spring-boot - Spring boot千分尺datadog套接字连接错误

问题描述

我正在为我的 spring boot 2 rest api 创建一些自定义指标。我添加了所需的千分尺和数据狗依赖项。我的办公机器在代理后面工作。我通过 spring boot 插件设置了代理。

-Dhttp.proxyHost=xxxx.proxy.com
-Dhttp.proxyPort=xxxx

下面在我的 application.properties 文件中。management.metrics.export.datadog.apiKey=mykey

management.metrics.export.datadog.uri=https://app.datadoghq.com

management.metrics.export.datadog.enabled=true

management.metrics.export.datadog.step=10s

但我得到了套接字连接超时。

据我调试 io.micrometer.core.ipc.http.HttpUrlConnectionSender.send 方法失​​败，我不知道千分尺数据狗如何获取代理详细信息。

千分尺医生说

management.metrics.export.datadog.uri=https://app.datadoghq.com # URI to ship metrics to. If you need to publish metrics to an internal proxy en-route to Datadog, you can define the location of the proxy with this.

但我不明白这是什么意思？我应该用我的代理 url 替换这个 url 还是代理有任何特定的 uri 模式？我正在使用弹簧启动 2.2.4.RELEASE

解决方案

如果您尝试连接到 Datadog 的 HTTPS URL（https://app.datadoghq.com在您的示例中），那么您需要设置https.proxyHost系统属性以使其生效 -http.proxyHost适用于 HTTP URLs[1]。这些是系统范围的设置，如果 a未传递给其构造函数，则默认HttpSender( )将使用这些设置。HttpUrlConnectionSenderProxy

这是指您将配置为在内部网络上接收 Datadog 流量的不同类型的代理，并将其转发到网络外部的 Datadog。如果您使用的是 HTTP 代理，那么您应该使用系统属性或HttpSender配置您的 HTTP 代理的 an（例如 anHttpUrlConnectionSender并将 a 传递Proxy给它的构造函数）。

您可以使用其配置HttpSender自DatadogMeterRegistry定义Builder。如果你Bean在一个@Configuration类中公开它，Spring Boot 将在其自动配置中使用它。例如：

@Bean
public DatadogMeterRegistry datadogMeterRegistry(DatadogConfig config, Clock clock) {
    HttpSender httpSender = new HttpUrlConnectionSender(config.connectTimeout(), config.readTimeout(), new Proxy(Proxy.Type.HTTP, new InetSocketAddress("myproxy", 8080)));
    return DatadogMeterRegistry.builder(config).clock(clock).httpClient(httpSender).build();
}
