Out of curiosity, why would you use this? Using a database with
accurate time stamps and log sizing is trivial, and apis for
beautiful html plots are easy to come by.

I haven't played with rrd for over a decade. When it started, it was the
best thing in town. The one thing that rrdtool does that nothing else
typically does is time scaled single charts. So the right side may be in
units of minutes, then step to hours and then to days. This gives you
the short term detail and the long term trends in a single visual. For
looking at network traffic (what it was originally built for) it was
just what was needed.
The other thing about it is that it is well used and robust. Many other
solutions have not had tens of thousands of users feeding data at it.
This means you may up debugging someone's tool to figure out why your
data isn't coming out right. There aren't many sharp corners in rrdtool
at this point.
