# opentelemetry-go-example

An example app where two Golang services collaborate on an http request. The timing of these requests are recorded using the OpenTelemetry SDK.

## Setup

* `make module build`

## Jaeger Exporter - view traces on the Jaeger UI

* `docker run -d -p 16686:16686 -p 14268:14268 jaegertracing/all-in-one`

* Execute the `frontend` and `backend` services on separate terminals.

  For example:

  * `./bin/opentelemetry-go-example backend`

  * `./bin/opentelemetry-go-example frontend`

* Generate traces:

  * `curl http://localhost:8081`

* ![Example Jaeger Trace](images/jaeger-screenshot.png?raw=true "Example Jaeger Trace")

## Zipkin Exporter - view traces on the Zipkin UI

* `docker run -d -p 9411:9411 openzipkin/zipkin`

* Execute the `frontend` and `backend` services on separate terminals.

  For example:

    * `EXPORTER=zipkin ./bin/opentelemetry-go-example backend`

    * `EXPORTER=zipkin ./bin/opentelemetry-go-example frontend`

* Generate traces:

    * `curl http://localhost:8081`

* ![Example Zipkin Trace](images/zipkin-screenshot.png?raw=true "Example Zipkin Trace")
