[rrd-users] Special Formula Help?

[Wintle, Rod]

I'm wondering if anyone could give me a hand with how to accomplish the
following: 

I have a router interface setup in cacti to poll ever 5 minutes. 
Each hour, I want to roll that 12 x 5 minute values into a average 
Each day, I want to take the 8 largest 1 hour averages (busiest 8 hours)
and create a value that would represent the value for the day. 

The graph that I wish to create would have an X axis that is at the DAY
level and a Y that is bandwidth. 

So, basically, the graph only updates once per day with a value that is
equal to the average utilization for the busiest 8 hours. 

Thoughts? 

Thanks!
