Unable to reproduce sample from documentation

[mgrishkov]

Dear team, I've repeated all steps from "Monitor and diagnose an ASP.NET Core application on Service Fabric" till the paragraph "View telemetry and the App map in Application Insights". As described in documentation at the step I should see events in Azure Application Insight. Unfortunately, I didn't see anything. Debug output window shows following messages: Application Insights Telemetry (unconfigured): {"name":"Microsoft.ApplicationInsights.Dev.Request","time":"2017-11-29T08:55:26.8391314Z","tags":{"ai.application.ver":"1.0.0.0","ai.cloud.role":"fabric:/Voting/VotingData","ai.cloud.roleInstance":"131564192630191563","ai.operation.id":"17993589-47f0a8360afffd48","ai.operation.name":"GET VoteData/Get","ai.location.ip":"::1","ai.internal.sdkVersion":"aspnet5f:2.2.0-beta1","ai.internal.nodeName":"XXXXXX.XXXXXX.local"},"data":{"baseType":"RequestData","baseData":{"ver":2,"id":"|17993589-47f0a8360afffd48.","name":"GET VoteData/Get","duration":"00:00:00.1632013","success":true,"responseCode":"200","url":"http://localhost:53576/c27e2db5-828a-4a69-b69d-7ba70c1eacce/131564192630191563/c11387c2-1aee-4ffa-b91b-f2e1c1029541/api/VoteData","properties":{"ServiceFabric.ServiceName":"fabric:/Voting/VotingData","ServiceFabric.ApplicationTypeName":"VotingType","ServiceFabric.ServiceTypeName":"VotingDataType","ServiceFabric.PartitionId":"c27e2db5-828a-4a69-b69d-7ba70c1eacce","httpMethod":"GET","ServiceFabric.ApplicationName":"fabric:/Voting","ServiceFabric.ReplicaId":"131564192630191563","AspNetCoreEnvironment":"Development","DeveloperMode":"true","ServiceFabric.NodeName":"_Node_0"}}}} Microsoft.AspNetCore.Mvc.Formatters.Json.Internal.JsonResultExecutor: Information: Executing JsonResult, writing value System.Collections.Generic.List1[System.Collections.Generic.KeyValuePair2[System.String,System.Int32]].

Repository with sample you can see here.

P.S. I have to hide pc and domain name with XXXXXX.XXXXXX.local

Hey, Are there anyone?

Looks like PerfCounterCollector has trouble.

@SergeyKanzhelev @cijothomas @Dmitry-Matveev any idea how to diagnose this?

[SergeyKanzhelev]

@mgrishkov I see two separate issues here:

1. log says (unconfigured) meaning that instrumentation key was not set properly. Please make sure proper instrumentation key was set in ApplicationInsights.config or settings.json on this step. If it's settings.json - make sure it will be read and applied in your DI.

2. Invalid operation exception happening. This is just a debug message, not an unhandled error. It may be some AI infrastructure exception that does not affect the main application logic

[mgrishkov]

@SergeyKanzhelev you are right the cause of the error was invalid Application Insight configuration. Now everything works fine.
