Tracing

Hyperledger Besu integrates with the open-telemetry project to integrate tracing reporting.

This allows reporting all JSON-RPC traffic as traces.

To try out this example, start the Open Telemetry Collector and the Zipkin service with:

$> docker-compose up

Start besu with:

$> OTEL_RESOURCE_ATTRIBUTES="service.name=besu-dev" OTEL_EXPORTER_OTLP_METRIC_INSECURE=true OTEL_EXPORTER_OTLP_SPAN_INSECURE=true ./gradlew run --args="--network=dev --rpc-http-enabled --metrics-enabled --metrics-protocol=opentelemetry"

Try interacting with the JSON-RPC API. Here is a simple example using cURL:

$> curl -X POST --data '{"jsonrpc":"2.0","method":"web3_clientVersion","params":[],"id":53}' http://localhost:8545

Open the Zipkin UI by browsing to http://localhost:9411/

You will be able to see the detail of your traces.
