Crate azure_core_opentelemetry

Azure Core OpenTelemetry Tracing

This crate provides OpenTelemetry distributed tracing support for the Azure SDK for Rust. It bridges the standardized azure_core tracing traits with the OpenTelemetry for Rust implementation, enabling automatic span creation, context propagation, and telemetry collection for Azure services.

It allows Rust applications which use the OpenTelemetry APIs to generate OpenTelemetry spans for Azure SDK for Rust Clients.

OpenTelemetry integration with the Azure SDK for Rust

To integrate the OpenTelemetry APIs with the Azure SDK for Rust, you create a OpenTelemetryTracerProvider and pass it into your SDK ClientOptions.

use azure_core_opentelemetry::OpenTelemetryTracerProvider;
use opentelemetry_sdk::trace::SdkTracerProvider;
use std::sync::Arc;

// Create an OpenTelemetry tracer provider adapter from an OpenTelemetry TracerProvider
let otel_tracer_provider = Arc::new(SdkTracerProvider::builder().build());

let azure_provider = OpenTelemetryTracerProvider::new(otel_tracer_provider);

let options = ServiceClientOptions {
    client_options: ClientOptions {
        request_instrumentation: Some(RequestInstrumentationOptions {
            tracer_provider: Some(azure_provider),
        }),
        ..Default::default()
    },
    ..Default::default()
    };

If it is more convenient to use the global OpenTelemetry provider, then the OpenTelemetryTracerProvider::new_from_global_provider method will configure the OpenTelemetry support to use the global provider instead of a custom configured provider.

use azure_core_opentelemetry::OpenTelemetryTracerProvider;
use opentelemetry_sdk::trace::SdkTracerProvider;
use std::sync::Arc;


let azure_provider = OpenTelemetryTracerProvider::new_from_global_provider();

let options = ServiceClientOptions {
    client_options: ClientOptions {
        request_instrumentation: Some(RequestInstrumentationOptions {
            tracer_provider: Some(azure_provider),
        }),
        ..Default::default()
    },
};

Once the OpenTelemetryTracerProvider is integrated with the Azure Service ClientOptions, the Azure SDK will be configured to capture per-API and per-HTTP operation tracing options, and the HTTP requests will be annotated with W3C Trace Context headers.
