Russell, Cacti is pretty SNMP-centric, but in our environment that is about all we are using it for anyway. I'm no cacti expert, but to me, that's the beauty of it - I don't really know the inner workings of cacti, and I am not a programmer or scripter, but I got it up and running pretty quickly. I'm not sure if you would call it autodiscovery, but cacti does do an snmpwalk on the devices that you specify, and the pre-built data collection methods that come with it are designed for getting snmp interface statistics. You can, of course, add other data collection methods, but out of the box, it is basically an interface traffic grapher. You still have to manually input each device that you will collect data for. Once you have specified the basic host information, it gives you a table showing all of the interfaces on that device and a checkbox for each item that can be graphed. To be fair, though (and this applies to nagios as well as cacti) most of the effort you put in to setting up a monitoring solution is a one-time thing. It takes time to input all of the devices, but for the most part once the devices to be monitored are specified, that work is over. I think people incorrectly place a lot of emphasis on this or that product's autodiscovery function. Cacti's interface makes it really easy to maintain the configuration, and I think that is a bigger win than autodiscovery. What do you mean by new device types?
