# Opentelemetry Experiment with .NET Core 3.x

[![OpenTelemetry Badge](https://img.shields.io/badge/OpenTelemetry-enabled-blue.svg)](http://opentelemetry.io)

This is a demo to show how to use OpenTelemetry for tracing on multiple services with multi-protocols on .NET Core 3.x

# Demo scenario

1. Web API (REST) - http://localhost:5000

2. WeatherService (gRPC) - http://localhost:5002

3. ProductService (REST) - http://localhost:5001

4. MeteoriteService (gRPC) - http://localhost:5003

### Step 1:

```

$ docker-compose up

```

### Step 2:

Then run 3 projects above with Visual Studio or Visual Code

### Step 3: Run `Web API` with url as below

[http://localhost:/WeatherForecast](http://localhost:/WeatherForecast)

## Jaeger UI

REST -> gRPC -> REST

[http://localhost:16686](http://localhost:16686/)

## Zipkin UI

REST -> gRPC -> REST

[http://localhost:9412](http://localhost:9412/)
