Well, you could always RTFM (meant in the friendliest possible way). http://people.ee.ethz.ch/~oetiker/webtools/rrdtool/manual/rrdresize.html
The basic command is rrdtool resize filename rra-num GROW|SHRINK rows To store 5 minute data for one year would require 366 * 24 * 12 = 105408 rows. I believe the "normal" rrd created by mrtg has 800 rows, so you would want to grow by 104608. This will result in rrd files around 12 MB. If you just want to create new rrd files of any arbitrary size, instead of expanding existing ones, mrtg can do this for you automatically. See http://people.ee.ethz.ch/~oetiker/webtools/mrtg/reference.html#rrdrowcou nt How the graph would look depends on what front end you are using to generate the graphs. Some front ends may allow you to change the number of data points that are graphed interactively or through a cgi parameter, or you could always modify the script to generate whatever graphs you want.

I have looked around and not found much information about setting up RRD to store 5-min data for 1yr or 2yr. Can someone please point me to a location that discuss' the setup for this? Also what does the graph look like then? I only monitor about 100 interfaces so the file size will not be a problem for me.
