Yes, you can use your FAZ as a syslog server to collect and consolidate logs to a single device. I use mine to collect syslog from about 2 dozen or more (non Fortinet) devices. You would flip the toggle switch on the dashboard to Administrative Domain to allow for multiple ADOMs. One of these ADOMs would be Syslog where any new syslog device, you would add to this Syslog ADOM. You can then also define and tailor your storage needs for that specific ADOM as needed. As an aside, other ADOMs are available to you for logging from other Fortinet products as well like FortiMail, FortiSandbox, FortiWeb, etc... Syslog is the one that is agnostic of the Fortinet brand.
