Configure ELA to receive SEPM logs

Per the website it states "Collects logs from heterogeneous sources (Windows systems, Unix/Linux systems, Applications, Databases, Routers, Switches and other Syslog devices) at a centralized location".

Per PCI 5.2.d, I have to retain AV software logs. I'm looking around and do not see how to set ELA as the external syslog server. I already have an agent installed on my SEPM server collecting the Windows logs. Any idea as to how to set this up correctly?

I understand that SEPM backs up the logs, and they are available for 90 days prior to archival, but the problem is the backup location is on the C:\ drive by default and you can't change that w/out moving the entire Data folder to another drive. This would entail providing another VHD for my VM to use and I would rather just have ELA handle the retention since I have it set up for PCI compliance anyway. This way all my PCI logs are in one place. I can always check SEPM for the first 90 days, then ELA for the other 9 months.
