【中文标题】Application Insights javascript sdk 无法正常工作【英文标题】：Application Insights javascript sdk not working 【发布时间】：2022-01-04 06:48:06 【问题描述】：我有一个 mvc5 应用程序，我想在应用程序洞察中启用服务器端和客户端日志记录。服务器端日志记录按预期工作正常，但问题出在客户端日志记录中。在布局页面中，我在此处提到的“head”标签中添加了以下脚本 (https://docs.microsoft.com/en-us/azure/azure-monitor/app/javascript)
<script type="text/javascript">

</script>
但问题是它不起作用。如果我在应用洞察中转到性能选项卡并转到浏览器选项卡，它是空的。我不确定我在这里做错了什么。
这是我的应用洞察配置文件

更新：
我也尝试添加更多配置选项，如下所示，但仍然没有成功。
cfg: // Application Insights Configuration
instrumentationKey: "InstrumentationKey",
enableDebug: true,
verboseLogging: true,
disableFetchTracking: false,
enableCorsCorrelation: true,
enableRequestHeaderTracking: true,
enableResponseHeaderTracking: true
此外，在“网络”选项卡中，我可以看到对“https://dc.services.visualstudio.com/v2/track”的跟踪调用，响应如下：
"itemsReceived":2,"itemsAccepted":0,"errors":["index":0,"statusCode":206,"message":"Telemetry sampled out.","index":1,"statusCode":206,"message":"Telemetry sampled out."],"appId":"my-app-id"
【问题讨论】：
【参考方案1】：我正在关注doc 在asp.net mvc 应用程序中实施应用程序洞察力。
您已经在 Views\Shared\_Layout.cshtml 和 appinsights.config
如果不是，请按照以下步骤操作：
打开 Views\Shared_Layout.cshtml
此文件是此应用程序呈现的 HTML 页面的最外层模板。 Application Insights 已在 head 标记内插入初始化代码，以便您可以立即开始使用 JavaScript API 来检测应用程序的客户端部分。在instrumentationKey中添加您的Application Insights密钥：“Your key here”这部分。

< /script>
打开 ApplicationInsights.config 文件并检查您的 application insights 标记/connectionString 标记，其中包含应用程序洞察检测密钥。
如果不是，您需要通过右键单击项目来配置 Azure application insights，并在本地/Azure 配置您的应用程序洞察力。
默认情况下，它会在 ApplicationInsights.config 文件中添加您的应用程序洞察 连接字符串 标记
< ConnectionString> Your app insights connection string < /ConnectionString>
如果没有，您可以添加 Instrumentation 键标签
< InstrumentationKey> Your instrumentation key < /InstrumentationKey>
运行您的应用程序并在 application Insights 中查看结果
性能标签
如果您在本地添加了应用程序洞察力，请在 VS 中的应用程序洞察力按钮中查看结果
