Langchain Integration

This guide shows how to instrument LangChain applications with Percival/Patronus by installing the required packages and initializing the instrumentor.

pip install patronus
pip install langchain langchain_openai langgraph
pip install openinference-instrumentation-langchain
pip install opentelemetry-instrumentation-threading
pip install opentelemetry-instrumentation-asyncio

Once installed, you can import the following instrumentors:

from openinference.instrumentation.langchain import LangChainInstrumentor
from opentelemetry.instrumentation.threading import ThreadingInstrumentor
from opentelemetry.instrumentation.asyncio import AsyncioInstrumentor
 
import patronus
patronus.init(integrations=[LangChainInstrumentor(), ThreadingInstrumentor(), AsyncioInstrumentor()])
