This app is an experiment in a larger effort to make a Splunk app that builds its own structure and content around the data itself. With the current version you can analyze one sourcetype and index at a time. It will analyze the fields it finds and it will suggest on the order of 50 different reports and visualizations that it thinks you will find interesting. You the user then get to page through several pages of reports run against your data, each paired with appropriate visualizations. If you see any you like or want to investigate further, you can add them to a dashboard, re-run them in another window and.
More dramatically, you can click any element in any of the reports, and this will do what we call Shotgun Drilldown! (Yes it is unusual enough to warrant an exclamation point). The arguments from your click will be interpreted and added to your search and then the shotgun reporting calculations will be repeated on that subset of data, giving different suggestions. Repeat as necessary.
