For the last several months, I’ve been helping Concurrent design and build Driven, their application and performance monitoring tool for Cascading. The application includes some interesting live data visualizations that tell you about the structure and performance of Cascading applications as (and after) they run on the cluster.

Driven went into public beta last week, so I can now show what the application looks like:

The directed graph above shows the functional composition (similar to a query plan) of a cascading app, and the table at the bottom includes timing information for the executable components of the app.
