Okay I'm pulling my hair out here. I'm playing around with Windows Defender Events, trying to capture them and get them in with CIM compliance. I've looked the TA on splunkbase but it's not working so I started extracting pieces to see what is going on. I have the event log (WinEventLog://Microsoft-Windows-Windows Defender/Operational) events being ingested and identified but my EVALS in the props.conf aren't getting through to search.
Here is a list of things I've looked at
btool check- syntax is correct
btool props list "WinEventLog:Microsoft-Windows-Windows Defender/Operational" --debugthis shows all the EVALs that I'm expecting, including some static values I put in for testing
So a static EVAL (not a calculated one from a potentially missing field) shows in props, shows in the Calculated Fields list, but DOES NOT show up in a search. I feel like I'm missing something obvious and it's going to be a duh moment but I can't determine what I'm missing.
Do you have the actual EVAL statement? If an EVAL is applied, but doesn't actually evaluate out because of a no match/the logic doesn't function as expected, then you wouldn't see anything in your results.
If the EVAL is sensitive, can you post a sanitised version of it?
@martynoconnor So I've removed most of the EVALs and have a single static value one configured. Here is the btool props list for the sourcetype, notice the single eval (EVAL-brenden) from TA-windefender/local/props.conf.

My props.conf looks like so:
[WinEventLog:Microsoft-Windows-Windows Defender/Operational] EVAL-brenden = "brenden"
And I found the answer, I needed to change the props.conf entry for that source from
Now everything is working. I knew it was a "duh" issue.
