[Xymon] about trends and multigraph

hello

I'm reading the code and I love this :). That should be an interesting way.

                    /* 
                     * Some reports (disk) use the number of lines as a rough measure for how many
                     * graphs to build.
                     * What we *really* should do was to scan the RRD directory and count how many
                     * RRD database files are present matching this service - but that is way too
                     * much overhead for something that might be called on every status logged.
                     */

btw :

I forced this <!-- linecount=6 --> into the status. ( I send the data with the data channel not in the status channel)

system qq/ $ENV{'BB'} $ENV{'BBDISP'} "status $ENV{'MACHINE'}.jvm $color $line $date"/; system qq/ $ENV{'BB'} $ENV{'BBDISP'} "data $ENV{'MACHINE'}.trends\n$trends"/;

but it's not working as I want.

I need the following value to make it :

&service=jvm&graph_width=576&graph_height=120&first=1&count=1& &service=jvm&graph_width=576&graph_height=120&first=2&count=1& &service=jvm&graph_width=576&graph_height=120&first=3&count=1& &service=jvm&graph_width=576&graph_height=120&first=4&count=1& &service=jvm&graph_width=576&graph_height=120&first=5&count=1& &service=jvm&graph_width=576&graph_height=120&first=6&count=1&

but as I can understand in the source code I completely wrong :(

and I got :

&service=jvm&graph_width=576&graph_height=120&first=1&count=3& &service=jvm&graph_width=576&graph_height=120&first=4&count=3&

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

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 :)
