This is a fork of the OTel demo that shows how to configure Grafana Alloy instead of the OTel Collector.
Each branch builds on top of the previous branch, and changes a part of the stack's configuration.
This fork only supports running the minimal Docker demo for now:
make start-minimalIn some steps, the only component that needs restarting is Alloy, so there's a make command for that, too:
make restart-alloyGrafana Alloy's web UI is accessible on http://localhost:12345.
Along with the main branch, there are a few other branches pushed. The naming sticks to the format <number>-<description>, and they build on top of each other.
Thus, in order to see how the OTel Collector could be replaced by Grafana Alloy, go through the branches one after the other, restart the compose stack using the docker-compose.minimal.yml file, and observe the behavior.
[!NOTE] Grafana Alloy Crashes Some branches will not succeed in running Alloy. This is intended - move on to the next branch. ;)
git checkout 1-alloy-drop-in
make start-minimal
# observe behavior etc.
make stop-minimal
# check out next branch
git checkout 2-alloy-drop-in-fix-config
make start-minimal
This repository contains the OpenTelemetry Astronomy Shop, a microservice-based distributed system intended to illustrate the implementation of OpenTelemetry in a near real-world environment.
Our goals are threefold:
- Provide a realistic example of a distributed system that can be used to demonstrate OpenTelemetry instrumentation and observability.
- Build a base for vendors, tooling authors, and others to extend and demonstrate their OpenTelemetry integrations.
- Create a living example for OpenTelemetry contributors to use for testing new versions of the API, SDK, and other components or enhancements.
We've already made huge progress, and development is ongoing. We hope to represent the full feature set of OpenTelemetry across its languages in the future.
If you'd like to help (which we would love), check out our contributing guidance.
If you'd like to extend this demo or maintain a fork of it, read our fork guidance.
You can be up and running with the demo in a few minutes. Check out the docs for your preferred deployment method:
For detailed documentation, see Demo Documentation. If you're curious about a specific feature, the docs landing page can point you in the right direction.
We welcome any vendor to fork the project to demonstrate their services and adding a link below. The community is committed to maintaining the project and keeping it up to date for you.
To get involved with the project see our CONTRIBUTING documentation. Our SIG Calls are every other Wednesday at 8:30 AM PST and anyone is welcome.
