[英]MVC 4 Azure web role: Error 500 when adding the “tracing” element to web.config
我正在尝试通过以下示例将诊断添加到Azure Web角色: https : //www.windowsazure.com/en-us/develop/net/common-tasks/diagnostics/
在system.webserver
下添加tracing
元素时,运行网站时看到错误。 即使在命中OnStart
的断点之前也可以看到该错误。
有任何想法吗?
这是我的web.config
文件,其中有问题的部分已被注释掉:

这是我解决问题的方法:
突然服务器开始打印有关500错误的详细信息(我不知道为什么,我认为我没有更改任何内容),然后我发现实际的错误是:
HTTP错误500.19:
无法添加唯一键属性“路径”设置为“ *”的类型为“添加”的重复收集条目
解决方案是在add
标记之前 add
以下行:
<remove path="*"/>
因此,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。
我注意到您正在引用Microsoft.WindowsAzure.Diagnostics Version = 1.8.0.0,该版本是十月Azure SDK的一部分,用于获取Azure侦听器。 您的项目中是否包含存储客户端库1.7? Azure诊断库1.8依赖于较旧的存储客户端库1.7(而非与SDK一起发布的2.0)
