From opentelemetry-otlp@16: trait opentelemetry::trace::tracer::Tracer is not implemented for opentelemetry_sdk::trace::Tracer``

[frederikhors]

With these deps:

opentelemetry = { version = "0.22.0", default-features = false, features = [
    "trace",
] }
opentelemetry-http = { version = "0.11.1", default-features = false }
opentelemetry-otlp = { version = "0.15.0", default-features = false, features = [
    "http-proto",
] }
opentelemetry_sdk = { version = "0.22", default-features = false, features = [
    "rt-tokio",
] }

I'm using:

let otlp_tracer = opentelemetry_otlp::new_pipeline()
    .tracing()
    .with_exporter(exporter)
    .with_trace_config(trace::config().with_resource(Resource::new(vec![
        KeyValue::new("service.name", service_name.to_string()),
    ])))
    .with_batch_config(
        trace::BatchConfigBuilder::default()
            .with_max_export_batch_size(10_000)
            .with_max_queue_size(30_000)
            .with_scheduled_delay(Duration::from_millis(5_000))
            .build(),
    )
    .install_batch(opentelemetry_sdk::runtime::Tokio)
    .unwrap();

let layer = tracing_opentelemetry::layer()
    .with_tracer(otlp_tracer)
    .with_filter(EnvFilter::from("info"))
    .boxed();

and it works.

Now with these deps:

opentelemetry = { version = "0.23.0", default-features = false, features = [
    "trace",
] }
opentelemetry-http = { version = "0.12.0", default-features = false }
opentelemetry-otlp = { version = "0.16.0", default-features = false, features = [
    "http-proto",
] }
opentelemetry_sdk = { version = "0.23", default-features = false, features = [
    "rt-tokio",
] }

I'm getting this error:

How can I fix?

[zoer]

I had a similar problem and solved it by adjusting the crate versions. Here are the dependencies that worked for me:

tracing-subscriber = { version= "0.3.18", features = ["env-filter"]}
tracing = "0.1.40"
tracing-opentelemetry = "0.23.0"
opentelemetry-jaeger = { version = "0.21.0", features = ["full"] }
opentelemetry = "0.22.0"
opentelemetry_sdk = { version = "0.22.1", features = [ "rt-tokio", "rt-tokio-current-thread"] }
opentelemetry-jaeger-propagator = "0.1.0"
opentelemetry-otlp = { version = "0.15.0", features = ["tokio"]}
opentelemetry-semantic-conventions = "0.15.0"

[frederikhors]

Yeah, but I need opentelemetry = { version = "0.23.0" }.

It appears to be a version mismatch issue. The tracing-opentelemetry v0.23.0 is currently using OpenTelemetry v0.22:

https://github.com/tokio-rs/tracing-opentelemetry/releases/tag/v0.23.0

Upgrade to opentelemetry 0.22. Refer to the upstream

You will be able to use OpenTelemetry v0.23 only after tracing-opentelemetry releases a new version that supports it.

tracing-opentelemetry has been updated recently to the latest opentelemetry version. but that won't make the problem go away on your code base. There is an additonal steps added to build the tracer from OpenTelemetry pipeline I found out from a Pull Request opened for Actix-web Tracing.
https://github.com/LukeMathWalker/tracing-actix-web/pull/127/files

As you can see above the difference lies in the fact that, there are 2 lines added after getting the tracer with "expect". That's what fixes my build issue. i am not seeing this is documented. That's what return a Tracer with the right Trait bounds needed to fix the build errors:

    let tracer = opentelemetry_otlp::new_pipeline()
        .tracing()
        .with_exporter(exporter)
        .....
        .expect("Error: Failed to initialize the tracer.")
        .tracer_builder("Konbit")
        .build();

Here is the full code from the PR:

    let tracer = opentelemetry_otlp::new_pipeline()
        .tracing()
        .with_exporter(
            opentelemetry_otlp::new_exporter()
                .tonic()
        )
        .with_trace_config(Config::default().with_resource(
            Resource::new(vec![KeyValue::new(
                opentelemetry_semantic_conventions::resource::SERVICE_NAME,
                service_name.to_string(),
            )]))
        )
        .install_batch(opentelemetry_sdk::runtime::Tokio)
        .expect("Failed to install OpenTelemetry tracer.")
        .tracer_builder("Konbit")
        .build();

@douggynix I think you can shorten the .tracer_builder("name").build() bit to just .tracer("name")
