In that point i'm absolutely flexible in the naming of the measured value.

I know what you mean. To consider, if a system has got a problem, there 
should always be more than only one measurement evaluated. It really 
means nothing, if the load exceeds the # of cpus as long as idle-time, swap
and memory aren't going out of resources. But in this case it may be another
helpful indicator of possible problems.

Doesn't matter. 2 admins, 3 opinions and 5 solutions... ;-)
