"unknown DS name" question.

I have an xymon script that was producing the following web information. From this information I was plotting "Delta Pages Printed". Data and graph was working great until..... Here is the old web data.

Printer Counter = 1869893
Total Pages Printed Since 2010/02/17/18/18/32 = 2810
Delta Pages Printed = 0

I needed to enter another line in the web data and now it looks like:

Printer Counter = 1869893
Printer Cartridge Counter = 10803
Total Pages Printed Since 2010/02/17/18/18/32 = 2810
Delta Pages Printed = 0

I added the "Printer Cartridge Counter =" but I still only wanting to graph the "Delta Pages Printed".

Rrd-status.log is now giving the following messages:

2010-02-22 15:48:25 RRD error updating /local/xymon/data/rrd/lp.math.purdue.edu/Prn.rrd from 128.210.33.225: unknown DS name 'PrinterCartridgeCou'

And if I go to the data/rrd/lp.math.purdue.edu and run "rrdtool dump Prn.rrd" it in fact does not have a ds 'PrinterCartridgeCou'

My question is how do I update the current Prn.rrd?

Thanks

Robert
