神秘？ Azure DaaS Web作业

标签： azure azure-devops azure-webjobs

这周，我注意到我的团队Azure门户网站上有连续的网络作业。

enter image description here团队中没有人说他们已经部署或熟悉它。我找到了这个博客：

https://azure.microsoft.com/en-ca/blog/daas/

引用了一些可能相关的内容，但是此页面上的某些链接似乎已消失。其中之一重定向您以检查Azure“诊断和解决问题”刀片。似乎已经对其UI进行了修改，尽管我从来没有真正需要使用此功能，所以我不习惯其所有以前/新功能吗？功能。

在这里，我发现了一些似乎有用的诊断工具和Azure App Service“自动修复”。我发现似乎没有任何东西依赖于此网络作业，并且Azure门户中我们的任何其他App Services都不存在“ DaaS”。

我可以禁用或删除它吗？对于连续不断地运行网络作业，我感到不舒服，因为我们团队中没有人知道它在做什么，或者似乎出于任何原因而需要。

我们会失去这些吗？新？诊断刀片的功能？这些功能似乎可用于没有Webapp的App Services。

其日志如下：

没有告诉我很多。如果这是一项新功能，或者我正在获得ABTested，或者您认为可以将其禁用/删除，请告诉我。谢谢。

4 个答案:

答案 0 :(得分：3)

与Microsoft一起开票后，他们告诉我，因为我已经浏览过“诊断和解决”刀片，因此该Webjob是自动创建的，以允许在那里使用预期的功能。

我最终并不需要这些选项，因此可以安全地禁用或删除它。它不会干扰我的应用程序，但是如果我什么都不做，我认为我至少应该禁用它。

禁用它之后，我没有遇到任何问题，也没有遇到用户问题。

答案 1 :(得分：3)

我遇到了同样的问题，在我的Web应用程序中，我有一个Web作业，突然我看到了另一个名为“ Daas”的Web作业。 因此，我感到非常惊讶，并与MS团队进行了讨论，然后我发现，如果您为Web应用程序激活了“ Dignosis工具”，那么Azure云会自动创建此“ Daas” Web作业。 基本上，它将监视您当前的Web应用程序是否存在任何问题或威胁。 因此，无需担心，它不会消耗应用程序的内存。

答案 2 :(得分：1)

我试图进入class TriangleView: UIView { override func draw(_ rect: CGRect) { let path = UIBezierPath.init(rightAngledTriangleInRect: rect, withOffset: 20.0) let shape = CAShapeLayer() shape.path = path.cgPath // Set the mask layer.mask = shape } } 页，但是该功能已已弃用，如screenshot所示。该页面还建议使用“诊断和解决”。因此，我相信可以删除DaaS。

现在，它可以像连续的DaaS WebJob一样工作，您可以将其从webjob中删除。您可以访问enter image description here Kudu，然后选择“工具”->“压缩推送部署”->“ App_Data”->“作业”->“连续”。如果有“ DaaS”，则可以单击-将其删除，就像pic一样。

如果您仍有疑问，请告诉我。

答案 3 :(得分：0)

这是有关DaaS和DaasRunner的更多信息

请注意，每当您通过诊断和解决问题刀片运行任何诊断工具时，它们都会通过DaaS网站扩展来收集数据，在此期间，它们取决于DaasRunner Web作业。对于诸如内存转储，.NET Profiler，CPU监视，Java Flight Recorder，自动修复等工具来说都是如此。

如果您浏览至“诊断和解决问题”刀片中的任何诊断工具，DaasRunner Web作业可能会重新出现。下面的文章中有更多详细信息

应该注意的是，DaaSRunner网络作业通常闲置无事。仅当调用诊断会话（如CPU监视会话）或手动数据收集会话（如Profiler，内存转储等）时，DaasRunner才会唤醒并开始收集该会话所需的数据，因此离开该会话完全无害。 DaasRunner Webjob处于运行状态。
