Module http_tracer_provider

Source
Expand description

This module provides utilities for configuring and building an OpenTelemetry TracerProvider specifically tailored for use in AWS Lambda environments.

It includes:

  • HttpTracerProviderBuilder: A builder struct for configuring and initializing a TracerProvider.
  • get_lambda_resource: A function to create a Resource with Lambda-specific attributes.

The module supports various configuration options, including:

  • Custom HTTP clients for exporting traces
  • Enabling/disabling logging layers
  • Setting custom tracer names
  • Configuring propagators and ID generators
  • Choosing between simple and batch exporters

It also respects environment variables for certain configurations, such as the span processor type and the OTLP exporter protocol.

§Examples

use lambda_otel_utils::HttpTracerProviderBuilder;
use opentelemetry_sdk::trace::{TracerProvider, Tracer};

let tracer_provider: TracerProvider = HttpTracerProviderBuilder::default()
    .with_stdout_client()
    .enable_fmt_layer(true)
    .with_tracer_name("my-service")
    .with_default_text_map_propagator()
    .with_default_id_generator()
    .enable_global(true)
    .build()?;

This example demonstrates how to use the HttpTracerProviderBuilder to configure and build a TracerProvider with custom settings for use in a Lambda function.
