[rrd-users] Re: Storimg 5 min data for 2 yr

[Brander, Eric]

After creating the RRD with these parameters, will you then be able to tell
MRTG to use it, and will it then continue to store the 5-minute data?

We do the same thing, except we don't do MAX for the 5-minute data. I'm
not sure that gives you anything since you're polling every five minutes.
The Maximum of one polling interval is whatever you get for that poll. You
can cut your files down to about 3.3MB by getting rid of that.

possible with MRTG, so I will have to use RRDTools. I read basic stuff about
RRD and looks like I would have to do something like this:
