armature-opentelemetry

OpenTelemetry integration for the Armature framework.

Features

• Distributed Tracing - Trace requests across services
• Auto Instrumentation - HTTP, database, cache spans
• Multiple Exporters - Jaeger, Zipkin, OTLP
• Context Propagation - W3C Trace Context, B3
• Baggage - Pass context across services

Installation

[dependencies]
armature-opentelemetry = "0.1"

Quick Start

use armature_opentelemetry::{init_tracer, TracingMiddleware};

#[tokio::main]
async fn main() {
    // Initialize tracer
    init_tracer("my-service", "http://localhost:4317").await;

    let app = Application::new()
        .with_middleware(TracingMiddleware::new())
        .get("/", handler);

    app.listen("0.0.0.0:3000").await.unwrap();
}

Custom Spans

use armature_opentelemetry::tracer;

async fn my_handler(req: HttpRequest) -> Result<HttpResponse, Error> {
    let span = tracer().start("process_request");

    // Do work...

    span.end();
    Ok(HttpResponse::ok())
}

Exporters

Jaeger

init_tracer_jaeger("my-service", "localhost:6831").await;

OTLP (OpenTelemetry Protocol)

init_tracer_otlp("my-service", "http://localhost:4317").await;
