[Xymon] about trends and multigraph

[Olivier AUDRY]

hello

I have one rrd by jvm to trend memory usage off the jvm 

-rw-rw-r-- 1 xymon xymon 209480 11 sept. 22:35 jvm.tomcat5-1.rrd
-rw-rw-r-- 1 xymon xymon 209480 11 sept. 22:35 jvm.tomcat5-2.rrd
-rw-rw-r-- 1 xymon xymon 209480 11 sept. 22:35 jvm.tomcat5-3.rrd
-rw-rw-r-- 1 xymon xymon 209480 11 sept. 22:35 jvm.tomcat5-4.rrd
-rw-rw-r-- 1 xymon xymon 209480 11 sept. 22:35 jvm.tomcat6-1.rrd
-rw-rw-r-- 1 xymon xymon 209480 11 sept. 22:35 jvm.tomcat6-2.rrd

the graphs def :

I got the trends in the jvm column and in the trends column but the I have all the information in the same graph => unreadable.
So I had the jvm value to the CGI_SVC_OPTS.

CGI_SVC_OPTS="--env=$XYMONENV --no-svcid --history=top --multigraphs=jvm,disk,inode,qtree,if_load,if_err,if_col,vip-bandwith,diskstats"

On the column jvm I got the graph for the first rrd but not for the others. If I tweak the url with the right value for first and count
I can find the graph for the other rrd.

I suspect the value in the html <!-- linecount=1 --> should not be at 1 but I don't understand how this is set.

Any help would be much appreciated :)
