[mrtg] Re: rrd file size to store 5-min data for 1 yr

[Heath Deschenes]

I am interested in setting this up. 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. 

Thank you for any assistance, 
Heath

See how useful proper quoting is?

1) Removed all irrelevant lines
2) Moved your lines to the place where they belong
3) Easely spotted:  1000 interfaces and 5 minute resolution for an entire
year

Much of what looks like rudeness in hacker circles is not intended to give

communications style that is natural to people who are more concerned about
solving problems than making others feel warm and fuzzy.
