Cacti and MRTG both have support for rrdtool backends. How the rrd is processed 
is up to you. A simple script to poll data and do some basic math and email the 
results, or generate a graph. Cacti has several plugins for sending reports. 
MRTG users tend to just script additionals. It's not as gui oriented as cacti, IMO.

Each has pros and cons. If you have a sound internal php/mysql setup, cacti is a 
breeze and the plugin php scripts are cute for the non-techies.
