Carter, 

The value I'm after is based on 5 minute samples of user uploads (inbound traffic) that are sorted highest to lowest then the value at the 95th percent point is then used for our volume calculation. Is their a way to pull the 5 minutes samples like "ragraph -M 5m" using the text "ra" tools? 
I just see the rrdgraph is able to do it but not sure yet how to use it.
