[Xymon] Temperature graphs

I've got a couple snmp tests and I'm trying to graph their output.  I 
tried putting in my own rrd script to collect the data, but there seems to 
be a built-in one overriding mine.  So, I tried to format my test output 
to work with that, but I'm just getting rrd files that lack any data.

The main line of the test is like this:
   &green Routing Engine Temperature 43

It causes the creation of a file like this:
   /var/lib/hobbit/rrd/<hostname>/temperature.Routing_Engine_Temperature.rrd

When I use "rrdtool dump" I still get data like this and an empty graph.
   <!-- 2015-06-11 11:20:00 PDT / 1434046800 --> <row><v>NaN</v></row>
   <!-- 2015-06-11 11:25:00 PDT / 1434047100 --> <row><v>NaN</v></row>

If someone knows the correct format for temperature tests, I'd be set.


Also, we've got snmp collecting memory data for some equipment that we'd 
like to override internal graphing on specific hosts if that can be done. 
Reformatting output on that may be a bit harder.

The obvious answer is to change the test names for our custom ones, but my 
boss is very opposed to creating new columns in xymon.

Thanks,
