Where did you get "--start N" from ? Why those "...GE:60:..." ? > > rrdtool update chatter.rrd N:$packets:$bytes Using "N:" every 60 seconds _approximately_ together with a heartbeat of 60 ??? Where did you get this idea? For all of the above comments: I am _not_ saying it is wrong per se. But you should be able to defend your choices. If you cannot, it is because you did not understand what you are asking rrdtool to do. And thus rrdtool may be doing something different than you expect. This in turn may very well be why you do not get the results you expect. > Whenever I try to generate a graph, with the following for example: > > > rrdtool graph chatter.png -t "ResNet Chatter Data" > > DEF:Packets=chatter.rrd:packets:AVERAGE > > I get the "0x0" "I'm not playing" message, and no graph. When I use You are _not_ creating a graph. That is not because something goes wrong, unless you consider the problem between keyboard and chair. Compare your command against any(!) of the examples creating images. > I've been poking away at this for hours and I can't figure out what's > wrong - why the data isn't going in.
