Function init_tracing_with_fallbacks

Source 
pub fn init_tracing_with_fallbacks(
    log_level: Level,
    fallback_service_name: &'static str,
    fallback_service_version: &'static str,
) -> TracerProvider
Expand description

Initializes tracing with OpenTelemetry integration and fallback service information.

This function sets up a complete tracing infrastructure including:

  • A temporary subscriber for setup logging
  • Resource detection from environment variables with fallbacks
  • OTLP tracer provider initialization
  • Global propagator configuration
  • Final subscriber with both console output and OpenTelemetry export

§Arguments

  • log_level: The minimum log level for events
  • fallback_service_name: Default service name if not found in environment variables
  • fallback_service_version: Default service version if not found in environment variables

§Returns

A configured TracerProvider that should be kept alive for the duration of the application and passed to shutdown_tracer_provider on shutdown.

§Examples

use telemetry_rust::{init_tracing_with_fallbacks, shutdown_tracer_provider};
use tracing::Level;

let tracer_provider = init_tracing_with_fallbacks(Level::INFO, "my-service", "1.0.0");

// Your application code here...

shutdown_tracer_provider(&tracer_provider);

§Panics

This function will panic if:

  • The OTLP tracer provider cannot be initialized
  • The text map propagator cannot be configured
