Fortianalyzer in collector mode

"log forwarding" option is not there under System setting. I tried to configure " set show log-forwarding enable" but command is not available on CLI.

hostname $ config system admin setting (setting)$ set access-banner Enable/disable access banner. admin-https-redirect Enable/disable redirection of HTTP admin traffic to HTTPS. admin-login-max Maximum number admin users logged in at one time (1 - 256). admin_server_cert HTTPS & Web Service server certificate. banner-message Banner message. http_port HTTP port. https_port HTTPS port. idle_timeout Idle timeout (1 - 480 min). show-add-multiple Show add multiple button. show-checkbox-in-table Show checkboxs in tables on GUI. show-device-import-export Enable/disable import/export of ADOM, device, and group lists. unreg_dev_opt Action to take when unregistered device connects to FortiAnalyzer. webadmin_language Web admin language.

Please let me how I can verify the Analyzer IP configuration on FAZ (acting as collector). Also, how i can enable to "log forwarding" option on gui?
