1. Storage engines used
2. Optimizer switches - how many use default, how many don't (and whats on)
3. Query cache on/off? (got to be careful here when displaying - we have it as ON with 0 allocated size so its effectively disabled)
4. Is threadpool enabled?

I'm sure others will come up with other interesting bits, but as I said, this is just to satisfy general curiosity and to see how our features are being used in the wild (and if they're not, maybe making more content to draw users into it)
