You presumably are interested in the detailed (daily) graph for a date 3 months in the past? This data is normally expired by RRD after a week or two, so you need some way to preserve it and some way to display it. To preserve it, you can either modify the .rrd file to have a much, much longer retention period, or you can make a daily archive of the .rrd files. Both cases will require a substantial amount more disk space, as you are storing about 12 times as much data. To display it, you will need to either write your own display utility, or use one which can cope with archived or extended rrd files. (biased advice coming) You can do this using routers2 as your frontend for MRTG/RRD. If you enable 'RRD archiving' (this requires a nightly job to archive the .rrd files and expire old archives) then you will get an additional date dropdown in the frontend so that you can display graphs for archived data. Instructions are in the doc/HOWTO file distributed with routers2. We use this here to archive daily (5min resolution) for three months, and monthly (2h resolution) for three years.
