After further research and talking to the DB admins here, multiple possibilities have come up.
The main factor is your WSUS database embeded, sqlite, or full instance installed?
For my WSUS setup I just went with the embeded database. Below is what pointed us in the right direction, we think. I will be installing SQL tools on the server next week and trying a few things out.

For what I want to do, I think I am going to look to just scrape the data we want out of the WSUS database and put it into a clean report, that WSUS doesnt seem to provide by default.
Sorry I couldnt fully answer your question, but I think the issue at hand is the syslog engine doesnt have access to the logs, and you need to have those logs pulled from the database, or the database provide them by some means.
Hope this helps.
