JMX not fetching a few Kafka metrics
I'm currently digging this issue, but wanted to let the maintainers about it. Essentially I'm running Kafka and for some metrics I'm getting nothing, with errors showing up in the logs, such as:
- WARNING: No valid value(s) for kafka.producer.record-send-rate
- WARNING: Failed to fetch MBean kafka.producer:client-id=*,type=producer-metrics.
- WARNING: No valid value(s) for kafka.logs.flush.time.count
This is using Kafka 3.1.0 with Java 15.
