Spring boot metrics + datadog
提问by jfcorugedo
Does anyone know how to integrate Spring boot metrics with datadog?
有谁知道如何将 Spring 启动指标与 datadog 集成？
Datadogis a cloud-scale monitoring service for IT.
Datadog是一种面向 IT 的云规模监控服务。
It allows users to easily visualice their data using a lot of charts and graphs.
它允许用户使用大量图表和图形轻松地可视化他们的数据。
I have a spring boot application that is using dropwizardmetrics to populate a lot of information about all methods I annotated with @Timed.
我有一个 Spring Boot 应用程序，它使用dropwizard指标来填充有关我用@Timed.
On the other hand I'm deploying my application in heroku so I can't install a Datadog agent.
另一方面，我在 heroku 中部署我的应用程序，所以我无法安装 Datadog 代理。
I want to know if there is a way to automatically integrate spring boot metric system reporting with datadog.
我想知道是否有一种方法可以将spring boot metric system报告与datadog自动集成。

I've finally found a dropwizzard module that integrates this library with datadog: metrics-datadog
我终于找到了一个将这个库与 datadog 集成的 dropwizzard 模块：metrics-datadog
I've created a Spring configuration class that creates and initializes this Reporter using properties of my YAML.
我创建了一个 Spring 配置类，它使用我的 YAML 的属性创建和初始化这个 Reporter。
Just insert this dependency in your pom:
只需在你的 pom 中插入这个依赖项：
<!-- Send metrics to Datadog -->
<dependency>
<groupId>org.coursera</groupId>
<artifactId>dropwizard-metrics-datadog</artifactId>
<version>1.1.3</version>
</dependency>
Add this configuration to your YAML:
将此配置添加到您的 YAML：
yourapp:
metrics:
apiKey: <your API key>
host: <your host>
period: 10
enabled: true
and add this configuration class to your project:
并将此配置类添加到您的项目中：
/**

It seems that Spring Boot 2.x added several monitoring system into its metrics. DataDog is one of them supported by micrometer.io. See reference documentation: https://docs.spring.io/spring-boot/docs/current/reference/html/production-ready-metrics.html#production-ready-metrics-export-newrelic
Spring Boot 2.x 似乎在其指标中添加了几个监控系统。DataDog 是micrometer.io支持的其中之一。请参阅参考文档：https: //docs.spring.io/spring-boot/docs/current/reference/html/production-ready-metrics.html#production-ready-metrics-export-newrelic
For Spring Boot 1.x, you can use back-ported package:
对于 Spring Boot 1.x，您可以使用向后移植的包：
compile 'io.micrometer:micrometer-spring-legacy:latest.release'
compile 'io.micrometer:micrometer-spring-legacy:latest.release'

If JMX is an option for you, you may use the JMX dropwizrd reportercombined with java datalog integration
如果 JMX 是您的选择，您可以使用JMX dropwizrd 报告器与Java 数据记录集成相结合
