Enable System Logs on FortiGate | BLËSK Network Monitoring

You’ll need to go in via the CLI as they have removed this option from the GUI as of FortiOS v5.0, then enter the following commands to enable and configure system log messages to be exported to your BLËSK server.

config global
config log syslogd setting
    set status enable
    set server [ip.or.dns-name.here]
    set port 513
end

To set the level of messages you want to see (optional).
