What happened to this app, I remember this only a few months ago, now it appears to be gone.
It's back now..
Puppet Enterprise App for Splunk - looks like something went wrong.. 404 page not found.

Oops!
404 Error: Page not found.
If you think there is something wrong with Splunkbase, please let us know.
also, there is a "Splunk App for Puppet"
https://splunkbase.splunk.com/app/1701/
This isn't an answer...
I know it's 404 that is why I posted where did it go.
The other puppet app is really old and not compatible with current puppet. Splunk and Puppet had a big press release about it back in April of 2016...
