tonic-tracing-opentelemetry
Middlewares and tools to integrate tonic + tracing + opentelemetry for client and server.
Really early, missing lot of features, help is welcomed.
- Read OpenTelemetry header from the incoming requests
- Start a new trace if no trace is found in the incoming request
- Trace is attached into tracing's span
For examples, you can look at the examples folder.
Extract of client.rs
:
let channel = Channel::from_static("http://127.0.0.1:50051")
.connect()
.await?; //Devskim: ignore DS137138
let channel = ServiceBuilder::new()
.layer(OtelGrpcLayer::default())
.service(channel);
let mut client = GreeterClient::new(channel);
//...
opentelemetry::global::shutdown_tracer_provider();
Extract of server.rs
:
Server::builder()
// create trace for every request including health_service
.layer(server::OtelGrpcLayer::default().filter(filters::reject_healthcheck))
.add_service(health_service)
.add_service(reflection_service)
//.add_service(GreeterServer::new(greeter))
.add_service(GreeterServer::new(greeter))
.serve_with_shutdown(addr, shutdown_signal())
.await?;
