Okay, this is okay for some machines. We've got this automated build
server here, though, which is busy for an hour or two

Ah, thatswhy I had idle_red=0.00 on some machines - this seemed to work
as well. I'm trying idle_red=-1 now.

Thanks, I'll try that as well. :-)

I'd like a graph for load as well... Shouldn't be too difficult, right?

It's a bit irritating to have load and cpuload... So, the load test
reports idle/sys/waiting/user time and provides performance data while
the cpuload test just looks at the load average, right?

Thanks,

Tino.
