# Agno Instrumentation

> Instrument Agno agents with LangWatch’s Python SDK to send traces, analyze behaviors, and strengthen AI agent testing and evaluations.

<Tip>
  **Quick setup?** Instead of following these steps manually, [copy a prompt](/skills/code-prompts#instrument-my-code) into your coding agent and it will set this up for you automatically.
</Tip>

LangWatch integrates with Agno through OpenInference instrumentation to capture traces from your Agno agents automatically.

## Installation

<CodeGroup>
  ```bash pip theme={null}
  pip install langwatch agno openai openinference-instrumentation-agno
  ```

  ```bash uv theme={null}
  uv add langwatch agno openai openinference-instrumentation-agno
  ```
</CodeGroup>

## Usage

<Info>
  The LangWatch API key is configured by default via the `LANGWATCH_API_KEY` environment variable.
</Info>

Use the OpenInference instrumentation for Agno by passing `AgnoInstrumentor` to `langwatch.setup()`.

```python theme={null}
import langwatch
import os

from agno.agent import Agent
from agno.models.openai import OpenAIChat
from openinference.instrumentation.agno import AgnoInstrumentor

langwatch.setup(instrumentors=[AgnoInstrumentor()])

# Create and configure your Agno agent
agent = Agent(
    name="A helpful AI Assistant",
    model=OpenAIChat(id="gpt-5"),
    tools=[],
    instructions="You are a helpful AI Assistant.",
    debug_mode=True,
)

agent.print_response("Tell me a joke.")
```

The `AgnoInstrumentor` automatically captures all Agno agent activity. All traces will be sent to your LangWatch dashboard without requiring manual OpenTelemetry configuration.
