Local OpenTelemetry Tracing Stack

Getting Started

1. Clone this repo.
2. Bring up the local dev stack with docker compose up from inside this directory.
3. Download the OpenTelemetry javaagent JAR and move it somewhere where it can be read by your app at runtime.
4. Start your JVM app with the following environment variables defined:
   1. JAVA_TOOL_OPTIONS=-javaagent:/path/to/javaagent/jar/from/prior/step/opentelemetry-javaagent.jar
   2. OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:4317
   3. OTEL_SERVICE_NAME=name_of_your_app
   4. OTEL_RESOURCE_ATTRIBUTES=deployment.environment=local
5. Explore your traces via the Jaeger UI on http://localhost:16686/

Note: depending on your platform you may need to use host.docker.internal instead of localhost to access the local Jaeger and OTel Collector instances.
