The overload indicators are strange to me. For example, one indicator is "IO thread idle below 20%: this means the pool of worker threads used by kafka for handling client requests are too busy to handle any more workload". How did they determine this? Is it true? I think a much better way would be to monitor the JMX reporter for dropped messages or high latency: https://docs.confluent.io/current/kafka/monitoring.html https://docs.confluent.io/current/kafka/monitoring.html.
