> Key: KAFKA-19117
> URL: https://issues.apache.org/jira/browse/KAFKA-19117
> Project: Kafka
> Issue Type: Improvement
> Components: clients
> Affects Versions: 3.6.2
> Reporter: Ravi Kalasapur
> Priority: Minor
>
> We experienced an outage in our application due to a built up Kafka lag,
> which we eventually discovered to be the problem with Kafka Clients being
> throttled.
> Even when using the confluent cluster, the dashboard does point to exceeding
> the quota of the principal.
> It will be nice, if the log message on the client side is a WARNING. This
> helps those who don't have visibility to cluster, and just look at the
> problem from the client side, setup alerts etc. (instead of enabling TRACE to
> figure out where the problem is)
>
> NetworkClient#maybeThrottle
> {code:java}
> log.trace("Connection to node {} is throttled for {} ms until timestamp {}",
> nodeId, throttleTimeMs, now + throttleTimeMs); {code}
