Question

我有Azure WebRolle的代码如下:

public override bool OnStart()
{
    setDiagnostics();

    TestClass test = new TestClass();

    return base.OnStart(); 
}

private void setDiagnostics()
{
    string wadConnectionString = "Microsoft.WindowsAzure.Plugins.Diagnostics.ConnectionString";
    CloudStorageAccount cloudStorageAccount = CloudStorageAccount.Parse(RoleEnvironment.GetConfigurationSettingValue(wadConnectionString));

    DeploymentDiagnosticManager deploymentDiagnosticManager = new DeploymentDiagnosticManager(cloudStorageAccount, RoleEnvironment.DeploymentId);
    RoleInstanceDiagnosticManager roleInstanceDiagnosticManager = cloudStorageAccount.CreateRoleInstanceDiagnosticManager(
        RoleEnvironment.DeploymentId,
        RoleEnvironment.CurrentRoleInstance.Role.Name,
        RoleEnvironment.CurrentRoleInstance.Id);

    DiagnosticMonitorConfiguration diagConfig = roleInstanceDiagnosticManager.GetCurrentConfiguration();

    if (diagConfig == null)
        diagConfig = DiagnosticMonitor.GetDefaultInitialConfiguration();

    diagConfig.WindowsEventLog.DataSources.Add("Application!*");
    diagConfig.WindowsEventLog.ScheduledTransferPeriod = TimeSpan.FromMinutes(1D);

    roleInstanceDiagnosticManager.SetCurrentConfiguration(diagConfig);

    DiagnosticMonitor.Start(wadConnectionString, diagConfig);
}

在我 TestClass 的构建器中,以下代码为:

EventLog.WriteEntry("TestClass", "Before the try", EventLogEntryType.Information);
try
{
    EventLog.WriteEntry("TestClass", "In the try", EventLogEntryType.Information);
    Int32.Parse("abc");
}
catch (Exception ex)
{
    EventLog.WriteEntry("TestClass", ex.Message, EventLogEntryType.Error);
}

出于某种原因,如果我在 < code> OnStart 方法上用一个断点以调试模式运行该代码,并以 < kbd> F11 运行该代码,这个代码效果很好。但是,如果我删除所有断点并运行它,我看不到我的 < strong> WADWindowsEventLogstable 中的任何事件日志条目。因此,这对我来说似乎是一个时间问题... 有人知道为什么我的代码要执行这个字句吗?

提前感谢!

Answer 1

问题在于 < code> EventLog. writeEntry () 方法。我使用源“ testClass” 作为事件Log 源。但我从未以启动任务创建此源, 但由于权限不足, 它没有记录我的条目。

所以解决方案: 创建一个有启动任务的源头, 或者使用跟踪信息。

尝试将您的 Testles class 创建从 RoleEntrypoint.OnStart () 移动到 < a href="public override void Run() { TestClass test = new TestClass(); base.Run(); }

Answer 3

当它被部署到阿祖尔时,这个角色是实际启动还是仅仅在初始化和繁忙之间循环?

如果问题与时间有关,则按时间将物品从例中转移到Azure存储处:

diagConfig.WindowsEventLog.ScheduledTransferPeriod = TimeSpan.FromMinutes(1D);

如果该实例在击中定时器之前重新启动,则没有东西被转到您的桌子上。

You ll need to make sure that you keep the application running for more than 1 minute.

You ll need to verify that the following setting is turned off (this might cause the logs to end up in a different place than you would expect them to, more information: http://michaelcollier.wordpress.com/2012/04/02/where-is-my-windows-azure-diagnostics-data/):
