我有一个非常简单的 WCF 服务设置为在 Azure Web 角色中运行。它工作不正常（预期），但我需要收集跟踪诊断以成功调试。有人可以确定我哪里出错了吗？
这是我的 web 角色的 web.config：
<?xml version="1.0"?>
<configuration>
<configSections>
</configSections>
<!-- To collect diagnostic traces, uncomment the section below or merge with existing system.diagnostics section.
To persist the traces to storage, update the DiagnosticsConnectionString setting with your storage credentials.
To avoid performance degradation, remember to disable tracing on production deployments. -->
<system.diagnostics>
<sources>
<source propagateActivity="true" name="System.ServiceModel" switchValue="Verbose,ActivityTracing">
<listeners>
<add name="AzureLocalStorage">
<filter type="" />
</add>
</listeners>
</source>

我只是一直盯着这个，心想：“我找不到任何问题！”。这是我的 ServiceDefinition.csdef：
<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="MyApp" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition">
<WebRole name="MyApp.Svc" vmsize="Small">
<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" />
<Import moduleName="Connect" />
</Imports>
<LocalResources>
<LocalStorage name="MyApp.Svc.svclog" sizeInMB="1000" cleanOnRoleRecycle="true" />
</LocalResources>
<Startup>
<Task commandLine="installStuff.cmd" executionContext="elevated">
<Environment>
<Variable name="EMULATED">
<RoleInstanceValue xpath="/RoleEnvironment/Deployment/@emulated" />
</Variable>
</Environment>
</Task>
</Startup>
</WebRole>
</ServiceDefinition>
最后，我的 ServiceConfiguration.Cloud.cscfg：
<?xml version="1.0" encoding="utf-8"?>
<ServiceConfiguration serviceName="MyApp" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="1" osVersion="*">
<Role name="MyApp.Svc">
<Instances count="1" />
<ConfigurationSettings>
<Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="DefaultEndpointsProtocol=https;AccountName=myaccountname;AccountKey=myaccountkey" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.ActivationToken" value="myactivationtoken" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.Refresh" value="" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.WaitForConnectivity" value="" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.Upgrade" value="" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.EnableDomainJoin" value="" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainFQDN" value="" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainControllerFQDN" value="" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainAccountName" value="" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainPassword" value="" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainOU" value="" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.Administrators" value="" />
<Setting name="Microsoft.WindowsAzure.Plugins.Connect.DomainSiteName" value="" />
</ConfigurationSettings>
</Role>
</ServiceConfiguration>
更新：还有我的 WebRole.cs：
using System;
using System.Collections.Generic;
using System.Linq;
using Microsoft.WindowsAzure;
using Microsoft.WindowsAzure.Diagnostics;
using Microsoft.WindowsAzure.ServiceRuntime;
using System.Diagnostics;
namespace MyApp.Svc
{
public class WebRole : RoleEntryPoint
{
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.
Trace.WriteLine("MyApp.Svc started", "Information");
return base.OnStart();
}
}
}
