[Xymon] Load Average threshold - a mathematic rule regarding the number of threads ?

[Steve Holmes]

We would love to be able to do something like that. Currently we do, like
you, per host or per page ad hoc LOAD specs. Typically we watch a system
for a few weeks to find the 'normal' load and adjust the config
accordingly. If we could have a default that is calculated based on number
of cpus/thread, it would go a long way to not needing per host specs.
