I think I may have identified a possible bug in xymon. I am
currently running 4.3.12.<br>
<br>
</div>
I am attempting to define a custom graph using the RRDPARAM
variable to define the graph. The data that is "supplying" the
graph is being generated by a custom check and it stores this
data over several rrd files with a single value in each file.<br>
<br>
</div>
<div>They key line in my graph definition is:<br>
<br>
</div>
<div>DEF:p@RRDIDX@=@RRDFN@:@RRDPARAM@:AVERAGE<br>
<br>
</div>
<div>What appears to be happening is that the different
variables names that represent the different parameters for
the graph are different lengths. It seems that what ends up
being supplied to rdd on this line in the graph definition
contains extra white space added into the @RRDPARAM@ part of
the definition line and that these extra whitespaces
correspond to the largest variable name length. It seems to me
that the internal data structure is getting sized to the
largest string length and then not reduced for subsequent
smaller strings and it just pads the rest with whitespace. RRD
then gets confused as it is looking for a variable named
"variable1 ", while the rrd file actually contains a variable
called "variable1".<br>
<br>
</div>
<div>I would love to get the bug fixed as it is preventing some
of my graphs working. Happy to also be told there is a better
way to do this. I hope this makes sense. Happy to provide more
info if required.<br>
<br>
</div>

This is not a bug, it is a feature. When making multi-graphs, and
when using @RRDPARAM@ in de GPRINT-statement, the columns will
neatly line up.<br>
<br>
The graph definition shows that you have a set RRD's, each
containing a single DS with the same name as the file. Is it
possible to give the DS a fixed name, for instance 'lambda'? If so,
you can remove @RRDPARAM@ form the DEF-line.<br>
