(I'm one of the cofounders)
I got graphite going on an Ubuntu installed on my macbook while in the air between SFO and ATL.
Literally, discovered it, downloaded it, and graphing metrics before we landed.
Now, that was, I think, in 2010. The last time I installed Graphite was a few months ago, and it seems like they have split the project up a bit. It took a bit longer.
