[Xymon] Custom Graphs

[Chris.Morris at rwe.com]

The comments in the "xymonserver.cfg" file are quite clear :-

TEST2RRD 
# This is also used by the svcstatus.cgi script to determine if the
detailed
# status view of a test should include a graph.

GRAPH
# This defines which RRD files to include on the "trends" column
webpage,
# and the order in which they appear.

The answer to this question I found is "no, the feature was indeed
available in 4.2.3 but just missing from that section of the docs."

And this was correct as well.

A followup question relates to the apparent requirement that you add the
RRD/test name to both the GRAPH and the TEST2RRD variables in the
hobbitserver.cfg. Is there any way to add the graph to just the test
page and not the trends page? Why do both of these variables exist if it
seems like you need both of them for it to work?
