Spring开机微表datadog插座连接错误

Question

我正在为我的spring boot 2 rest api创建一些自定义指标。我已经添加了所需的微米和数据狗依赖项。我的办公室机器在代理后面工作。我必须通过spring boot插件设置代理。

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

以下是我的申请。属性文件。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

但是我得到了套接字连接超时。

就我调试io.micrometer.core.ipc.http.HttpUrlConnectionSender.send方法失败，我不知道微米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？我使用的是Spring启动 2.2.4.版本

Answer 1

如果您尝试连接到数据狗的 HTTPS 网址（在您的示例中 https://app.datadoghq.com），则需要设置 https.proxyHost 系统属性才能使其生效 - http.proxyHost 适用于 HTTP 网址[1]。这些是系统范围的设置，如果未将代理传递给其构造函数，则默认的服务器（代理）将使用这些设置。

这是指一种不同类型的代理，您将配置该代理以在内部网络上接收 Datadog 流量，并将其转发到网络外部的 Datadog。如果您使用的是 HTTP 代理，则应使用系统属性或配置了 HTTP 代理的 Http 服务器（例如，一个 HttpUrl 连接信号转换器并将代理传递给其构造函数）。

您可以使用< code >生成器配置带有< code > datadogmertregistry 的自定义< code>HttpSender。如果您将它作为< code>@Configuration类中的< code>Bean公开，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();
}
