widget names that appear in faded grayed-out text are already displayed). Hide (stop displaying) a widget by closing the widget ( in the widget header). The firewalls and Panorama save your widget display settings across logins (separately for each administrator).
Refer to the Last updated timestamp to determine when the Dashboard data was last refreshed. You can manually refresh the entire Dashboard ( in the top right corner of the Dashboard) or you can refresh individual widgets ( within each widget header). Use the unlabeled drop-down next to the manual Dashboard refresh option ( ) to select the automatic refresh interval for the entire Dashboard (in minutes): 1 min, 2 mins, or 5 mins; to disable automatic refresh for the entire Dashboard, select Manual.
