c# - 如何在 Windows Azure (MVC) 中记录错误和用户操作？

Question

Azure 变化如此之快，所以有人可以给我一些关于如何登录的建议吗:

• 错误
• 异常(exception)
• 用户操作

我希望能够将这些记录到表存储中，以便可以使用代码检索它们并在管理网页上查看它们。我并不是在寻找太多代码，但我真正想要的是知道我应该在哪里寻找。 Azure 变化如此之快，我想确保使用最好的。

谢谢

Azure 具有内置功能日志记录和跟踪，请参阅

以下是我自己使用 Azure 诊断的方法:

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>
