spring - Spring Actuator-来自Docker容器的指标聚合

Question

我有一个Spring Boot REST服务应用程序。该应用程序使用Spring Actuator来显示指标和健康信息。如何从运行同一应用程序的两个或多个容器中聚合此信息？

Answer 1

您需要将度量标准导出到中央系统。

Spring Boot provides a couple of implementations of a marker interface called Exporter which can be used to copy metric readings from the in-memory buffers to a place where they can be analyzed and displayed.

更具体地说，个人而言，我喜欢将指标导出到statsD

To export metrics to Statsd, make sure first that you have added com.timgroup:java-statsd-client as a dependency of your project (Spring Boot provides a dependency management for it). Then add a spring.metrics.export.statsd.host value to your application.properties file. Connections will be opened to port 8125 unless a spring.metrics.export.statsd.port override is provided. You can use spring.metrics.export.statsd.prefix if you want a custom prefix.

上面的信息全部来自Spring Boot文档中的指标: https://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-metrics.html
