JavaScript Azure函数堆栈跟踪没有我的代码

Question

我有一个简单的Azure功能，我正在抛出异常。

它是由throw new Error('Oh no... we hit an edge case')组成的一行

奇怪的是，我的stacktrace只是一些.NET堆栈跟踪

更奇特的是，我可以清楚地看到我的堆栈跟踪已被捕获到某处。即使我检查或取消选中“只是我的代码”，我也没有得到任何可以显示我的错误+堆栈跟踪的内容

所以当然我的问题是：如何在appinsights中看到我的错误和代码的堆栈跟踪？

Answer 1

当函数将异常传递给ApplicaitonInsights时，它是一个外部异常，其InnerException来自用户代码。如果这是正确的话，我已经开始讨论了：https://github.com/Azure/azure-webjobs-sdk/issues/2156

对于javascript函数，它更有趣：内部异常的消息包含特定于语言的异常，例如：

Result: Failure
Exception: Oh no... we hit an edge case
Stack: 

ApplicationInsights SDK / logger发送所有这些信息，如果你去分析，你会在parsedStack [1]的exception.details中看到你的异常，只需运行类似的东西

exceptions | where tostring(details) contains "Oh no... we hit an edge case"

另一方面，门户网站不显示innermostType，innermostMessage或内部异常消息。请将反馈发送给门户团队！

Answer 2

要在应用程序洞察中记录您的异常，只需像正常一样使用context.log而不是抛出它。

try {
some code...
} 
catch (error) {
context.log('Error getting content' + error)
}

您看到的堆栈跟踪实际上来自函数主机，因为它是用.net核心编写的

Answer 3

要获取特定于您的应用程序的诊断数据，您可以插入代码以发送您自己的遥测数据。

你有几个选择：

•TrackEvent()通常用于监视使用模式，但它发送的数据也会显示在诊断搜索中的自定义事件下。事件已命名，并且可以包含字符串属性和数字度量标准，您可以在其上过滤诊断搜索。

•TrackTrace()允许您发送更长的数据，如POST信息。

•TrackException()发送堆栈跟踪。更多关于例外。

•如果您已经使用Log4Net或NLog等日志框架，则可以捕获这些日志，并在诊断搜索中查看它们以及请求和异常数据。

要查看这些事件，请打开“搜索”，打开“筛选”，然后选择“自定义事件”，“跟踪”或“例外”。

捕获异常和相关诊断数据

首先，您不会在门户网站中看到导致应用程序出现故障的所有异常。您将看到任何浏览器异常。但大多数服务器异常都被IIS捕获，您必须编写一些代码才能看到它们。您可以：

•通过在异常处理程序中插入代码来显式记录异常，以报告异常。

•通过配置ASP.NET框架自动捕获异常。对于不同类型的框架，必要的添加是不同的。跟踪代码中异常的最简单方法

try
    { ...
    }
    catch (ex)
    {
      appInsights.trackException(ex, "handler loc",
        {Game: currentGame.Name,
         State: currentGame.State.ToString()});
    }


var telemetry = new TelemetryClient();
    ...
    try
    { ...
    }
    catch (Exception ex)
    {
       // Set up some properties:
       var properties = new Dictionary <string, string>
         {{"Game", currentGame.Name}};

       var measurements = new Dictionary <string, double>
         {{"Users", currentGame.Users.Count}};

       // Send the exception telemetry:
       telemetry.TrackException(ex, properties, measurements);
    }

在Javascript中

const appInsights = require("applicationinsights");
appInsights.setup();
const client = appInsights.defaultClient;

module.exports = function (context, req) {
    context.log('JavaScript HTTP trigger function processed a request.');

    client.trackEvent({name: "my custom event", tagOverrides:{"ai.operation.id": context.invocationId}, properties: {customProperty2: "custom property value"}});
    client.trackException({exception: new Error("handled exceptions can be logged with this method"), tagOverrides:{"ai.operation.id": context.invocationId}});
    client.trackMetric({name: "custom metric", value: 3, tagOverrides:{"ai.operation.id": context.invocationId}});
    client.trackTrace({message: "trace message", tagOverrides:{"ai.operation.id": context.invocationId}});
    client.trackDependency({target:"http://dbname", name:"select customers proc", data:"SELECT * FROM Customers", duration:231, resultCode:0, success: true, dependencyTypeName: "ZSQL", tagOverrides:{"ai.operation.id": context.invocationId}});
    client.trackRequest({name:"GET /customers", url:"http://myserver/customers", duration:309, resultCode:200, success:true, tagOverrides:{"ai.operation.id": context.invocationId}});

    context.done();
};

这是一篇非常好的文章，解释了应用程序洞察如何工作以及如何配置自定义事件跟踪
