Hello Folks, I was looking through the kafka.producer metrics on the JMX interface, to find a good indicator when to "trip" the circuit. So far it seems like the "bufferpool-wait-ratio" metric is a useful decision mechanism when to cut off the production to kafka.
As far as i experienced, when kafka server slow for some reason, requests start piling up on the producer queue and if you are not willing to drop any messages on the producer, send method starts blocking because of the slow responsiveness. So this buffer pool wait ratio starts going up from 0.x up to 1.0. And i am thinking about tripping the circuit breaker using this metric, ex: if wait-ratio > 0.90 etc... What do you think? Do you think there would be a better indicator to check the health overall? Best Mete
