# ASP.NET Core observability w/ Grafana OSS Stack
Sample application showing how to write up ASP.NET Core with OpenTelemetry and export to Prometheus, Loki, and Tempo using the OpenTelemetry Collector
## Prerequisites
* [.NET SDK v7.0+](https://get.dot.net/)
* [Docker Desktop](https://www.docker.com/products/docker-desktop/)
## Setup
The demo is made up of a few projects written in C#.
* [Web API](src/BackendApiService) - Backend HTTP Weather API built with ASP.NET Core
* [Website](src/MainService) - Front facing UI using the default Blazor Server template
### Configured Ports 🔌
| Application | Port(s) |
|-------------------------|------------|
| Web API | 5006 |
| Website | 5238 |
| Loki | 3100 |
| Prometheus UI | 9090 |
| Grafana UI | 3000 |
| OpenTelemetry Collector | 4317, 4318 |
### Running the demo 🚀
Run the infrastructure components with the provided [docker-compose.yml](./docker-compose.yml) file.
```shell
> docker compose -p grafana-demo up
```
> 👀 This setup will create a **./tmp/** folder in the root of the project folder that will be mounted as a volume
> in the infrastructure containers.
Start both .NET applications
Backend Web API
```shell
> cd src/BackendApiService
> dotnet run
```
Front facing web API
```shell
> cd src/MainService
> dotnet run
```
