### Langfuse Span Handler

[Langfuse](https://langfuse.com/docs) is an open source LLM engineering platform to help teams collaboratively debug, analyze and iterate on their LLM Applications. With the Langfuse integration, you can seamlessly track and monitor performance, traces, and metrics of your LlamaIndex application. Detailed traces of the LlamaIndex context augmentation and the LLM querying processes are captured and can be inspected directly in the Langfuse UI.

LlamaIndex provides a span handler for [Langfuse](https://langfuse.com/) which uses the instrumentation API instead of the legacy `CallbackManager`. To get started, [sign up](https://cloud.langfuse.com/auth/sign-up) and create a new project on Langfuse, then obtain an API key.

#### Usage Pattern

First install the Langfuse callback manager.

```
$ pip install llama-index-callbacks-langfuse
```

Then, create a span handler instance and add it to the dispatcher.

```py
import llama_index.core.instrumentation as inst
from llama_index.callbacks.langfuse import LangfuseSpanHandler

langfuse_span_handler = LangfuseSpanHandler(
public_key="<Your public key>",
secret_key="<Your secret key>",
host="<Host URL>",
)
dispatcher = inst.get_dispatcher()
dispatcher.add_span_handler(langfuse_span_handler)
```

## Other Partner `One-Click` Integrations (Legacy Modules)

These partner integrations use our legacy `CallbackManager` or third-party calls.
