Did some searching on my own. Looks like in the NCM settings there are 2 settings that allow you to see what's going on. "Scheduled Jobs" and "Inventory Monitor". Both of them produce logfiles in the "C:\Program Files (x86)\Solarwinds\Orion\NCM\Logging" directory.
The Inventory Monitor I think goes in the "General.log" and produces tons of output, actual output of every SNMP query. Thinking turning this off might be a good idea right now, although potentially useful. Just generating tons of output.
The "Scheduled Jobs" generates a "Job-<JOB NAME>.log" file. In that is a fairly minimal status of the job. But, it is telling me things like failure reasons for why nodes aren't responding to SNMP queries and such. Will try and sort that stuff out before I try getting into the other log file...
