If you are concerned about the impact of mrtg on the machines 
(and with a large mrtg config the impact is significant), then
move the mrtg part to a dedicated (non service impacting) system,
and just run the agents generating the stats on the live systems.

In a previous life I've had a dual processor system pretty much
dedicated to mrtg only - and CPU usage was high... so move the
MRTG grunt work onto a non-important CPU and leave the other CPUs
free for real work - and the occasional statistic generation.
