The output was fine... Apparently "0" always becomes "undef". The reason my graphs weren't showing anything was that I had at some point in my tinkering removed the "gauge" option. So mrtg was just sitting there waiting for the number to increment (which it really won't by more than a digit or two). All is well now. That "undef" thing was really throwing me as I was interpreting that as "your script fed me something I can't parse". I tested with a simpler script that just spit out two digits, and that showed me what was going on.
