[Xymon] Need some assistance with graphs, please.

[Vernon Everett]

I think you have got me here.
The only thing I can see that's "odd" about your graph definition, is the
lack of %s at the end of each gprint line, which isn't essential, and only
impacts scaling, and the \n at the end of the last line.
The /n will impact the appearance of the text at the bottom of your graph,
but shouldn't mess up your lines.
Even without the gprint statements, you still should get a graph.

>From here, I am at a bit of a loss.

How are the rrd files being generated?
If it was me, I would double check every rrd file to make sure we have the
correct internal field name (my first thought) and then check that each one
has valid data.
I have seen situations where the rrd file ended up with 2 fields due to
badly formatted data coming from the client. I had the correct field and a
gibberish field name. The real data was going into the gibberish field, and
the correct field was going unpopulated.
Also check you debug logs to see if there is a problem with the
display/rendering of the graphs.

Regards
Vernon
