split-ncv not working in Xymon 4.3.0-0.beta2

[Bill Richardson]

I tried to use the split-ncv function in Xymon 4.3.0 beta2 and get the following error in the rrd-status.log:
 
2009-07-14 13:49:46 RRD error creating /home/xymon/data/rrd/hostname/column,test.rrd: Duplicate DS name: lambda
 
I did a search on the mailing list and found Charles posting with a patch for this dated back in Nov 2007. I made the change and recompiled and it fixed the problem.
 
The change to be made is still at line 177 of the do_ncv.c
 
Change from  "if (split_ncv && (paridx > 1)) {"
Change to  "if (split_ncv && (paridx > 0)) {"

 
 Does anyone know why the following changes didn't make it to the current versions of Xymon?
 
Thanks

Hi Henrik,

I tried to update my hobbitd_rrd to the current snapshot version, and I
got loads of "Duplicate DS name: lambda" when using split-ncv.

I found the error lies here :

                                create_and_update_rrd(hostname,
testname, params, NULL);
 
                                /* We've created one RRD, so reset the
                                 * params for the next one */

With this modification, it works.

Thanks for your great software ! I hope 4.3 will be out soon !
