[rrd-users] Re: strange graphing problem

[Nicholas Lagaros]

That is what I thought initially, so I put the actual real name in there and
it did the same thing.  It is strange because it is actually reading the rrd
file because it is computing all the information it spits out in the
GPRINTS.

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.
