Prometheus在Spring 2.1.6到2.2.2升级时不输出Kafka消费者数据

Question

我们将Spring版本从2.1.6升级到2.2.2。在2.1.6中的Prometheus端点中看到的一些属性在2.2.2中不可见。

• kafka_consumer_records_consumed_total_records_total
• kafka_consumer_records_lag_records
• kafka_consumer_fetch_latency_max_seconds
• kafka_consumer_bytes_consumed_total_bytes_total

但是，这些数据正在MBeans中注册。

kafka_consumer_records_consumed_total_records_total示例

​

​

我是不是漏掉了一些配置？如何将MBeans中可用的数据导出到执行器端点("/prometheus")？

更新:我们在这两个版本中使用的Prometheus版本是相同的。

Answer 1

Kafka指标使用的是JMX，JMX在Spring 2.2中默认禁用。您需要为Kafka启用JMX，即在您的配置中启用spring.jmx.enabled=true。
