Graph definitions

[Everett, Vernon]

Hi all

Is there any way to define a graph definition for values that may or may not be available.

Let's work with CPU temperature, just as an example.

In hobbitserver.cfg, I can define this
NCV_systemp="*:GAUGE"
(And the other ncv definitions)
It then generates rrd files for all the servers.

However, some systems have 1 cpu, some have 2, and some 4.
So the rrd files only have entries for the number of CPUs.

In the hobbitgraph.cfg we can define the graph, with 4 cpu temperatures, but if the rrd file doesn't contain 4 fields (i.e. system has only 2 CPUs), it doesn't generate a graph.
It is also not possible to have a separate graph definition for 1, 2 and 4 CPU systems.

The other way round it, is to have each CPU in a separate file, and define FNPATTERN= with a wildcard.
But how do we get the ncv module to put each field in a sepreate rrd file?

Regards
