asp.net-mvc-4 - Azure 诊断未将日志保存在 azure 表中

Question

仅检查 Windows azure sdk 2.0 中引入的新功能 - 启用诊断。

刚刚使用 MVC 4 Web 角色创建了一个新的 Azure 云项目，并从配置部分启用了诊断，但没有任何日志保存在 Azure 表上 - WADLogsTable、WADDiagnosticInfrastructureLogsTable。

诊断.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" />
    <CrashDumps container="wad-crash-dumps" />
  </Directories>
  <Logs bufferQuotaInMB="1024" scheduledTransferPeriod="PT1M" scheduledTransferLogLevelFilter="Verbose" />
  <WindowsEventLog bufferQuotaInMB="1024" scheduledTransferPeriod="PT1M" scheduledTransferLogLevelFilter="Verbose">
    <DataSource name="Application!*" />
  </WindowsEventLog>
</DiagnosticMonitorConfiguration>

服务定义.csdef

<?xml version="1.0" encoding="utf-8"?>
<ServiceDefinition name="AzureWebApp" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceDefinition" schemaVersion="2013-03.2.0">
  <WebRole name="MvcWebApp" 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" />
    </Imports>
  </WebRole>
</ServiceDefinition>

ServiceConfiguration.Cloud.cscfg

<?xml version="1.0" encoding="utf-8"?>
<ServiceConfiguration serviceName="AzureWebApp" xmlns="http://schemas.microsoft.com/ServiceHosting/2008/10/ServiceConfiguration" osFamily="3" osVersion="*" schemaVersion="2013-03.2.0">
  <Role name="MvcWebApp">
    <Instances count="1" />
    <ConfigurationSettings>
      <Setting name="Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString" value="UseDevelopmentStorage=true" />
    </ConfigurationSettings>
  </Role>
</ServiceConfiguration>

WebRole.cs——来自 MVC 应用程序

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Threading;
using Microsoft.WindowsAzure;
using Microsoft.WindowsAzure.Diagnostics;
using Microsoft.WindowsAzure.ServiceRuntime;

namespace MvcWebApp
{
    public class WebRole : RoleEntryPoint
    {
        public override void Run()
        {
            // This is a sample webrole implementation. Replace with your logic.

            while (true)
            {
                Thread.Sleep(10000);
                Trace.WriteLine("Working", "Information");
            }
        }

        public override bool OnStart()
        {
            // For information on handling configuration changes
            // see the MSDN topic at http://go.microsoft.com/fwlink/?LinkId=166357.

            Trace.WriteLine("Starting Web Role ...", "Information");

            return base.OnStart();
        }
    }
}

我期待 Trace.WriteLine 错误，即“正在启动 Web 角色...”和“正在工作”到保存在 azure 表 - WADLogsTable 中。

任何帮助将不胜感激。

谢谢

如果您部署 diagnostics.wadcfg 文件，则无需向 OnStart() 方法添加任何自定义检测代码。

问题出在包含 "DevelopmentStorage=true" 的 ServiceConfiguration.Cloud.cscfg 文件中 - 将其替换为您的真实存储帐户或确保您的部署工具做到了。
