LLMonitor

LLMonitor is an open-source observability platform that provides cost and usage analytics, user tracking, tracing and evaluation tools.

Setupโ€‹

Create an account on llmonitor.com, then copy your new app's tracking id.

Once you have it, set it as an environment variable by running:

export LLMONITOR_APP_ID="..."

If you'd prefer not to set an environment variable, you can pass the key directly when initializing the callback handler:

from langchain_community.callbacks.llmonitor_callback import LLMonitorCallbackHandler

handler = LLMonitorCallbackHandler(app_id="...")

Usage with LLM/Chat modelsโ€‹

from langchain_openai import OpenAI
from langchain_openai import ChatOpenAI

handler = LLMonitorCallbackHandler()

llm = OpenAI(
callbacks=[handler],
)

chat = ChatOpenAI(callbacks=[handler])

llm("Tell me a joke")

API Reference:OpenAI | ChatOpenAI

Usage with chains and agentsโ€‹

Make sure to pass the callback handler to the run method so that all related chains and llm calls are correctly tracked.

It is also recommended to pass agent_name in the metadata to be able to distinguish between agents in the dashboard.

Example:

from langchain_openai import ChatOpenAI
from langchain_community.callbacks.llmonitor_callback import LLMonitorCallbackHandler
from langchain_core.messages import SystemMessage, HumanMessage
from langchain.agents import OpenAIFunctionsAgent, AgentExecutor, tool

llm = ChatOpenAI(temperature=0)

handler = LLMonitorCallbackHandler()

@tool
def get_word_length(word: str) -> int:
"""Returns the length of a word."""
return len(word)

tools = [get_word_length]

prompt = OpenAIFunctionsAgent.create_prompt(
system_message=SystemMessage(
content="You are very powerful assistant, but bad at calculating lengths of words."
)
)

agent = OpenAIFunctionsAgent(llm=llm, tools=tools, prompt=prompt, verbose=True)
agent_executor = AgentExecutor(
agent=agent, tools=tools, verbose=True, metadata={"agent_name": "WordCount"} # <- recommended, assign a custom name
)
agent_executor.run("how many letters in the word educa?", callbacks=[handler])

Another example:

from langchain.agents import load_tools, initialize_agent, AgentType
from langchain_openai import OpenAI
from langchain_community.callbacks.llmonitor_callback import LLMonitorCallbackHandler


handler = LLMonitorCallbackHandler()

llm = OpenAI(temperature=0)
tools = load_tools(["serpapi", "llm-math"], llm=llm)
agent = initialize_agent(tools, llm, agent=AgentType.ZERO_SHOT_REACT_DESCRIPTION, metadata={ "agent_name": "GirlfriendAgeFinder" }) # <- recommended, assign a custom name

agent.run(
"Who is Leo DiCaprio's girlfriend? What is her current age raised to the 0.43 power?",
callbacks=[handler],
)

User Trackingโ€‹

User tracking allows you to identify your users, track their cost, conversations and more.

from langchain_community.callbacks.llmonitor_callback import LLMonitorCallbackHandler, identify

with identify("user-123"):
llm.invoke("Tell me a joke")

with identify("user-456", user_props={"email": "user456@test.com"}):
agent.run("Who is Leo DiCaprio's girlfriend?")
