after migration to xymon 4.3.3 Beta 2 from 4.2.0, our rrd files, built with SPLITNCV where not working anymore

splitncv separates rrd values to own files, making it easy to generate graphs for an unknown number of output values using regexp
for network interface performance monitoring for example, where the number of interfaces may differ from host to host

 

no updates on existing rrds, and no new ones where created

we spent a lot of time in searching for configuration problems, maybe leading to this problem

but then we found this in xymon mailing list:

http://www.hswn.dk/hobbiton/2009/07/msg00242.html

 
in short:

go to xymon-4.3.0-beta2 directory

change to hobbitd/rrd

and edit the source file do_ncv.c

change line 180:

if (split_ncv && (paridx > 1)) {

 
to

if (split_ncv && (paridx > 0)) {

 
recompile, exchange the new compiled hobbitd_rrd with the one in

server/bin

restart hobbit

should be working now
