I suspect it just got missed in the stack of emails. Hopefully it will percolate to the top soon. Bill Richardson wrote:
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 :
--- do_ncv.c.old 2007-09-11 15:00:20.000000000 +0200 +++ do_ncv.c 2007-11-26 16:36:43.000000000 +0100 @@ -177,7 +177,7 @@ } }
- if (split_ncv && (paridx > 1)) { + if (split_ncv && (paridx > 0)) { 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 !
