Well, you'll may have problems with different numbers of temperature probes on 
different models etc. so if you use NCV, and push multiple values into one 
rrd, you will need multiple, differing graph definitions, and have have 
problems selecting the right graph definition.

The devmon collector (either the c module for Hobbit, or the perl one to run 
as an extra script with hobbitd_rrd) results in one rrd file per probe, 
making this much simpler.

(I don't have many Dells, most are 1750s, but I see a lot of problems with the 
HP ProLiants, the DL380s have 5 probes, the DL580s have 7).

How is that different to IPMI (which is also UDP).

Good luck with the graphs.
