Hi [NAME], You're talking about the SIEM\Syslog settings under Management > Services Management > Events Management correct? If so this configuration deals with events captured by our Advanced Threat Protection \ Dell Endpoint Security Suite Enterprise (ESSE) solution.  If you have that solution deployed events should start feeding into your SIEM\Syslog going forward.  If you do not have that solution deployed in your environment no other Dell Security Management Server events will be sent over.
I'm running the virtual appliance for Dell Security Management Server version 10.2.14. I have configured Events Management for  "export to syslog" via tcp/514  and have tried both an ip address and fqdn to no avail.   I've confirmed that i can reach the SIEM system on tcp/514 so that's not the issue.  What else do I need to do to have the logs sent to a remote syslog server?
