This example shows basic span and metric usage, and exports to the OpenTelemetry Collector via OTLP.
By default runs against the otel/opentelemetry-collector-dev:latest image, and uses the tonic's
grpc example as the transport.
docker-compose up
or
docker-compose up -dIn another terminal run the application cargo run
Use the browser to see the trace:
- Jaeger at http://0.0.0.0:16686
Tear it down:
docker-compose downIf you don't want to use docker-compose, you can manually run the otel/opentelemetry-collector container
and inspect the logs to see traces being transferred.
# Run `opentelemetry-collector`
$ docker run -p4317:4317 otel/opentelemetry-collector:latest
# Report spans/metrics
$ cargo runYou should be able to see something similar below with different time and ID in the same console that docker runs.
