Hi, As part of KAFKA-1928, we need to consolidate existing SocketServer metrics into Selector metrics.
The two metrics are: 1. NetworkProcessorAvgIdlePercent 2. ResponsesBeingSent NetworkProcessorAvgIdlePercent is currently implemented as Meter, which seems to translate nicely into KafkaMetrics Rate. ResponsesBeingSent is a gauge, which doesn't have a direct KafkaMetrics equivalent, but should be easy to add. However, I'm considering dropping ResponsesBeingSent gauge completely - I find it useless. Selector currently has Rates for requests-sent, responses-sent, bytes-sent, bytes-received. Anyone finds ResponsesBeingSent useful and wants to make a passionate plea to keep it around? (I CCed the people I think will care, in case they are not watching the list) Gwen
