Yes, PNP is, IME, the way to go.  It's not too heavy, but if you need
to spare some cpu cycles on the Nagios server, consider using batch
mode and ship the data off to a second server for processing.

There are some powerful tools around for extracting and manipulating
the data from the .rrd databases too.  In particular look at rrdexport
( http://www.mrtg.org/rrdtool/doc/rrdxport.en.html ) for extracting
the data so you can manipulate it in Excel and drraw (
http://web.taranis.org/drraw/ ) for combining many metrics in to one
graph and manipulating the data using rpn.  See
http://www.semintelligent.com/blog/articles/39/pnp-aware-version-of-drraw-released
too for a version of drraw customised to make best use of PNP.
