I’m probably very late to this party, but I just discovered Dashboard Spy. Given the amount of “data porn” that folks in webops look at on a daily basis, this sort of stuff is pretty damn interesting.
I’m especially loving the current trend of developing ‘business’ dashboards, since it can fit in quite nicely with infrastructure statistics. Quite often when I need to make capacity justifications, I pull forecasts from both the higher-level metrics (i.e. photos uploaded) and the lower-level metrics (i.e. disk space consumed by photos) and have to marry those two bits together.
In fact, I love that stuff so much that I’m writing a book about it.
