What other Xymon configuration have you changed (e.g. GRAPHS? I assume you 
have updated TEST2RRD or you wouldn't be getting the RRD files).

So, there is no problem with devmon, or the devmon collector (if you get RRD 
files, as all they do ends here).

The devmon collector generates one rrd file per line of content between the 
DEVMON RRD header and the end-of-html-comment.

No, this should result in having one graph for each RRD file, with '21.5' 
being a value provided for the graph legend.

As Jeremy found, hacking the linecount= in the message can affect how many 
values Xymon's htmlgen.c decides to show on a specific graph.

The TABLE portion should not be necessary, but I haven't personally tried 
this.

I think we need a cleaner solution (which I will try and work on this week, as 
I need it) to badly designed SNMP tables.

You would need to delete the rrd file when you change the number of DSs (or, 
export, modify the xml to add a new one, import, if you want to keep the 
data).
