I'm wondering if we could try using bootstrap.js and bootstrap.css as much as possible to match the aesthetics of the rest of the application.  This all looks fine, but it could look even "finer" with the bootstrap.css.  Like for each of the green sections, you could make them use the ``btn-success`` class if they're passing or ``btn-warning`` if they're failing.  I think ``btn-small`` or ``btn-mini`` would set the size about where you need it.  http://twitter.github.io/bootstrap/base-css.html#buttons

and perhaps there could be some sort of box around the log data itself on the right side?

Your layout looks like it's working fine, but perhaps we could make use of bootstrap's fluid-grid system?  Just a thought:
