Point taken on the configurability.
I think a strong argument can be made for the number of cores as being the
default for cpu_num.
However, it's also quite sensible to have the other two measures: number
of physical CPUs,
and number of virtual CPUs (what gmond currently reports).
How about, instead of cpu_num, reporting:
cpu_count_cores
cpu_count_physical
cpu_count_virtual
They are all very easily calculated based on the contents of /proc/cpuinfo
under Linux. I am not
as certain how one would go about calculating all three in other
environments...
Given that one had all 3, one could make the load calculation configurable
thus:
metric {
name = "load_one"
value_threshold = "1.0"
basis = "cpu_count_cores"
}
Comments?
