Ah-ha! I'm guessing that you're using MRTG by itself. You may want to look at using RRDTool for the graphing. We use MRTG (w/unknaszero), RRDTool, and 14all.cgi. MRTG runs every 5 minutes and RRDTool stores the data (if there is any, otherwise it stores a 0), 14all.cgi produces the graph whenever we want to see it. This causes "in a way" all graphs to be updated every 5 minutes. When we took an interface down, it reported a flat line until we brought it back up. RRDTool has many features to it and we use several of them. I hope this will help you, it REALLY helped us out alot.
Good Luck!
