Question

我已经设置了一个带有大量性能计数器（90 +）的diagnostics.wadcfg。但是，它没有反映在wad-control-container blob上。我还确保此文件位于 BIN 文件夹下。

我的webrole在OnStart（）下面有代码片段：

   // Get the diagnostic monitor for the specified role instance.
RoleInstanceDiagnosticManager roleInstanceDiagnosticManager = 
         new RoleInstanceDiagnosticManager(myStorageAccount, 
                                           "28281fc7754b44faa9ccf4911983edf1",
                                           "MyWebRole",
                                           "deployment(1).MyAzureProject.WebRole1.0");

// Get the current diagnostic monitor for the role.
DiagnosticMonitorConfiguration currentConfiguration = roleInstanceDiagnosticManager.GetCurrentConfiguration();

// Use 30 seconds for the performance counter sample rate.
TimeSpan perfSampleRate = TimeSpan.FromSeconds(30.0);

// Add a performance counter for processor time to the current configuration.
currentConfiguration.PerformanceCounters.DataSources.Add(new PerformanceCounterConfiguration()
{
      CounterSpecifier = @"\Processor(_Total)\% Processor Time",
      SampleRate = perfSampleRate
});

// Apply the modified configuration to the diagnostic monitor for the role instance.
roleInstanceDiagnosticManager.SetCurrentConfiguration(currentConfiguration);

OnStart（）逻辑是否优先并覆盖diagnostics.wadcfg上的内容？

我的diagnostics.wadcfg文件如下：

<DiagnosticMonitorConfiguration
  xmlns="http://schemas.microsoft.com/ServiceHosting/2010/10/DiagnosticsConfiguration"
  configurationChangePollInterval="PT1M"
  overallQuotaInMB="8192">

  <PerformanceCounters bufferQuotaInMB="100" scheduledTransferPeriod="PT1M">

    <!-- 1. AZURE_ASP_NET -->
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\Application Restarts" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\Applications Running" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\Request Execution Time" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\Requests Current" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\Requests Disconnected" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\Requests Queued" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\Requests Rejected" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\Request Wait Time" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\State Server Sessions Abandoned" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\State Server Sessions Active" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\State Server Sessions Timed Out" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\State Server Sessions Total" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\Worker Processes Running" sampleRate="PT30S" />
    <PerformanceCounterConfiguration counterSpecifier="\ASP.NET\Worker Process Restarts" sampleRate="PT30S" />

  </PerformanceCounters>

</DiagnosticMonitorConfiguration>

感谢。

如果该部署的BLOB存储中的wad-control-container中已存在文件，则角色和实例将优先。这样，如果您在系统外部修改该文件，则角色的回收不会丢失设置。

来自MSDN Documentation：

“如果已有XML配置，则忽略.wadcfg文件在wad-control-container blob存储容器中。“

优先顺序可以在http://msdn.microsoft.com/en-us/library/windowsazure/dn205146.aspx找到。

我的理解是，通过在解决方案中包含wadcfg文件，诊断子系统会选择该文件并将其用作默认值。然后，如果那里没有文件，则将该文件的副本放在wad-control-container中。

另外需要注意的是，您共享了配置该性能计数器的代码，但是您是否已通过该配置？您是否可以针对处理诊断配置的任何代码行发布更多OnStart？

如何强制将diagnostics.wadcfg的内容反映在wad-control-container中
