keep all historical data (even data polled every one miniute

[haaaany]

Hi,
i'm plotting the traffic of my customer and i need to charge him based on traffic quota so i need to pull traffic every minutes and keep these data for at least one month. how to accomplish this in cacti.
usually the cacti will average these values every day and every month but i need to keep the 1 minute data history

noting that i just installed a fresh CactiEZ

There are five things that need to change to support one minute polling in the 0.8.8 branch.

1) Change step from 300 to 60 (update data_template_date set rrd_step=60 where rrd_step=300)
2) Change all the RRA settings to keep the right amount of data (need a calculator, and understanding of RRDtool)
3) Change the Cacti Polling interval to 60 seconds
4) Repopulate the Poller Cache
4) Remove all existing RRDfiles as they are built based upon 300 second update.

Cacti 1.0 development on Github makes this much easier.
