诊断数据需要很长时间才能记录在 Windows Azure 中

Question

我编写了一小段代码，通过单击不同的按钮，将收集不同类型的日志记录数据。但是，当我运行这段代码时，通过服务器资源管理器检查时通常不会反映记录的数据，即使记录了这些数据，也可以在很长一段时间（15-20 分钟）后查看。我在编写这段代码时是否犯了任何错误。该段代码如下：

    DiagnosticMonitorConfiguration diagMonitorConfiguration;
    RoleInstanceDiagnosticManager roleInstanceDiagnosticManager;
    protected void Page_Load(object sender, EventArgs e)
    {


        // Get the default initial configuration for DiagnosticMonitor.
        diagMonitorConfiguration = DiagnosticMonitor.GetDefaultInitialConfiguration();

        // Configures the transfer period for basic windows azure logs 
        diagMonitorConfiguration.Logs.ScheduledTransferPeriod = TimeSpan.FromSeconds(10);

        // Configures the log type to be Verbose
        diagMonitorConfiguration.Logs.ScheduledTransferLogLevelFilter = LogLevel.Verbose;

        // Start the diagnostics monitor
        //DiagnosticMonitor.Start(CloudStorageAccount.DevelopmentStorageAccount, diagConfig);

        //CloudStorageAccount storageAccount = CloudStorageAccount.Parse(RoleEnvironment.GetConfigurationSettingValue("Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString"));

        CloudStorageAccount storageAccount = CloudStorageAccount.DevelopmentStorageAccount;
        roleInstanceDiagnosticManager = storageAccount.CreateRoleInstanceDiagnosticManager(RoleEnvironment.DeploymentId, RoleEnvironment.CurrentRoleInstance.Role.Name, RoleEnvironment.CurrentRoleInstance.Id);

        //DiagnosticMonitorTraceListener tmpListener = new DiagnosticMonitorTraceListener();
        //System.Diagnostics.Trace.Listeners.Add(tmpListener);
    }

    // Used to trace custom warning messages
    protected void btnWarning_Click(object sender, EventArgs e)
    {
        // tracing user message as a warning
        System.Diagnostics.Trace.TraceWarning("WARNING ENCOUNTERED :" + TextBoxName.Text);
    }

    // tracing custom error messages 
    protected void btnError_Click(object sender, EventArgs e)
    {
        // To log the user message as an error
        .......TraceError("ERROR ENCOUNTERED :" + TextBoxName.Text);
    }

    // tracing custom information messages
    protected void btnInformation_Click(object sender, EventArgs e)
    {
        // To log the user message as mere information
        .........TraceInformation("INFORMATION SENT :" + TextBoxName.Text);
    }

    // used to enable diagnostic infrastructure logs to be collected
    protected void btnEnableInfrastructure_Click(object sender, EventArgs e)
    {
        // configuring the type and transfer period for the Infrastructure logs
        diagMonitorConfiguration.DiagnosticInfrastructureLogs.ScheduledTransferLogLevelFilter = some filter;
        diagMonitorConfiguration.DiagnosticInfrastructureLogs.ScheduledTransferPeriod = SOME TIME PERIOD            
        // Update the configuration setting for the diagnostic manager
        roleInstanceDiagnosticManager.SetCurrentConfiguration(diagConfig);
        Thread.Sleep(5000);

    }

    // used to enable crash dumps for the application
    protected void btnEnableCrashDumps_Click(object sender, EventArgs e)
    {
        //enabling crash dumps
        CrashDumps.EnableCollection(true);

        // Update the configuration setting for the diagnostic manager
        roleInstanceDiagnosticManager.SetCurrentConfiguration(diagConfig);
        Thread.Sleep(5000);
    }

    // used to enable the collection windows event logs
    protected void btnEnableEventLogs_Click(object sender, EventArgs e)
    {
        //Configuring the Windows Event logs
        diagMonitorConfiguration.WindowsEventLog.ScheduledTransferLogLevelFilter = LogLevel.Verbose;

        // two types of events, application and system data are logged
        diagMonitorConfiguration.WindowsEventLog.DataSources.Add("some source");

        // the time interval is configured as 5 seconds
        diagMonitorConfiguration.WindowsEventLog.ScheduledTransferPeriod = some time period;

        // Update the configuration setting for the diagnostic manager
        roleInstanceDiagnosticManager.SetCurrentConfiguration(diagConfig);
        Thread.Sleep(5000);
    }

    protected void btnEnablePerfCounters_Click(object sender, EventArgs e)
    {

        // configuring the performance counter data to be collected. processor time is collected
        diagMonitorConfiguration.PerformanceCounters.DataSources.Add(new PerformanceCounterConfiguration()
        {
            THE REQD PARAMETERS
        });

        // similarly available memory data is also logged
        diagMonitorConfiguration.PerformanceCounters.DataSources.Add(new PerformanceCounterConfiguration()
        {
            THE REQD PARAMETERS
        });

        // the scheduled time transfer is configured to 5seconds
        diagMonitorConfiguration.PerformanceCounters.ScheduledTransferPeriod = some time period;

        //DiagnosticMonitor.Start(CloudStorageAccount.DevelopmentStorageAccount, diagConfig);  USED PREVIOUSLY

        // Update the configuration setting for the diagnostic manager
        roleInstanceDiagnosticManager.SetCurrentConfiguration(diagConfig);
        Thread.Sleep(5000);
    }
}

Answer 1

IIRC，1 分钟似乎是最短的传输时间。完全不确定如果将其设置为较小的值会发生什么。您可以检查生成的控制文件（在 wad-control 容器中）并查看实际设置的传输速率。请记住，这是一个异步过程（记录、本地缓冲，然后传输）。如果您想要实时的东西，您需要调整跟踪侦听器以直接记录到表或 blob（或使用服务总线跟踪）。 查看调试培训工具包了解如何完成此操作。

Answer 2

根据 文档：

ScheduledTransferPeriod 属性用于设置传输频率
数据缓冲区将本地日志数据传输到持久存储。经过
默认情况下，没有为任何数据缓冲区设置此属性以防止
无意的存储成本。

您为此属性设置的值将四舍五入到最接近的值
分钟。因此，您可以指定的最短传输周期为 1
分钟。

不能肯定地说，但您多次调用 SetCurrentConfiguration()。上次我检查过，你只能调用一次。我不知道多次调用它会看到什么观察到的行为。我真的建议将所有诊断配置代码聚合到一个位置，也许在 global.asax 中，而不是分散在多个按钮处理程序中。
