我有一个写入EventHub的AspNetCore网络应用程序和一个从中读取的webjob。我希望此事务的两个部分中的遥测在Application Insights中具有相同的操作ID。
因此,当我要将数据发送到EventHub时,我尝试将操作ID从TelemetryClient中拉出来,例如。
var myOperationId = MyTelemetryClient.Context.Operation.Id;
但这总是让我无效。我找到了article并尝试使用
var request.HttpContext.Items["Microsoft.ApplicationInsights.RequestTelemetry"] as RequestTelemetry;
但是再次无效。在我需要的时候我可以提取这个值的任何指针吗?
我的代码如下所示:
public class Startup
{
public void ConfigureServices( IServiceCollection IServices )
{
var builder = TelemetryConfiguration.Active.TelemetryProcessorChainBuilder;
builder.Use((next) => new MyTelemetryProcessor(next));
builder.Build();
var aiOptions = new Microsoft.ApplicationInsights.AspNetCore.Extensions.ApplicationInsightsServiceOptions();
aiOptions.EnableQuickPulseMetricStream = true;
IServices.AddApplicationInsightsTelemetry( Configuration, aiOptions);
IServices.AddMvc();
IServices.AddOptions();
TelemetryClient AppTelemetry = new TelemetryClient();
AppTelemetry.InstrumentationKey = InsightsInstrumentationKey;
IServices.AddSingleton(typeof(TelemetryClient), AppTelemetry);
}
public void Configure( IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory )
{
app.UseApplicationInsightsRequestTelemetry();
app.UseApplicationInsightsExceptionTelemetry();
app.UseMvc();
var configuration = app.ApplicationServices.GetService<TelemetryConfiguration>();
configuration.TelemetryInitializers.Add(new MyTelemetryInitializer());
}
}
[Route("[controller]")]
public class MyController
{
private readonly TelemetryClient mTelemetryClient;
public MyController(
TelemetryClient TelemetryClientArg)
{
mTelemetryClient = TelemetryClientArg;
}
[HttpPost]
public async Task<IActionResult> Post([FromBody]MyPostDataClass MyPostData)
{
string telemetryId = mTelemetryClient.Context.Operation.Id; // this is null
return Ok();
}
}

想想我最终破解了这个而没有创建不必要的遥测。以下是针对AspNetCore的,但只要操作ID初始化程序可用,就应该进行转换:
var operationId = default(string);
try
{
var telemetry = new RequestTelemetry();
TelemetryConfiguration
.Active
.TelemetryInitializers
.OfType<OperationIdTelemetryInitializer>()
.Single()
.Initialize(telemetry);
operationId = telemetry.Context.Operation.Id;
}
catch { }

Asp.Net核心软件包有一个OperationIdTelemetryInitializer
(see github),它试图从请求中设置它。假设您有请求跟踪并且此遥测初始化程序已打开,则该请求中发生的所有内容都会设置Operation.Id。
如果它不适合您,您可以创建自己的自定义TelemetryInitializer
来设置它,无论您需要什么,或者,在您确定它为空的地方,您可以设置在那里,那个环境中的所有东西都应该有那个id。

您可以通过发送遥测数据然后从遥测对象读回操作ID来获取此值。不优雅,但它有效。
[HttpPost]
public async Task<IActionResult> Post([FromBody]MyPostDataClass MyPostData)
{
var dummyTrace = new TraceTelemetry("hello", SeverityLevel.Verbose);
mTelemetryClient.TrackTrace(dummyTrace);
string opId = dummyTrace.Context.Operation.Id;
return Ok();
}

我的OperationIdTelemetryInitializer
中没有TelemetryConfiguration .Active.TelemetryInitializers
。
但这为我提供了当前的操作ID:
System.Diagnostics.Activity.Current.RootId
