A vague, short answer to a vague, short question: snmpd is probably not automatically starting during the server startup. Start snmpd at the server you are trying to graph.

JP is right; mrtg's usual response to "i can't get any new data" is "i'll keep on graphing the last data i did get", leading to straight-line graphs. check that mrtg can in fact get up-to-date data from the device(s) in question, and if it can't, fix it. –  MadHatter Oct 29 '10 at 11:01
