Question

我正在捕获ADO.Net诊断ETW，如Data Access Tracing in SQL Server 2008中所述。安装工作，生成一个ETL文件，如果我使用，我可以看到ADO.Net跟踪，比如tracerpt：

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。此提供商的所有事件都会显示Event Name <Unknown>，Event Type Classic，并且不会显示有关实际ADO.Net事件信息的信息（即，跟踪CSV输出中最右侧的列）：

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

Answer 1

Windows性能分析器从注册表中读取清单数据以解码事件。如果WPA无法获取数据，则它仅显示提供者的GUID，并显示任务名称和事件名称的<Unknown>。 WPA（经典，遗留提供商）不支持那些由ADO跟踪引起的Managed Object Format (MOF) files，但看起来tracerpt.exe确实支持它。

对于仅查找事件的ETL文件的原始分析，我建议Perfview。

它有自己的解析器来解码事件：

<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"
  Level="Always" ProviderName="Bid2Etw_ADONETDIAG_ETW" ProviderGuid="7acdcac8-8947-f88a-e51a-24018f5129ef" ClassicProvider="True"
  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。

WPA没有看到ETW事件数据，跟踪确实如此
