Hey there, @ArturasGrygelis! I'm here to help you with any bugs, questions, or contributions. Let's tackle this together!

Ensure that the necessary environment variables are set correctly. You need to set LANGCHAIN_TRACING_V2 and LANGCHAIN_API_KEY properly.

Here is how you can set them:

export LANGCHAIN_TRACING_V2="true"
export LANGCHAIN_API_KEY="your_api_key_here"

Or, if you are using a notebook:

import getpass
import os

os.environ["LANGCHAIN_TRACING_V2"] = "true"
os.environ["LANGCHAIN_API_KEY"] = getpass.getpass("Enter your API key: ")

Replace "your_api_key_here" with your actual API key.

Additionally, ensure that you are correctly initializing and running your agents or chains with the tracing enabled. Here are some examples:

For sequential tracing:

from langchain.agents import AgentType, initialize_agent, load_tools
from langchain_community.llms import OpenAI

os.environ["LANGCHAIN_TRACING"] = "true"

llm = OpenAI(temperature=0)
tools = load_tools(["llm-math", "serpapi"], llm=llm)
agent = initialize_agent(
    tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True
)
agent.run("Your question here")

For concurrent tracing:

import asyncio
from aiohttp import ClientSession
from langchain.agents import AgentType, initialize_agent, load_tools
from langchain_community.llms import OpenAI

os.environ["LANGCHAIN_TRACING"] = "true"
aiosession = ClientSession()
llm = OpenAI(temperature=0)
async_tools = load_tools(["llm-math", "serpapi"], llm=llm, aiosession=aiosession)
agent = initialize_agent(
    async_tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, verbose=True
)
tasks = [agent.arun("Your question here") for _ in range(3)]
await asyncio.gather(*tasks)
await aiosession.close()

For using the context manager with tracing V2:

from langchain.agents import AgentType, initialize_agent, load_tools
from langchain_community.chat_models import ChatOpenAI
from langchain_core.tracers.context import tracing_v2_enabled

llm = ChatOpenAI(temperature=0)
tools = load_tools(["llm-math", "serpapi"], llm=llm)
agent = initialize_agent(
    tools, llm, agent=AgentType.CHAT_ZERO_SHOT_REACT_DESCRIPTION, verbose=True
)
with tracing_v2_enabled():
    agent.run("Your question here")  # this should be traced

agent.run("Your question here")  # this should not be traced

Ensure that the environment variables and the tracing setup are correctly configured in your application ^[1][2][3].
