[mrtg] polling every minute but still 5 min avg graph?

[crayola at optonline.net]

Folks, 

I have mrtg/rrdtool/mrtg-rrd.cgi working great 
to obtain and graph CPU and memory stats from 50+
Solaris systems. We are currently running mrtg 
every 5 minutes out of cron to kick off the polling. 
It currently takes about 5-6 seconds to poll all the systems.

The first graph that mrtg-rrd.cgi generates indicates 
that it is based on a 5 minute average, but since we 
are only polling every 5 minutes, its really just the number
returned from the poll (a snapshot view essentially). 

My boss would like me to begin polling every minute with 
mrtg/rrdtool, but still generate graphs using a 5 minute 
average. This would produce a much more accurate graph without 
the headaches that come with trying to physically graph and interpret 5x the 
number of data points. Obviously polling every minute would also 
dramatically increase the number of data points that are averaged 
together to create the other graphs as well. 

Can this be done?   What would I need to modify in mrtg/rrdtool and 
mrtg-rrd.cgi ?

I did see a web page in my travels that explained how to poll every 
minute and get 1 minute avg graphs.. Not quite what I wanted however. 

Thanks for any help you can offer, 
Mike
