Might be of interest to some of you: I export my logs to Sumologic. To help with reporting I created a lookup table (CSV file) so I could translate log event type codes to something user friendly. I should automate this with a script but for now the table is maintained manually, and I just recently updated it.
I also submitted a feature request to Auth0 asking them to provide & maintain something equivalent.
