从 Spring Boot 2.1.6 升级到 2.2.2 时，Prometheus 不导出 Kafka Consumer 数据

Posted 2023-02-15

【中文标题】从 Spring Boot 2.1.6 升级到 2.2.2 时，Prometheus 不导出 Kafka Consumer 数据

【英文标题】：Prometheus not exporting Kafka Consumer data upon upgrade from Spring Boot 2.1.6 to 2.2.2

【发布时间】：2020-04-17 23:02:26

【问题描述】：

我们将 Spring Boot 版本从 2.1.6 升级到 2.2.2。在 2.1.6 的 Prometheus 端点中看到的某些属性在 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，此数据正在 MBean 中注册。

kafka_consumer_records_consumed_total_records_total 示例

我是否缺少一些配置？如何将 MBean 中可用的这些数据导出到执行器端点（“/prometheus”）？

更新：我们在两个版本中使用的 Prometheus 版本是相同的。

【问题讨论】：

你能报告一下传递版本的变化吗？例如之前和现在的 Micrometer 和 Kafka 客户端的版本是什么？

@checketts 升级前后的版本是一样的。 1.3.2.我已经用信息更新了问题。

我为此提出了一个错误。 github.com/spring-projects/spring-boot/issues/19507

【参考方案1】：

Kafka 指标使用 JMX，从 Spring Boot 2.2 开始默认禁用 JMX。您需要启用 JMX 才能使 Kafka Metrics 正常工作，即配置中的 spring.jmx.enabled=true。
