Using a FortiAnalyzer in a security fabric allows you to simplify network logging by storing and displaying all log information in one place.
Currently, FortiAnalyzer does not have any security fabric specific features. However, you can configure all of the FortiGates in the security fabric to send log messages to your FortiAnalyzer and use its analysis tools on this data.
To add FortiAnalyzer to a fabric, all FortiGates in the fabric must be able to send logs to the FortiAnalyzer. To do this, go to Log & Report > Log Settings and configure Remote Logging and Archiving to send logs to the FortiAnalyzer.
