我正在捕获 ADO.Net 诊断 ETW，如SQL Server 2008 中的数据访问跟踪中所述。设置有效，生成了一个 ETL 文件，如果我使用tracerpt，我可以看到 ADO.Net 跟踪：

但是，如果我将相同的 ETL 加载到WPA中，我发现捕获的事件没有任何用处。来自此提供程序的所有事件都显示Event Name <Unknown>，Event Type Classic并且没有关于实际 ADO.Net 事件信息的信息（即 tracerpt CSV 输出中最右边的列）：

由于我捕获的所有其他数据都可以在 WPA 中进行分析，所以我想知道 ADO.Net 诊断提供程序有什么不同，即事件对 WPA 如此不透明？

Windows 性能分析器从注册表读取清单数据以解码事件。如果 WPA 无法获取数据，它只会显示提供程序以及<Unknown>任务名称和事件名称的 GUID。WPA（经典，遗留提供程序）不支持那些由 ADO 跟踪提供的托管对象格式 (MOF) 文件，但它看起来tracerpt.exe确实支持它。

对于 ETL 文件的原始分析以仅查找事件，我建议Perfview。

它有自己的解析器来获取解码事件：

在此处输入图像描述

<Event MSec= "26176,0393" PID="11304" PName="foo" TID="8336" EventName="AdoNetDiag/TextW"
  TimeStamp="09.02.17 16:47:39.338496" ID="Illegal" Version="0" Keywords="0x00000000" TimeStampQPC="1.241.241.278.025"

  Opcode="18" TaskGuid="7acdcac9-8947-f88a-e51a-24018f5129ef" Channel="0" PointerSize="4"
  CPU="1" EventIndex="1328680" TemplateType="DynamicTraceEventData">
  <PrettyPrint>
    <Event MSec= "26176,0393" PID="11304" PName="foo" TID="8336" EventName="AdoNetDiag/TextW" ProviderName="Bid2Etw_ADONETDIAG_ETW" ModID="0" msgStr="01:CONNECTED [526D0000]C:\Windows\Microsoft.Net\assembly\GAC_32\System.Data\v4.0_4.0.0.0__b77a5c561934e089\System.Data.dll  &quot;System.Data.SNI.1&quot; {C9996FA5-C06F-F20C-8A20-69B3BA392315}
    "/>
  </PrettyPrint>

因此使用 WPA 对事件的 CPU、磁盘、文件 io 和 Perfview 进行性能分析。
