如何在Windows Azure（MVC）中记录错误和用户操作？

Question

Azure的变化如此之快，因此可能有人给我我怎么可能会登录一些建议：

例外

用户操作

我希望能够

• 错误将这些日志记录到表格存储中，以便使用代码检索并在管理网页上查看。我对代码没有太多的了解，但我真正想要的是知道我应该在哪里看。 Azure变化如此之快我想确保使用最好的。

  谢谢

Answer 1

我只是做了上周末类似的东西。我最终创建了一个名为“LogEvents”的表，并使用提供者密钥来分隔不同类型的日志事件和日期（例如，11月21日有人登录时ProviderKey =“20111121_LoginEvent”）。

对我来说，查询然后可以很容易地对日期/类型来完成和管理页面

不知道这是最好的方式，但它似乎是为我工作的显示结果。我确实搜索了Google，但找不到真正做到这一点的任何内容。

更新1： 我使用的类被称为的LogEvent：

public class LogEntry : TableServiceEntity 
{ 
    public LogEntry(string logType) 
    { 
     if (LogType == null || LogType.Length == 0) 
     { 
      if (logType.Length > 0) 
       LogType = logType; 
      else 
       LogType = "Default"; 
     } 

     PartitionKey = string.Format("{0}_{1}", LogType, DateTime.UtcNow.ToString("yyyyMMdd")); 
     RowKey = string.Format("{0:10}_{1}", DateTime.MaxValue.Ticks - DateTime.Now.Ticks, Guid.NewGuid()); 
    } 

    public LogEntry() 
    { 

    } 

    public string Message { get; set; } 
    public DateTime LogDateTime { get; set; } 
    public string LogType { get; set; } 

} 

我只是创建它的一个新的实例并设置属性：

LogEntry le = new LogEntry("Default") { Message = "Default Page Loaded", LogDateTime=DateTime.Now }; 
     LogEntryDataSource ds = new LogEntryDataSource(); 
     ds.AddLogEntry(le); 

获取数据退出我只是使用标准的Linq查询并通过日期和LogType：

public IEnumerable<LogEntry> GetLogEntries(string eventType, DateTime logDate) 
    { 
     var results = from g in this.context.LogEntry 
         where g.PartitionKey == String.Format("{0}_{1}", eventType, logDate.ToString("yyyyMMdd")) 
         select g; 
     return results; 
    } 

有可能是一个更好的办法，但是这是非常简单的设置，它的工作对我来说

下面是我使用Azure诊断自己：

代码：

using System; 
using Microsoft.WindowsAzure.Diagnostics; 

namespace CrossCuttingConcerns 
{ 
    /// <summary> 
    /// This class handles diagnostics and stores the logs in the Azure table and blog storage. 
    /// Note: Basically all logs are turned on here, this can be expensive and you may want to change several settings here before going live 
    /// </summary> 
    public class AzureDiagnostics 
    { 
     /// <summary> 
     /// Sets how often diagnostics data is transferred to the Azure table storage or blob storage 
     /// Note: Change to a period that fits your need, commenting out one of these lines disables it 
     /// </summary> 
     /// <param name="diagnosticMonitorConfiguration"></param> 
     void SetDiagnositcManagerScheduledTransferPeriods(DiagnosticMonitorConfiguration diagnosticMonitorConfiguration) 
     { 
      diagnosticMonitorConfiguration.Directories.ScheduledTransferPeriod = TimeSpan.FromMinutes(5); 
      diagnosticMonitorConfiguration.Logs.ScheduledTransferPeriod = TimeSpan.FromMinutes(5); 
      diagnosticMonitorConfiguration.WindowsEventLog.ScheduledTransferPeriod = TimeSpan.FromMinutes(5); 
      diagnosticMonitorConfiguration.DiagnosticInfrastructureLogs.ScheduledTransferPeriod = TimeSpan.FromMinutes(5); 
      diagnosticMonitorConfiguration.PerformanceCounters.ScheduledTransferPeriod = TimeSpan.FromMinutes(5); 
     } 

     /// <summary> 
     /// Will add a full crashdump. 
     /// Note: Full crashdumps are not available in asp.net roles 
     /// </summary> 
     void AddFullCrashDumps() 
     { 
      CrashDumps.EnableCollection(true); 
     } 

     /// <summary> 
     /// Enables performance counters 
     /// Note: PerformanceCounterConfiguration.CounterSpecifier is language specific and depends on your OS language. 
     /// Note: For a complete list of possible PerformanceCounterConfiguration.CounterSpecifier values run "typeperf.exe /Q" 
     /// </summary> 
     /// <param name="diagnosticMonitorConfiguration"></param> 
     void AddPerformanceCounterMonitoring(DiagnosticMonitorConfiguration diagnosticMonitorConfiguration) 
     { 
      var performanceCounterConfiguration = 
       new PerformanceCounterConfiguration 
       { 
        CounterSpecifier = @"\Processor(*)\% Processor Time", 
        SampleRate = TimeSpan.FromSeconds(15) 
       }; 

      diagnosticMonitorConfiguration.PerformanceCounters.DataSources.Add(performanceCounterConfiguration); 
     } 

     /// <summary> 
     /// By default all Windows events to the Application and System logs are stored in the Azure table storage 
     /// Note: Decide here what Windows event logs you are interested in seeing, you can also filter out events 
     /// </summary> 
     /// <param name="diagnosticMonitorConfiguration"></param> 
     void AddEventLoggingFromWindowsEventLog(DiagnosticMonitorConfiguration diagnosticMonitorConfiguration) 
     { 
      // Syntax: <channel>!XPath Query 
      // See: http://msdn.microsoft.com/en-us/library/dd996910(VS.85).aspx 
      diagnosticMonitorConfiguration.WindowsEventLog.DataSources.Add("Application!*"); 
      diagnosticMonitorConfiguration.WindowsEventLog.DataSources.Add("System!*"); 
     } 

     void StartDiagnosticManager(DiagnosticMonitorConfiguration diagnosticMonitorConfiguration) 
     { 
      DiagnosticMonitor.Start("DiagnosticsConnectionString", diagnosticMonitorConfiguration); 
     } 

     public void EnableAzureDiagnostics() 
     { 
      var diagnosticMonitorConfiguration = DiagnosticMonitor.GetDefaultInitialConfiguration(); 

      SetDiagnositcManagerScheduledTransferPeriods(diagnosticMonitorConfiguration); 

      AddFullCrashDumps(); 
      AddPerformanceCounterMonitoring(diagnosticMonitorConfiguration); 
      AddEventLoggingFromWindowsEventLog(diagnosticMonitorConfiguration); 

      StartDiagnosticManager(diagnosticMonitorConfiguration); 
     } 
    } 
} 

配置：

<system.diagnostics> 
    <trace> 
     <listeners> 
     <add type="Microsoft.WindowsAzure.Diagnostics.DiagnosticMonitorTraceListener, Microsoft.WindowsAzure.Diagnostics, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" name="AzureDiagnostics"> 
     </add> 
     </listeners> 
    </trace> 
    </system.diagnostics>

已经有进一步改变Azure的日志记录....

通过Trace.TraceXXXX（例如Trace.TraceInformation）记录现在将被记录到Windows Az ure文件系统（〜\ LogFiles \ Application * .txt）。

您需要通过ftp访问网站（通过Azure管理门户/ Dashboard/Deployment Credentials启用）来查看这些文件。

必须首先从Web站点的Settings页面启用日志记录，您可以从Visual Studio（服务器浏览器/ Windows Azure网站/站点名称/视图设置）或Azure管理门户（在Configure /应用程序诊断/应用程序日志记录）。

这些日志也可以从Visual Studio输出窗口的实时Windows web Azure站点中看到（如果右键单击“确定”，则在“显示输出源”下拉列表中选择“Windows Azure Logs-xxx”）在Visual Studio服务器资源管理器（在Windows Azure网站下）中选择“在输出窗口中查看流式传输日志”。

登录到Visual Studio Output窗口是覆盖在斯科特谷的博客（http://weblogs.asp.net/scottgu/archive/2013/04/30/announcing-the-release-of-windows-azure-sdk-2-0-for-net.aspx）

注：我只在VS2012尝试这个。不知道它是否也适用于VS2010。
