[rrd-users] Re: strange graphing problem

[Geert van der Ploeg]

I think there's a error in the interpolation of the $argv variables...

When just replacing the variables with real names, the shell-version of the
script creates a good graph in my environment.

So, imho, there's nothing wrong with the rrd syntax.



HTH.
