Question

我想使用NLog和Azure诊断程序向现有的azure云服务添加日志记录，我完成了此处描述的所有步骤：http://msdn.microsoft.com/en-us/library/azure/dn482131.aspx

但是，遗憾的是，在测试云服务时，未创建WADLogsTable表存储，并且此处不存储任何信息。不是本地开发存储，也不是天蓝色。

diagnostics.wadcfg：

<?xml version="1.0" encoding="utf-8"?>
<DiagnosticMonitorConfiguration configurationChangePollInterval="PT1M" overallQuotaInMB="4096" xmlns="http://schemas.microsoft.com/ServiceHosting/2010/10/DiagnosticsConfiguration">
  <DiagnosticInfrastructureLogs />
  <Directories>
    <IISLogs container="wad-iis-logfiles" directoryQuotaInMB="1024" />
    <CrashDumps container="wad-crash-dumps" />
  </Directories>
  <Logs bufferQuotaInMB="1024" scheduledTransferPeriod="PT1M" scheduledTransferLogLevelFilter="Verbose" />
  <PerformanceCounters bufferQuotaInMB="512">
    <PerformanceCounterConfiguration counterSpecifier="\Memory\Available MBytes" sampleRate="PT3M" />
  </PerformanceCounters>
  <WindowsEventLog bufferQuotaInMB="1024" scheduledTransferPeriod="PT1M" scheduledTransferLogLevelFilter="Verbose">
    <DataSource name="Application!*" />
  </WindowsEventLog>
</DiagnosticMonitorConfiguration>

ServiceConfiguration.Local.csfg（Cloud上也一样，只有正确的表存储帐户）

<?xml version="1.0" encoding="utf-8"?>
<ServiceConfiguration serviceName="AAService" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="4" osVersion="*" schemaVersion="2014-01.2.3">
  <Role name="Web.Services.AAService">
    <Instances count="1" />
    <ConfigurationSettings>
      <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" />
    </ConfigurationSettings>
  </Role>
</ServiceConfiguration>

ServiceDefinition.csdef中

<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="AAService" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2014-01.2.3">
  <WebRole name="Web.Services.AAService" vmsize="ExtraSmall">
    <Sites>
      <Site name="Web">
        <Bindings>
          <Binding name="Endpoint1" endpointName="Endpoint1" />
        </Bindings>
      </Site>
    </Sites>
    <Endpoints>
      <InputEndpoint name="Endpoint1" protocol="http" port="80" />
    </Endpoints>
    <Imports>
      <Import moduleName="Diagnostics" />
    </Imports>
    <LocalResources>
      <LocalStorage name="Web.Services.AAService.svclog" sizeInMB="1000" cleanOnRoleRecycle="false" />
    </LocalResources>
  </WebRole>
</ServiceDefinition>

WebRole入口点

 public override bool OnStart()
        {
            // To enable the AzureLocalStorageTraceListner, uncomment relevent section in the web.config  
            DiagnosticMonitorConfiguration diagnosticConfig = DiagnosticMonitor.GetDefaultInitialConfiguration();
            diagnosticConfig.Directories.ScheduledTransferPeriod = TimeSpan.FromMinutes(1);
            diagnosticConfig.Directories.DataSources.Add(AzureLocalStorageTraceListener.GetLogDirectory());

            DiagnosticMonitor.Start("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString", diagnosticConfig);

            // For information on handling configuration changes
            // see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357.

            return base.OnStart();
        }

云服务web.config也有：

<system.diagnostics>
    <trace>
      <listeners>
        <add type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.Diagnostics, Version=2.3.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="AzureDiagnostics">
          <filter type="" />
        </add>
      </listeners>
    </trace>
  </system.diagnostics>

有没有人有任何想法为什么这不会产生任何跟踪日志？我将Trace.WriteLine（）称为应用程序通过的许多地方，但仍然没有WADLogsTable。

感谢您的帮助

摆脱OnStart中的所有Diagnostic *代码。 csdef中的<Import moduleName="Diagnostics" />将自动启动诊断代理程序，诊断代理程序将从.wadcfg中读取设置。您在OnStart中的代码是不必要的，并且由于加载WAD配置的优先顺序而覆盖了wadcfg设置。

另请注意，如果您尝试更新现有云服务，则需要先删除blob存储中的XML文件。如果blob存储中已存在文件，则诊断代理将忽略.wadcfg设置。您要查找的文件位于wad-control-container中，并使用部署ID和角色名称命名。

Azure诊断程序不会创建WADLogsTable
