[rrd-users] Beginner question: "rrdtool.exe graph" started from windows shell does not produce any graph nor error message

[Petr Lázňovský]

Trying to run rrdtool for first time after few years of life with mrtg. Trying to run it from cmd line first, to eliminate possible IIS/CGI problems at the very beginning. From same reason tying to limit parameters to only mandatory ones. My full command is:

C:\rrdtool.exe graph graph.png --start=-86400 --end=-300 DEF:traffic=file.rrd:ds0:AVERAGE

No graph is produced nor error message is produced, errorlevel is 0, file.rrd was created by mrtg.

Is with rrdtool something like '--debug=' in mrtg? Which rrdtool parameters are mandatory? 

RRDtool 1.4.5, got from this page https://sites.google.com/site/christiankrausse/projekte/perl/rrds-perl-windows-v

thanks for any hints, Petr Laznovsky
