Description

KIP-402 (in https://issues.apache.org/jira/browse/KAFKA-7719) added new metrics of

 

kafka.network:type=SocketServer,name=ControlPlaneNetworkProcessorAvgIdlePercent

kafka.network:type=SocketServer,name=ControlPlaneExpiredConnectionsKilledCount

 

There is no documentation on these metrics on http://kafka.apache.org/documentation/. We should update the documentation to describe these new metrics.

 

I'm not 100% familiar with them, but it appears they are measuring the same thing as 

kafka.network:type=SocketServer,name=NetworkProcessorAvgIdlePercent

kafka.network:type=SocketServer,name=ExpiredConnectionsKilledCount

 

except for the control plane, instead of the data plane.
