Hi Tony, Thanks for the KIP! I agree that we should keep and fix the existing metric. Adding a broker and controller-specific metric makes it more explicit for operators who monitor this metric. One thing to keep in mind when fixing the existing `RequestHandlerAvgIdlePercent` metric is that we should not couple its denominator value with the mode of kafka being run (isolated or combined). We could very well introduce another thread pool in the future.
