OpenTelemetry Automatic Instrumentation Example

You can find the source code here.

Firstly, download OpenTelemetry JVM agent JAR:

OTEL_AGENT_PATH=$(cs fetch --classpath "io.opentelemetry.javaagent:opentelemetry-javaagent:latest.release")

Then start Jaeger by running the following command:

docker run --rm -it \
  -e COLLECTOR_OTLP_ENABLED=true \
  -p 14250:14250 \
  -p 16686:16686 \
  -p 4317:4317 \
  jaegertracing/all-in-one:1.47

Then start the server application

sbt -J-javaagent:$OTEL_AGENT_PATH \
    -J-Dotel.service.name=example-server \
    -J-Dotel.traces.sampler=always_on \
    -J-Dotel.traces.exporter=otlp \
    -J-Dotel.metrics.exporter=none \
    "opentelemetryInstrumentationExample/runMain zio.telemetry.opentelemetry.instrumentation.example.ServerApp"

and the client application which will send one request to the server application

sbt -J-javaagent:$OTEL_AGENT_PATH \
    -J-Dotel.service.name=example-client \
    -J-Dotel.traces.sampler=always_on \
    -J-Dotel.traces.exporter=otlp \
    -J-Dotel.metrics.exporter=none \
    "opentelemetryInstrumentationExample/runMain zio.telemetry.opentelemetry.instrumentation.example.ClientApp"
