I am learning (very slowly) that using underscores (_) in column names can be a very bad thing.
This really comes to light when I try to graph the data from one of those pages... If the data requires an NCV_* entry in xymonserver.cfg, I never get any data in the server's rrd data folder.
Is there a quick way to get around that (I am apparently really fond of using underscores in names)?

It's not something that was deliberately broken, but from a quick look at the code I don't really see why it would break.
Can you provide an example for one of these, with the data that you send for the NCV handler, and the NCV_blabla setting you're using ?
Is the RRD file created, but doesn't get any data, or does it never appear?
What's in the rrd*.log files, if anything ?
What Xymon version are you trying this with ?

Well, I'll be monkeyed.
Turns out that I was passing DS names that were too long into RRD. They were getting truncated and then causing a conflict.
Log and short...user error. Sorry about that. It DOES work if you do everything else right.
