I am trying to create a demo on my local to prove that I can setup auto instrumentation of dotnet 8 web api using Serilog sink to send data to OTEL collector which in turn is forwarding Trace, Metrics and Logs data to elastic APM agent in fleet-server.

**The Problem is that the APM services doesn't show a service named - DotNetWebAPI in APM Services in Kibana.**

I have setup the ELK stack using this article - [https://www.elastic.co/blog/getting-started-with-the-elastic-stack-and-docker-compose-part-2](https://www.elastic.co/blog/getting-started-with-the-elastic-stack-and-docker-compose-part-2)

# Version of Elastic products

STACK\_VERSION=8.8.2

I have loosely followed this article for dotnet 8 api, as it did not work with SSL, so i digressed a little, but the container is up and running and i can receive response from api endpoint in postman and can see the logs for it in the Kibana Logs Streams, but can't see the DotNetWebAPI in the APM services..

I have checked in my DotNetWebAPI code in this public repo - [GitHub - SunnyMittal/DotNetWebAPI](https://github.com/SunnyMittal/DotNetWebAPI/tree/master)

Elastic stack code is placed in this public repo -

Steps to reproduce the issue.

1. use any password to generate .net web api certs using below command **(use that password in ELK repo's .env file for variable - DOTNETWEBAPI\_CERT\_PASSWORD)**

```auto
dotnet dev-certs https -ep $env:USERPROFILE\.aspnet\https\aspnetapp.pfx -p localDevNetCore

```

1. Build the docker image say using below command from DotNetWebAPI project folder  
`docker build . --progress plain -t "tb1"`
2. Standup ELK stack using below docker command from ELK folder  
`docker compose up -d`
3. Browse to this url to trigger the API and then check logs in Kibana Stream  
[https://localhost:32774/api/WeatherForecast](https://localhost:32774/api/WeatherForecast)

Let me know if you need any further info.  
Thanks in advance for your help!
