I have one asp.net core 3.1 console app which basically is a background jobs. I am able to log to the application insight. But there is one persistent log which is logging every 15 minutes which is.

AI: TelemetryChannel found a telemetry item without an InstrumentationKey. This is a required field and must be set in either your config file or at application startup.

I have gone through other SO answer and tried the recommended solution but still is am seeing this log. Some of the post I looked on are How to find the source of "TelemetryChannel found a telemetry item without an InstrumentationKey"
Using nlog with ApplicationInsightsTelemetryWorkerService in .net core 3.1 console app

Based on this recommendation I tried with below code.

                services.AddApplicationInsightsTelemetryWorkerService(
                    options =>
                        Configuration
                    .GetSection("ApplicationInsights")
                    .Bind(options)
                 );
   NLog.LogManager.Configuration.FindTargetByName<ApplicationInsightsTarget>("ai").InstrumentationKey
                = Configuration["ApplicationInsights:InstrumentationKey"].ToString();

And my app settings has config like below.

"ApplicationInsights": {
    "InstrumentationKey": "instrumentation-key",
    "DeveloperMode": false,
    "EnableRequestTrackingTelemetryModule": true,
    "EnableAdaptiveSampling": false,
    "EnableActiveTelemetryConfigurationSetup": true
  },

And package that i am using are

   <PackageReference Include="Microsoft.ApplicationInsights.NLogTarget" Version="2.14.0" />
   <PackageReference Include="Microsoft.ApplicationInsights.WorkerService" Version="2.15.0" />

Did anyone get luck fixing this issue?

1. Try to copy the appsettings.json to the application root folder during publishing.
2. Check by adding an application insight resource id to to the csproj:

 <ApplicationInsightsResourceId>/subscriptions/abc</ApplicationInsightsResourceId>

CodePudding user response：

Looks like this is the existing issue on the package version in 2.15.0 and above.

Microsoft.ApplicationInsights.WorkerService

I reverted the version back to 2.14.0. That fixed the issue for now.
