Question

我有一个抛出异常的C＃天蓝色函数：

[FunctionName("Function1")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            throw new Exception("Helpful message");
        }

该异常被运行时捕获并重新引发。在应用程序洞察中，这与消息Exception while executing function: Function1和调用堆栈一起记录。我在任何地方都找不到“有用的消息”。

在Application Insights中，我看到了这一点，并且所有的Properties都没有“ Helpful message”文本：

调用堆栈显示错误的位置：

我当前的解决方法是：

[FunctionName("Function1")]
        public static async Task<IActionResult> Run(
            [HttpTrigger(AuthorizationLevel.Function, "get", "post", Route = null)] HttpRequest req,
            ILogger log)
        {
            try
            {
                throw new Exception("Helpful message");
            }
            catch (Exception e)
            {
                log.LogError(e, e.Message);
                throw e;
            }
        }

是否有比将其添加到每个功能更好的方法来获取“帮助消息”？

Answer 1

这是UX中的错误。它固定在3/28，应该在4/2左右。同时，您可以在Google Analytics（分析）中访问您的消息。

UX（修复之前）：

分析仍应显示消息：

修复后（仍在进行中）：

Answer 2

按照此doc，要查看详细消息，最好使用TrackException()方法。或使用您在问题中提到的方法。

以下2个示例在Azure门户的run.csx中使用TrackException()：

示例1，不使用try-catch块：

#r "Microsoft.ApplicationInsights"

using System;
using Microsoft.ApplicationInsights;

public static void Run(TimerInfo myTimer, ILogger log)
{
    var telemetry = new TelemetryClient();    

    log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
    log.LogInformation("a infor 567");    
    telemetry.TrackException(new Exception("Helpful message zzzzzz"));    

}

在azure门户中检查结果->应用程序见解：

示例2，使用try-catch块：

    #r "Microsoft.ApplicationInsights"

    using System;
    using Microsoft.ApplicationInsights;

    public static void Run(TimerInfo myTimer, ILogger log)
    {
        var telemetry = new TelemetryClient();

        try
        {
        log.LogInformation($"C# Timer trigger function executed at: {DateTime.Now}");
        log.LogInformation("a infor 567");
        throw new Exception("Helpful message hahaha yyyyyy");
        }
        catch (Exception ex)
        {
           telemetry.TrackException(ex);      
        }
    }

执行后，您可以在azure门户中检查异常->应用程序见解：

如果您使用Visual Studio开发功能应用，则只需修改上面的一些代码即可。
