Spring boot Open Telemetry Demo

This directory contains a Docker Compose environment that can be used to test Grafana Alloy.

NOTE: This environment is not intended for production use, and is maintained on a best-effort basis.

By default, only Grafana and databases are exposed:

• Grafana, for visualizing telemetry http://localhost:3000
• Grafana Mimir, for storing metrics http://localhost:9009
• Grafana Loki, for storing logs (localhost:3100)
• Grafana Tempo, for storing traces (localhost:3200)
• Grafana Pyroscope, for storing profiles (localhost:4040)
• Grafana Alloy, for receiving and exporting OTEL metrics, traces and logs http://localhost:12345

Grafana is automatically provisioned with the appropriate datasources and dashboards for monitoring Grafana Alloy.

To create Docker image of application, run the following command.

docker image build . -t spring-boot-observability-demo:0.0.1 -f Dockerfile

To start the environment, run:

docker compose up --build -d

To stop the environment, run:

docker compose down

Visualizing

To visualize Alloy data in Grafana, open http://localhost:3000 in a web browser.

NOTE: It can take up to a minute for Alloy metrics and profiles to start appearing.
