asp.net - Application Insights 的应用程序 map 不显示依赖项调用

Question

我们已将 Application Insights 添加到部署到 Azure Web 应用服务的 Asp.Net 4.5.1 应用程序中。它使用 Entity Framework 和 SqlCommands 调用数据库。

Application Insights 通过 JavaScript 和后端添加。 JavaScript 跟踪正在运行，从 Fiddler 跟踪的调用和 Azure 门户中显示的报告数据都可以看出。

对 Web 服务器的请求也会显示在报告中，但应用程序映射图表不会显示从 Web 服务器到数据库的任何依赖项调用，也不会显示任何其他依赖项。

ApplicationInsights.config 是您从“创建新项目”中获得的标准配置，但删除了 InstrumentationKey 元素。检测 key 在 global.asax 中设置为

Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration.Active.InstrumentationKey = applicationInsightsKey;

另外网络配置包含

<system.web>
    <httpHandlers>
      <add path="CombineScriptsHandler.axd" verb="*" type="AjaxControlToolkit.CombineScriptsHandler, AjaxControlToolkit" />
    </httpHandlers>
    <httpModules>
      <add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" />
    </httpModules>

...

  <system.webServer>
    <modules runAllManagedModulesForAllRequests="true">
      <remove name="ApplicationInsightsWebTracking" />
      <add name="ApplicationInsightsWebTracking" type="Microsoft.ApplicationInsights.Web.ApplicationInsightsHttpModule, Microsoft.AI.Web" preCondition="managedHandler" />
    </modules>

如何从 AI 跟踪的 Web 服务器获取数据库查询数据？

更新

我将 Web 项目升级到 .Net 4.6.1，并开始看到一些依赖项，但看不到实际的 SQL 查询文本。为了解决这个问题，我通过 Azure 门户在应用服务中安装了 AI Status Monitor 扩展。之后，我完全没有看到任何依赖项调用，并且包含 ApplicationInsightsExtension.log:

那么如何通过 sql 查询文本日志记录来获取依赖项日志记录呢？

我有预感，如果我在 applicationinsights.config 文件中有遥测 key ，那么这会起作用，但我想从应用程序设置中以编程方式进行设置。

据此:https://azure.microsoft.com/en-us/documentation/articles/app-insights-dependencies/

要获取依赖项，您需要安装状态监视器或将应用程序升级到 .NET Framework 4.6 或更高版本。
