Hi João

Thanks for sharing.

Dalmatiner was the first one I googled, and I even watched the author's
video.

In my case, i just need to plot VM metrics, nothing else. Moreover, it
relies on ZFS and has a couple of deps (see rebar.config).

As i've explained in the beginning, I'm an Erlang newbie and I'm looking
for simplicity first.

Thanks again anyway. I'm sure some others will have more interest on
Dalmatiner than I. Benchs we're very impressive.
