I use to get the same thing on my NT/2000 versions of Perl scripts. The
combination I found that works is this:
- Make sure that your output file (GIF/PNG) is formatted like this:
c:\\inetpub\\graphs\\output.gif
- Make sure that your RRD definitions are like this:
c\\:\\inetpub\\wwwroot\\mrtg\\rrdtool\\drmateo_e4.rrd:ds0:AVERAGE
The reasons for this are:
- Windows uses \ as directory layer separators, but Perl uses that as an
escape code for special characters, that is why when you want to send a \ to
the RRD Perl module you need to feed it a \\. Otherwise Perl thinks it's an
escape character meant for the Perl interpreter.
- The \\ is required before the : of the "c\\:\\inet..." because RRDTool is
looking for : as a field separator, so you need to tell the RRD Perl module
to treat it like a special character. So we need to feed it a \: but as
stated above when we need to feed the RRD Perl module a \ we need to send a
\\ to get past Perl thinking it's an escape character for it.
- We don't need a \\: in the output file definition because RRDTool isn't
using : as a field separator and will treat it literally.
I hope this helps, and doesn't just confuse the problem further. :-)
Feel free to email me if you would like me to try and come up with a better
explanation.

Hi
I've tried your suggestion C\\:\\... and some combinations of it but still
couldn't get it done. Either I get the same "can't parse DEF.." error or the
rrdtool said it can't find the specified file, dependig on the combination
of \\, \, //, etc I use.
Regards
Alvaro

Try this:
C\\:\\Inetpub\\wwwroot\\mrtg\\rrdtool\\.........
