No. I've been digging into this for a while now and the answer is no. Splunk devs are working on a Sharepoint app, but it's more geared towards Sharepoint administration data (e.g. user activity, failed/successful login activity, etc). I've been working on some Python scripts to pull data directly from Sharepoint with little success, but once I finish I'll share the results up on git or splunkbase.
Here are a couple of things that may help, though:
haufe to pull data from sharepoint lists:
https://pypi.python.org/pypi/haufe.sharepoint
xlrd to pull data from excel (if you have excel data on sharepoint)
link:haufe sharepoint
I have some other python / scripting resources that I've been working on as well. Let me know if you'd like more discussion on the topic. I'd be happy to share anything I have in my quest for a solution.
Other than python scripting, I don't see any automated integration possibilities. Keep bugging Splunk about, it though. It would be great if we could get a solution.
