URL Logging - How/where to find the URL logs

In the new firmware 6.3.1 how to configure Log server Host and where to find the url logs .??

You need to setup an external syslog server and here is more info:

We use Log Center on a Synology server.
Works very nicely both remotely and locally as long as you don’t have the Server on a SpeedFusion tunnel and want to accept logs from clients on the same SpeedFusion tunnel but have layer 3 isolation enabled!
