This project consists of a Go client and server instrumented with Opentelemetry with the datadog-agent.
No actions are required other than spinning up the containers (see Docker Compose Section), as the client will automatically make GET /inject requests every 30 seconds.
The client and server spans will be part of a distributed trace, and both client and server produce a json log which is injected with the 128 bit trace_id.
Note: the trace_id and span_id are injected in the dd.trace_id and dd.span_id keys, as these are the keys in which the backend currently expects to see the trace_id/span_id documentation.
Retrieve your API_KEY from datadoghq, and expose your key on the shell:
export DD_API_KEY=xx
Bring up the client, server & datadog-agent:
docker-compose build
docker compose up
Spin down the client, server & datadog-agent:
docker compose down || Ctrl+C
