I apologize for the confusion here, but the
https://github.com/edx/insights repository is actually an early prototype and is not the code that we currently run in production. Instead we have been using the following repositories:
The code in those repositories is what we run in production and is what generates the screenshots you see in the docs.
Note that these repositories are also not yet well documented and difficult to setup (particularly edx-analytics-pipeline). There are a couple of setup guides on the wiki
https://github.com/edx/edx-analytics-pipeline/wiki/, however, I'm not aware of anyone actually attempting to set up the pipeline using just the wiki. There are probably some incorrect and/or confusing instructions in there.
We prioritized open sourcing the code, but have not yet taken on the effort necessary to make it easy to use. It currently requires quite a bit of technical expertise, code reading and manual work to set it up. That said - if you are willing to take on the project, we would love to know how it goes so that we can help identify the most important pieces of missing documentation etc. We are happy to answer questions on IRC or on this list as issues come up.
Thanks,
