OpenTelemetry Sample

Demonstrates how to use OpenTelemetry tracing and metrics with the Ruby SDK

How to Run

First, in another terminal start up a Grafana OpenTelemetry instance which will collect telemetry and provide the Grafana UI for viewing the data.

  docker compose up

In another terminal, start the worker

  bundle exec ruby worker.rb

Finally start the workflow

  bundle exec ruby starter.rb

You should be able to see the result in the terminal.

To view the Grafana dashboard go to http://localhost:3000

You can find the trace by clicking on the "Explore" tab, selecting "Tempo" as the data source, and switching the query type to "Search".

There will be a trace for my-service containing the workflow trace.
