ThousandEyes for OpenTelemetry Data Models

This section outlines how ThousandEyes integrates with OpenTelemetry (OTel) by representing telemetry data in the OTel format.

ThousandEyes for OpenTelemetry supports the following data model versions:

• Data Model Version 1

• Data Model Version 2 (Default)

Recommended Usage

• Version 2: This is the default and recommended version for exporting telemetry data to all observability backends except Grafana/Prometheus for metrics. OpenTelemetry trace signals are supported in version 2.

• Version 1: For streaming metrics to Grafana/Prometheus, we recommend you use version 1 of the data model, due to current limitations in handling resource attributes. For more information on these limitations, see OTEL metrics’ resources attributes gets dropped when exported to Grafana cloud. Note that Prometheus is actively working on native support for resource attributes.
