OK, I'll ask
We're interested in tracking CPU load because we'd like to apply any otherwise unoccupied CPU horsepower to sampling and smoothing noisy sensor inputs. It's easy enough to write a Thread (we're using Java) to do this as fast as it can, but we don't want to risk starving more important tasks.
It's a lot easier to tune things like this if there's an easy way to watch CPU loads during development. Any hints?
