Alright ... thanks guys.
I think that I might just try running a separate copy of Smokeping on
another box for a little while, and see how all of that actually pans
out looking at the two configurations side by side.
Hopefully then I'll actually be able to SEE what sort of differences
it's going to bring [both good and bad I guess] ... which means that
I've [hopefully] got a much better chance of actually understanding it
all properly. ;)
Thanks again for your help everyone!
