ApplicationInsights OperationId为空 [英] ApplicationInsights OperationId is empty

问题描述

我正在实现自定义ApplicationInsights记录器，并能够在跟踪，异常和请求等写入位置写入所有日志，但是OperationId在跟踪和异常中为空.

I'm implementing custom ApplicationInsights logger and able to write all logs in write places like traces, exceptions and request, but OperationId is empty in traces and exceptions.

昨天我在所有表中使用相同的代码并获取OperationId.之后，我在多线程方案中工作，效果不佳.现在，我再次从简单的代码开始，但是看不到OperationId.

Yesterday I was using same code and getting OperationId in all tables. After that I was playing for multi-thread scenario which didn't work well. Now I started again with simple code but can't see OperationId.

我的代码有什么问题?

public static class Function2
{
    private static TelemetryClient telemetryClient = new TelemetryClient(new Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration
    {
        InstrumentationKey = "********-****-********-****"
    });

    [FunctionName("Function2")]
    public static HttpResponseMessage Run([HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = null)]HttpRequestMessage req)
    {
        RequestTelemetry requestTelemetry = new RequestTelemetry { Name = "Function2" };
        var operation = telemetryClient.StartOperation(requestTelemetry);

        telemetryClient.TrackTrace("trace message", SeverityLevel.Error);
        telemetryClient.TrackException(new System.Exception("My custom exception"));


        operation.Telemetry.Success = true;
        telemetryClient.StopOperation(operation);

        return req.CreateResponse(HttpStatusCode.OK, "Hello ");
    }
}

推荐答案

此问题非常棘手，这是由于检测键设置所致.如果您使用 Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration (您在代码中使用过)来设置检测密钥，那么在应用程序见解中将不会显示operation_id.

This issue is very tricky, it's due to the instrumentation key setting. If you use Microsoft.ApplicationInsights.Extensibility.TelemetryConfiguration(you used in your code) to set instrumentation key, then no operation_id appears in app insights.

因此，请使用以下代码行设置检测键:

So please use this line of code to set instrumentation key:

TelemetryClient telemetryClient = new TelemetryClient() { InstrumentationKey = "your_key" };

我的示例代码如下，仅更改检测键设置方法:

My sample code as below, only change the instrumentation key setting method:

public static class Function1
{

    private static TelemetryClient telemetryClient = new TelemetryClient() { InstrumentationKey = "your_key" };

    [FunctionName("Function2")]
    public static HttpResponseMessage Run([HttpTrigger(AuthorizationLevel.Anonymous, "get", Route = null)]HttpRequestMessage req)
    {
        RequestTelemetry requestTelemetry = new RequestTelemetry { Name = "Function211" };
        var operation = telemetryClient.StartOperation(requestTelemetry);

        telemetryClient.TrackTrace("trace message 111", SeverityLevel.Error);
        telemetryClient.TrackException(new System.Exception("My custom exception 111"));

        operation.Telemetry.Success = true;
        telemetryClient.StopOperation(operation);

        return req.CreateResponse(HttpStatusCode.OK, "Hello ");
    }
}

执行后，您可以在azure门户中看到trace/exception的operation_id:

After executed, you can see the operation_id for trace / exception in azure portal:
