Re: [xymon] rrd change

[Vernon Everett <everett.vernon (at) gmail.com>]

Then the answer is simple.
This applies to the memory test, which is a Xymon default or built-in test.
So it gets special treatment.
Change the name of your test, call it mem, or memory2 or anything else not
already used, and treat it as a custom test.
You need to add it the GRAPHS= TEST2RRD= and add an NCV_Testname in the
hobbitserver.cfg and it should work.
Just remember to create a corresponding entry in the hobbitgraph.cfg script,
and changes to hobbitserver.cfg need a restart of the server.
It should just work.

Cheers
