How to integrate  to fortigate logs to Cortex data lake.

Does someone know this?

If you use Fortinet Fortigate firewalls, you can still take advantage of Cortex XDR investigation and detection capabilities by forwarding your firewall logs to Cortex XDR. This enables Cortex XDR to examine your network traffic to detect anomalous behavior. Cortex XDR can use Fortinet Fortigate firewall logs as the sole data source, but can also use Fortinet Fortigate firewall logs in conjunction with Palo Alto Networks firewall logs. For additional endpoint context, you can also use Cortex XDR to collect and alert on endpoint data.
As an estimate for initial sizing, note that the average Fortinet Fortigate log size is roughly 1,070 bytes. For proper sizing calculations, test the log sizes and log rates produced by your Fortinet Fortigate firewalls.
As soon as Cortex XDR starts to receive logs, the app can begin analyzing and raising Analytics alerts. Cortex XDR stores Analytics alerts according to your Cortex Data Lake storage retention policy but does not store the Fortinet Fortigate firewall logs. As a result, you cannot query or apply IOC and BIOC rule matching to Fortinet Fortigate firewall logs.
To integrate your logs, you first need to set up an applet in a broker VM within your network to act as a syslog collector. You then configure forwarding on your log devices to send logs to the syslog collector.
