I factored out the sample outputs and used an include to pull
in that content.
In the future, we could automate creating those sample data files
based on the live instance, however, it will need some thought
as many metrics are instantiated dynamically. That means that
simply launching the server to dump the initial counters could
miss a large number of the main production counters that are
the most interesting. Likely we'll need something smarter than
that approach. But that is an issue for the future!
