Trying to run it from cmd line first, to eliminate possible IIS/CGI
problems at the very beginning. From same reason tying to limit
> to only mandatory ones. My full command is:
> C:\rrdtool.exe graph graph.png --start=-86400 --end=-300
> DEF:traffic=file.rrd:ds0:AVERAGE

Which has no graph command, so nothing is graphed (as expected).
Please read the manual, or follow the tutorial.  Both can be found on
