An NDA is only needed to look at data in prod as "some' of eventlogging data is of private nature.
An alternative to accessing this data is to create some aggregate reports on top of the non-private data. I can help with all of this, including making the repository, configuration, crons, and some sample queries. I do this for anyone that needs it at WMF. I'm happy to do it for anyone reporting on event logging data in general, because that keeps all jobs in a similar format and makes any maintenance or migration of those jobs easier.
If you'd like to do this, just ping me on email here or IRC: milimetric
