[tony at specialistdevelopment.com]

Hi Guys,

Im really sorry to ask this as im probably being very stupid...Im new  
to RRD tool and think it is amazing, im trying to write a set of Perl  
scripts to monitor my traffic in and out...

I have followed tutorials, examples etc, but to finally get my head  
around it im trying to do it on my own, but i come unstuck, when it  
comes to RRA's in the RRD creation.

Can anyone explain in really, really simple terms what they are?

Thanks for any replies I get.

Tony
