You can monitor all types of event logs from FortiGate devices in Log View > FortiGate > Event > All Types. This dashboard displays the total counts for event logs by type, name, and level. You can filter the dashboard by FortiGate device(s) and time frame for the event logs.
The Total Events widget on this dashboard displays a line chart of event logs by level. You can hover your cursor over the line chart to display a summary of the count and time at that point.
The other widgets on this dashboard list the event names for the displayed event types. These widgets can be toggled on/off from the Toggle Widgets dropdown. By clicking an event name in the widget, you can open a list view of those event logs filtered by the devices and time frame you selected on the dashboard.
