[Xymon] Trouble starting ext test to rrd, graph

[Josh Luthman]

Thanks a ton for the help!  It looks like between xymon config and RRD
they're simply truncated and stripped of non alphanumeric characters.
(example:  totalnumqueries_ip_ratelimited) This is in the RRD (:

# rrdtool info unboundstats.rrd
<snip>
ds[totalnumqueries].last_ds = "109"
ds[totalnumqueries].value = 8.4000000000e+00
ds[totalnumqueries].unknown_sec = 0
ds[*totalnumqueriesipra*].index = 1
ds[totalnumqueriesipra].type = "DERIVE"
ds[totalnumqueriesipra].minimal_heartbeat = 600
<snip>

My RRD are actually in /var/lib/xymon/rrd *NOT* /var/lib/xymon/data/rrd so
they were actually being made. I was looking in the wrong place (guide
doesn't match my RPM).

Per the suggestion, I decided to split them using SPLITNCV.  Honestly I
don't see why you wouldn't just do this from the get go, it's so much
easier and better.
