[Xymon] Multiple graphs for one test

Wed Apr 26 16:59:49 CEST 2017

The multigraphs option tells xymon to graph up to 4 variables on a graph then move to the next graph, on and on, for the test names passed to the multigraphs option.

If that fixes the problem, I'd be curious to understand why.  That is not in my configs and I'm running 4.3.28 (terabithia).  I'm fairly certain it worked on 4.3.17 (non-terabithia) but I won't swear to it in court.

I believe what you're looking for is in cgioptions.cfg.  Here's the relevant line from mine:

# svcstatus.cgi options for a normal (current) status display
CGI_SVC_OPTS="--env=$XYMONENV --no-svcid --history=top --multigraphs=jboss,JMSQueue,cpustat"

Thanks for the information. I think I followed what you said, but I seem to be missing something along the way.

I have this as part of the TEST2RRD definition in the xymonserver.cfg file:

jboss=ncv

I also have this in the xymonserver.cfg file:

SPLITNCV_jboss="*:GAUGE"
GRAPHS_jboss="jboss,jboss1"

Xymon is creating the jboss,*.rrd files as expected.

In the graphs.cfg file, I have two graphs defined as shown below. The first one graphs two data points and the second one graphs three.

Xymon only displays the graph named "jboss". If I flip the names of the two graph definitions ([jboss] becomes [jboss1] and [jboss1] becomes [jboss]), Xymon still only shows one graph, but now it shows the one with three data points instead of two. (Whichever one defined as [jboss] is the one displayed.)

If I view the graph in my browser, I'm able to manually change the "service=ncv:jboss" in the URL to "service=ncv:jboss1" and see the other graph.

So the data collection is working, the graph definitions are OK, and the graphs are being generated. The only thing left is to get both graphs to display on the same page at the same time.

In case it matters, this is Xymon 4.3.17 running on Fedora 20.
