I asked Ben to update that document with the following :

There are 2 kind of needs for perfparse.
1/ need to see what happened yesterday, of few days ago, on a graph, and =
only thanks to
a graph. There is a storage module that allows an export of data into a f=
ormat friendly
to gnuplot. This should fit most of your needs already.
If somebody implements a storage module for rrdtool, this should not be t=
oo hard to do,
and it should also fit that need : fill the RRD database, and use your ow=
n tools to ask
rrdtool to make the graph.

2/ need to store data for long-term, and then make statistics and reports=
 (including
graphs). You must use a database for that. There is no way to use a rrd f=
ile. Ben
explains this well in his FAQ.

In other words, Ben and many will be very happy with a rrd storage module=
 is somebody
wants to contribute. But it will not replace the database.

Last thing : one of the latest version of Perfparse I contributed to (0.1=
04.8 or 0.104.9
?) allows to compile with no database support. With no database support, =
you get only
20% of the features of perfparse. With RRD support, those 20% would be re=
ally more
friendly than now.
