# ThousandEyes for OpenTelemetry Data Model v2 - Traces

## Supported Test Types

### **Network & App Synthetics Tests**

{% hint style="info" %}
In the context of this page, a layer refers to the specific category of trace data generated by a ThousandEyes test that is available for export through OpenTelemetry.

### Tags as Attributes

ThousandEyes converts [tags](https://developer.cisco.com/docs/thousandeyes/list-tags/) from tests and associated Cloud and Enterprise Agents into OpenTelemetry `Resource` attributes. Each tag consists of a `key` and a corresponding `value`.

If a stream uses `tagMatch`, `tagMatch` selects which tests are included in the stream. It does not limit which supported tags are converted to attributes.

Tags are streamed as attributes unless the tag key is not compliant with the [OpenTelemetry naming conventions for attributes](https://opentelemetry.io/docs/specs/semconv/general/naming/#recommendations-for-application-developers) or matches a ThousandEyes reserved OpenTelemetry attribute name. ThousandEyes excludes those tags from the `Resource` attributes.

When a tag is converted to an attribute, the tag key becomes the attribute name. Some tags might have multiple values or be shared between tests and agents. These cases are handled as follows:

* **Single value**: If a tag key has only one value, the value is represented as `string_value`.
* **Multiple values**: If there are several values for the same key, the value is represented as `array_value`, with each associated value as a `string_value` element.
* **Shared tags**: If tests and Cloud or Enterprise Agents are assigned to the same tag, the unique set of values is provided as the attribute value.

For more information, see [Tags and OpenTelemetry Streams](/product-documentation/integration-guides/opentelemetry/tags-and-opentelemetry-streams.md).

#### Example

Consider the following scenario:

* A stream is configured with test `1234` and the following tags:
  * `branch:sfo`
  * `branch:nyc`
  * `team:netops`
* The following tags are associated with test `1234`:
  * `branch:sfo`
  * `branch:nyc`
  * `team:netops`
  * `cluster:analytics`
* The following tags are associated with the source agent used by test `1234`:
  * `branch:sfo`
  * `location:us`

The resulting attributes would be structured as follows:

```
{
  resource_spans {
    resource {
      attributes {
        key: "branch"
        value {
          array_value: {
            values: [
              {
                string_value: "sfo"
              },
              {
                string_value: "nyc"
              }
            ]
          }
        }
      }
      attributes {
        key: "team"
        value {
          string_value: "netops"
        }
      }
      attributes {
        key: "cluster"
        value {
          string_value: "analytics"
        }
      }
      attributes {
        key: "location"
        value {
          string_value: "us"
        }
      }
    }
  }
}
```

**Notes**:

* The `branch:sfo` tag is not added twice to the `Resource` because the key-value pair already exists in the attributes.

{% hint style="info" %}
Not all observability platforms support string arrays for attribute values. For example, New Relic and Splunk Observability Cloud do not support this format. If your backend does not support string arrays for attributes, the tag attribute or the data point might be excluded.
