Found a simple SNMP trap receiver for windows that writes traps to a file for Splunk.

After many hours spent with SNMP modular input and Net-SNMP with little to no success, found this app. Simple. Elegant. And so far haven't had to install any custom MIBs, which were giving me lots of trouble trying to implement in the other options.
It's free, and considering how long I spent troubleshooting totally worth sending a donation to the developer. Wish I had known about this months ago. Haven't worked with the data in Splunk yet. Time will tell if this is an effective solution. Even if the app isn't used for ingesting into Splunk, it's a great way to see OIDs.

Hope this helps someone else.

The output log file includes the description in a pipe | delimited file, so very easy to parse with splunk.

You can see the associated OIDs and even raw data. Not in the log file but in the window of the app.
