Perhaps the underscore is also considered a valid character. I can process dataset names with underscores using the extra tests and script. Also, I changed do_ncv.c to allow underscores in the dataset name.
if ( ((*inp >= 'A') && (*inp <= 'Z')) ||
((*inp >= 'a') && (*inp <= 'z')) ||
((*inp >= '0') && (*inp <= '9')) ||
((*inp == '_') ) ) {Here's a dump from my rrd file:
hobbit at hobbit:~/data/rrd/vm1> rrdtool fetch pg_util.rrd AVERAGE -r 900 -s -60m pg_util
1131975600: 1.0000000000e+00 1131975900: 1.0000000000e+00 1131976200: 1.0000000000e+00
Now that my rrd file is being updated, I have to figure out why the graph isn't appearing.

OK, I think I've found the problem. The NCV routine strips out anything that isn't a letter or a number from the column name.
I found this message in the log:
2005-11-13 22:01:21 RRD error updating /home/hobbit/data/rrd/vm1/pg_util.rrd from 192.168.201.1: unknown DS name 'pgutil'
That is because the RRD library only allows data-set names to contain letters and numbers.
