You might have a problem because the original RRD was not created with the extra DS. You may have to export the existing RRD (dump), create the RRD and import the historical data. Perl is your friend.

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
