rrdtool does not replace mrtg but rateup only (the "backend" of mrtg).
rrdtool can log data and draw graphs. Collecting data (e.g. via SNMP or
external scripts) or checking thresholds is not done by rrdtool, you
need another program to do this. E.g. mrtg ;-)

I.e.: mrtg can use rrdtool as it's backend. Read about "UseRRDTool"
(mrtg 2.8.*) or "logformat: rrdtool" (mrtg 2.9.*) on the mrtg
documentation. You will have to use a third program to create web pages,
e.g. contrib/14all or contrib/routers (from mrtg-2.9.* or it's website
http://ukpavu99.adsweu.com/pub/).

Look at the rrdtool website to find other frontends.
