Re: Review Request 19388: Patch for KAFKA-1251

5. Got it. It wasn't obvious to me that KafkaMetrics.lock is actually the sensor lock. Perhaps we could rename it to sensorLock?

7. Yes, that's another issue. My original question is a bit different. Say we keep one sample with a window size of 30 secs. At time 20 sec an event is recorded. We will use 1/(now - 20) to calculate the rate. However, there wasn't any update from 0 to 20. So, may be the rate should be 1/(now - 0)?

I think at least for request rate, it's probably useful to see the producer request and metadata request separately at the client?
