OK, I got further with this. As it turns out, this IS hard coded in the
source code. First place is xymon-4.2.3/hobbitd/do_rrd.c as extracted
from the source:

- ---
# diff do_rrd.c.orig do_rrd.c
389c389
<       else if (strcmp(id, "temperature") == 0) res =
do_temperature_rrd(hostname, testname, msg, tstamp);
- ---
>       else if (strcmp(id, "temp") == 0) res =
do_temperature_rrd(hostname, testname, msg, tstamp);
- ---

...but there's also an included file, ./rrd/do_temperature.c:

- ---
# diff do_temperature.c.orig do_temperature.c
16c16
<
"DS:temperature:GAUGE:600:1:U",
- ---
>                                             "DS:temp:GAUGE:600:1:U",
84c84
<                       savech = *(p+1); *(p+1) = '\0';
setupfn("temperature.%s.rrd", bol); *(p+1) = savech;
- ---
>                       savech = *(p+1); *(p+1) = '\0';
setupfn("temp.%s.rrd", bol); *(p+1) = savech;
- ---

...I don't have graphs yet, but I think it might be the averages taking
awhile. I guess we'll see. I do have RRD files now; anyone have any idea
what to do if there are ultimately no graphs even with RRD files?
