On a GAIA system, like and MDS, you have the option to send Syslog directly to the syslog server.
That being said, here is why you will not get the syslog information from the MDS into any Syslog Forwarder stream:
All syslog forwarders are connected to a specific domain, the MDS itself is not, if it will forward the syslog to a CP domain it will most probably be the Global domain. So when you have a forwarder on the global domain, I really don't know what you will get, all logs for all domains or only these syslogs?
