Once you do this..
What happens to mrtg does it not care and just keep logging leaving
the the averaging of the yearly data to rrd ?

Can the same be applied to daily.. ?
Ie would like to keep every 5 minute collection for 2 years.
( I got the disk space, not the patience for management asking
why they cant see the daily results for 2 weeks ago ).

Perhaps someone who has done this wouldnt mind posting commands /
examples of disk space after they have done the same.

Thanks again.
