Predefined event handlers
FortiAnalyzer includes many predefined event handlers that you can use to generate events. You can easily create a custom event handler by cloning a predefined event handler and customizing its settings. See Cloning event handlers.
If you wish to recieve notifications from a pedefined event handler, configure a notification profile and assign it to the event handler. See Creating notification profiles.
|
In 6.2.0 and up, predefined event handlers have been consolidated and have multiple rules that can be enabled or disabled individually. |
To view predefined event handlers in the FortiAnalyzer GUI, go to FortiSoC/Incidents & Events > Handlers > Event Handler List. From the More dropdown, select Show Predefined.
The following are a small sample of FortiAnalyzer predefined event handlers.

FortiOS system events
FortiOS predefined system event handlers are consolidated into a single event handler with multiple rules called Default FOS System Events.
Events are organized by device in the FortiSoC/Incidents & Events dashboards, which can be expanded to view all related events.
Default FOS System Events rules apply tags to each event, allowing you to identify which Default FOS System Events rule triggered the event.
|
If you are upgrading from a version before FortiAnalyzer 6.2.0, the existing legacy predefined handlers which are enabled or have been modified will be available as custom handlers. In the Event Handler List, select the More dropdown and choose Show Custom. |
