These are some user stories I scraped together to help guide the rewrite of ganglia's web application.

Overview
========
Most of the time, I want to just quickly have a look at the overall status of our systems, and verify that everything is 
running smoothly.  I tend to browse around the app, not necessarily looking for anything specific.  I just want to be able 
to see that everything looks 'normal'.  If we receive a problem report (usually something vague like 'the web site is slow'), 
ganglia is often the first place I look for any sign of trouble.

Here, I find the most value in being able to visualize lots of data at once, and in being able to quickly navigate from
