If you enable saving the History notifications when you set up a rule, the history of the alerts and notifications you received is saved in the History table. The history can be useful when analyzing threats by giving you the ability to access this data at any time for analysis. The notifications and history are tracked at a device level. You need to go to theFirewall View of a device to access the History log. You can also export the History log to a CSV file for further analysis.
To access the History log
Navigate to Manager View | Firewalls > Inventory.
Click the firewall for which you want to see the History logs.
