Thanks for sharing! How do you interpret those graphs? How do you know when the user experience is slow or when the server is maxxed out?

From my experience looking at those graphs, I see that the iorate is pretty low and that the cpu is almost idle. Checking "top", I see that the RAM was sufficient, as there were almost no swap use.

I also use chartbeat.com to see how the users are interacting with the site in realtime. They provide also two useful metrics: user load time and server load time. Looking at those, I can see that the user experience is pretty good, and that the server is up and responding very quickly.
