[Xymon] Multiple graphs on one web page - not being shown

[John Horne]

Hi,

Using the Terabithia RPMs I have created a custom test called 'es' (it's for
some stats from an elasticsearch search engine). I created a client-side script
to gather the current status and data for the graphs.

The 'status' message gets sent okay, and an 'es' column is created and the web
page shows a one-line summary of the search engine - e.g. 'It's fine', 'It's
not fine' etc. It changes colour depending on the colour being sent by the
client-side script. This works too.

The 'data' message from the script is also sent okay, and has created 3 RRD
files for the host. These are named 'es_heap.rrd', 'es_rates.rrd' and
'es_latency.rrd'. The values within them are being updated, and if I use a
crafted URL (using showgraph.sh) I can see that graphs for them are valid.

However, what I wanted was all 3 graphs to appear on the 'es' status page.
I have added 'es' as a test name to the hosts in the 'hosts.cfg' file. I have
also added 'es' to the TEST2RRD definition, but I'm not sure that is needed in
this case. I have also added 'GRAPHS_es="es-rates,es-latency,es-heap"' to the
'xymonserver.cfg' file. Within the 'graphs.cfg' file I have created the 3 graph
definitions using the 'GRAPHS_es' names.

For some reason though the graphs do not appear. We have several custom tests
which produce a single graph, but this is the first where we want more than one
graph shown.

Anyone any ideas about this?

As said, the RRD files are created and updated, using a browser I can see the
graphs so the definitions are fine. The 'es' status page shows no broken graph
link, it just shows the text I expect and then the usual 'Status unchanged'
message. Just no graphs.



Thanks,

John.
