ThousandEyes for OpenTelemetry supports the following data model versions:

* [**Data Model Version 2**](https://docs.thousandeyes.com/product-documentation/integration-guides/opentelemetry/data-model/data-model-v2) is the default and recommended version for exporting telemetry data. OpenTelemetry trace and log signals require version 2.
