splunk-otel-util-genai-translator-langsmith 0.1.1

Langsmith -> GenAI translator emitter for OpenTelemetry GenAI

This package provides automatic translation of Langsmith-specific span attributes to OpenTelemetry GenAI semantic convention compliant format.

Overview

Langsmith is the observability platform for LangChain applications, providing tracing, evaluation, and monitoring capabilities. This translator bridges Langsmith’s attribute format to the standardized GenAI semantic conventions.

Installation

pip install splunk-otel-util-genai-translator-langsmith

Usage

The translator automatically enables when the package is installed. No additional configuration is required.

To explicitly enable or configure:

from opentelemetry.util.genai.langsmith import enable_langsmith_translator

# Enable with default configuration
enable_langsmith_translator()

# Enable with custom attribute transformations
enable_langsmith_translator(
    attribute_transformations={
        "rename": {
            "my.custom.attr": "gen_ai.custom.attr"
        }
    }
)

Disabling Auto-Enable

Set the environment variable OTEL_INSTRUMENTATION_GENAI_LANGSMITH_DISABLE=true to disable automatic registration.
