# Telemetry

AvaTax app uses [Open Telemetry](https://opentelemetry.io/) (OTEL) protocol to send signals to your collector of choice.

caution

This feature is in the **Feature Preview** stage, which means that it is available for experimentation and feedback. However, it is still undergoing development and is subject to modifications. If you want to try it contact [our team](mailto:hello@saleor.io).

App automatically instruments several spans for you to provide useful insights into AvaTax app performance.

Attributes on spans follow [OpenTelemetry semantic conventions](https://opentelemetry.io/docs/specs/semconv/general/trace/).
