Question

我正在尝试按照此处的示例向Azure Web角色添加诊断信息： https://www.windowsazure.com/en-us/develop/net/common-tasks/diagnostics/

当我在tracing下添加system.webserver元素时，我在运行网站时看到错误。甚至在OnStart中的断点被击中之前就可以看到错误。

有什么想法吗？

这是我的web.config文件，其中有问题的部分已注释掉：

以下是我解决问题的方法：

突然服务器开始打印关于500错误的详细信息（我不知道为什么，我认为我没有改变任何东西），然后我发现实际的错误是：

HTTP错误500.19：

无法使用唯一键添加“add”类型的重复集合条目   属性'path'设置为'*'

解决方法是在add标记之前添加以下行：

<remove path="*"/>

现在，tracing标记如下所示：

<tracing>
      <traceFailedRequests>
        <remove path="*"/>
        <add path="*">
          <traceAreas>
            <add provider="ASP" verbosity="Verbose" />
            <add provider="ASPNET" areas="Infrastructure,Module,Page,AppServices" verbosity="Verbose" />
            <add provider="ISAPI Extension" verbosity="Verbose" />
            <add provider="WWW Server"
            areas="Authentication,
                Security,
                Filter,
                StaticFile,
                CGI,
                Compression,
                Cache,
                RequestNotifications,
                Module"
            verbosity="Verbose" />
          </traceAreas>
          <failureDefinitions statusCodes="400-599" />
        </add>
      </traceFailedRequests>
    </tracing>

这似乎工作正常。
