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的示例

在此处输入图像描述

我错过了一些配置吗？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。

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 工作，即spring.jmx.enabled=true在您的配置中。
