RAI supports tracing capabilities to help monitor and analyze the performance of your AI models, at a minor performance cost. By default, tracing is off. This document outlines how to configure tracing for your RAI project.
Tracing configuration is managed through the config.toml
file. The relevant parameters for tracing are:
The project
field under the [tracing]
section sets the name for your tracing project. This name will be used to identify your project in the tracing tools.
Note
Project name is currently only used by LangSmith. Langfuse will upload traces to the default project.
Langfuse is an open-source observability & analytics platform for LLM applications.
To enable Langfuse tracing:
- Set
use_langfuse = true
in theconfig.toml
file. - Set the
LANGFUSE_PUBLIC_KEY
andLANGFUSE_SECRET_KEY
environment variables with your Langfuse credentials. - Optionally, you can specify a custom Langfuse host by modifying the
host
field under[tracing.langfuse]
.
LangSmith is a platform for debugging, testing, and monitoring LangChain applications.
To enable LangSmith tracing:
- Set
use_langsmith = true
in theconfig.toml
file. - Set the
LANGCHAIN_API_KEY
environment variable with your LangSmith API key.
To enable tracing in your RAI application, you need to import the get_tracing_callbacks() function and add it to the configuration when invoking your agent or model. Here's how to do it:
- First, import the get_tracing_callbacks() function:
from rai.utils.model_initialization import get_tracing_callbacks
- Then, add it to the configuration when invoking your agent or model:
response = agent.invoke(
input_dict,
config={"callbacks": get_tracing_callbacks()}
)
By adding the get_tracing_callbacks() to the config parameter, you enable tracing for that specific invocation. The get_tracing_callbacks() function returns a list of callback handlers based on your configuration in config.toml.
If you encounter issues with tracing:
- Ensure all required environment variables are set correctly.
- Check whether tracing is on by checking whether
use_langsmith
oruse_langfuse
flag is set totrue
inconfig.toml
. - Verify that you have the necessary permissions and valid API keys for the tracing services you're using.
- Look for any error messages in your application logs related to tracing initialization.
