Using instrumentation libraries

When you develop an app, you might use third-party libraries and frameworks to accelerate your work. If you then instrument your app using OpenTelemetry, you might want to avoid spending additional time to manually add traces, logs, and metrics to the third-party libraries and frameworks you use.

Many libraries and frameworks already support OpenTelemetry or are supported through OpenTelemetry instrumentation, so that they can generate telemetry you can export to an observability back end.

If you are instrumenting an app or service that use third-party libraries or frameworks, follow these instructions to learn how to use natively instrumented libraries and instrumentation libraries for your dependencies.

Use natively instrumented libraries

If a library comes with OpenTelemetry support by default, you can get traces, metrics, and logs emitted from that library by adding and setting up the OpenTelemetry SDK with your app.

The library might require some additional configuration for the instrumentation. Go to the documentation for that library to learn more.

Use Instrumentation Libraries

Each instrumentation library is a crate.

For example, the instrumentation library for Actix Web will automatically create spans and metrics based on the inbound HTTP requests.
