Module otel 

Available on crate feature otel only.

OpenTelemetry automatic instrumentation for distributed tracing.

Use the #[traced] macro to automatically instrument your functions:

use allframe::otel::traced;

#[traced]
async fn fetch_user(id: &str) -> User {
    // Automatically creates a span with function name
}

OpenTelemetry automatic instrumentation

This module provides automatic distributed tracing, metrics, and context propagation for AllFrame applications.

Features

• otel - Basic tracing support with the #[traced] macro
• otel-otlp - Full OpenTelemetry integration with OTLP export

Quick Start

use allframe_core::otel::Observability;

let _guard = Observability::builder("my-service")
    .service_version(env!("CARGO_PKG_VERSION"))
    .environment_from_env()
    .otlp_endpoint_from_env()
    .json_logging()
    .log_level_from_env()
    .build()?;

// Guard keeps the subscriber active
// When dropped, flushes pending spans
