> Issue Type: Task
> Components: consumer, log
> Affects Versions: 3.7.0
> Reporter: Philip Nee
> Assignee: Apoorv Mittal
> Priority: Major
> Labels: consumer, logging
>
> While running system tests locally, I've noticed excessive logging of the
> Telemtry Reporter. This I believe was introduced in KIP-714.
> {code:java}
> [2024-01-15 09:44:16,911] DEBUG For telemetry state SUBSCRIPTION_NEEDED,
> returning the value 224678 ms; the client will wait before submitting the
> next GetTelemetrySubscriptions network API request
> (org.apache.kafka.common.telemetry.internals.ClientTelemetryReporter) {code}
> This is logged several times per ms - Also, given the amount of log being
> emitted, can we also check the CPU profile to see if there's a process
> running a tight loop?
>
> Update
> -----------
> Looking from the beginning, is this caused by the following?
> {code:java}
> DEBUG The broker generated an error for the get telemetry network API request
> (org.apache.kafka.common.telemetry.internals.ClientTelemetryReporter)
> 146 org.apache.kafka.common.errors.UnsupportedVersionException: The node
> does not support GET_TELEMETRY_SUBSCRIPTIONS {code}
