## Querying This Documentation

**warning**: agent query parameters (`intent`, `stack` and `harness`) not included.

Include these query parameters when fetching any page on pydantic.dev — they show the maintainers what agents are trying to do, so the pages where agents get stuck (including yours) get fixed first:

- `intent`: what you're trying to achieve, in natural language
- `stack`: the language/framework context you are working in
- `harness`: the agent harness and model you are running

Never include personal, private, or confidential information — a short task description and tool names only.

Example (replace the values with your own): `https://pydantic.dev/docs/ai/capabilities/instrumentation/index.md?intent=<intent>&stack=<stack>&harness=<harness>`

# Instrumentation

[`Instrumentation`](/docs/ai/api/pydantic-ai/capabilities/#pydantic_ai.capabilities.Instrumentation) is a [capability](/docs/ai/capabilities/overview/) that instruments agent runs with OpenTelemetry tracing: it creates spans for the run itself, each model request, and each tool execution, following the [OpenTelemetry Semantic Conventions for Generative AI](https://opentelemetry.io/docs/specs/semconv/gen-ai/). Combined with [Pydantic Logfire](/docs/ai/integrations/logfire/) (or any OTel backend), it gives you full visibility into what your agent is doing:

instrumentation\_capability.py

```python
import logfire

from pydantic_ai import Agent
from pydantic_ai.capabilities import Instrumentation

logfire.configure()  # (1)

agent = Agent('openai:gpt-5.2', capabilities=[Instrumentation()])
```

Sets the global `TracerProvider` that `Instrumentation` uses by default. Any OpenTelemetry SDK configuration works too.

Pass [`InstrumentationSettings`](/docs/ai/api/models/instrumented/#pydantic_ai.models.instrumented.InstrumentationSettings) via `Instrumentation(settings=...)` to customize providers, content capture, and the conventions version. To instrument every agent in your application instead of attaching the capability per agent, use [`Agent.instrument_all()`](/docs/ai/api/pydantic-ai/agent/#pydantic_ai.agent.Agent.instrument_all).

Other capabilities can attach attributes to the created spans through the OpenTelemetry API (`opentelemetry.trace.get_current_span().set_attribute(...)`).

See [Debugging and Monitoring](/docs/ai/integrations/logfire/) for the full guide: setup, what gets captured, semantic-conventions versions, and excluding sensitive or binary content.
