[rtg] Traffic is wrapping

We hit the limits of scalability of RTG somewhere around 200,000 targets
on 2500 devices at a 5 minute polling cycle. And RTG wasn't the problem
per se, but when each target is a seperate UDP connection, and a
seperate write to the database, firewalls and database boxes have a
tough time keeping up. Our configuation is also a little atypical as our
targets are scattered all over the world.

yrtg looks interesting... didn't know it existed.

Does anyone know if anyone has tried to tackle a pgsql implementation
with any success?

Out of curiosity, at what point (say, interface count) does scalability
start to become an issue? Right now I monitor 30 FE interfaces across 2
routers (7600 series) with 5 minute polling - and haven't noticed any
problems. Will I start to see some soon or is scalability problem much
higher in the interface/device count range?

Thanks
John
