如何強制將diagnostics.wadcfg的內容反映在wad-control-container中

Question

我已經設置了一個診斷程序.wadcfg，其中包含很多性能計數器（90+）。但是，它沒有反映在wad-control - 容器一滴。我還確保該文件位於BIN文件夾下。

我webrole低於的OnStart代碼段（）：

// 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); 

是否有可能的OnStart（）邏輯優先，並覆蓋上diagnostics.wadcfg我的內容？

我diagnostics.wadcfg以下文件：

<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> 

感謝。

如果該部署的BLOB存儲中的wad-control-container中已存在文件，則角色和實例將優先。這樣，如果您要將該文件從外部修改爲系統，則該角色的回收不會丟失設置。

從MSDN Documentation：

「如果已經存在的WAD控制容器Blob存儲容器的XML配置 的.wadcfg文件將被忽略。」

優先順序可在http://msdn.microsoft.com/en-us/library/windowsazure/dn205146.aspx找到。

我的理解是，通過在您的解決方案中包含wadcfg文件，診斷子系統會選擇該文件並將其用作默認值。如果那裏沒有文件，則將該文件的副本放置在wad-control-container中。

需要注意的另一件事是您共享代碼來配置該性能計數器，但是您是否將該配置傳遞給該性能計數器？你可以發佈更多的OnStart用於處理診斷配置的任何代碼行嗎？
