Distributed Tracing with OpenTelemetry

This sample application shows how to implement distributed trancing using OpenTelemetry in golang and asp.net core.

Architecure

client

This is the entrypoint of the sample. This is a simple golang app calling the weather-service.

weather-service

Golang web server serving returning the weather description and temperature (obtained from the temperature-service) via gRPC. In case the location is not found, it returns an error instead.

temperature-service

Asp.net core web server returning random temperatures via HTTP.

Running

This sample uses Jaeger as the backend for distributed tracing. To start Jaeger run the following command:

docker run -d --name jaeger \
  -e COLLECTOR_ZIPKIN_HTTP_PORT=9411 \
  -p 5775:5775/udp \
  -p 6831:6831/udp \
  -p 6832:6832/udp \
  -p 5778:5778 \
  -p 16686:16686 \
  -p 14268:14268 \
  -p 14250:14250 \
  -p 9411:9411 \
