The log storage policy affects the logs and SQL database of the device associated with the log storage policy.
If you change log storage settings, the new date ranges affect Analytics and Archive logs currently in the FortiAnalyzer device. Depending on the date change, Analytics logs might be purged from the database, Archive logs might be added back to the database, and Archive logs outside the date range might be deleted.
To configure log storage settings:
- Go to System Settings > Storage Info.
- Double-click on an ADOM, right-click on an ADOM and then select Edit from the menu, or select the ADOM then click Edit in the toolbar. Scroll to the log storage policy sections at the bottom of the Edit Log Storage Policy pane.
