Support and Limitations

Support

ThousandEyes for OpenTelemetry currently supports the following test types and OpenTelemetry signals and metrics:

Test Type	Metrics	Signals
Agent-to-server	Latency, loss, jitter	metrics
Agent-to-agent	Latency, loss, jitter	metrics
BGP	Path changes, reachability, updates	metrics
HTTP server	Availability, response time, throughput	metrics
Web transaction	Page load time, transaction time, completion, errors	metrics, traces
Page load	Page load time, completion	metrics, traces
FTP server	Availability, response time, throughput	metrics
DNS server	Availability, resolution time	metrics
DNS Domain Trace	Availability, final query time	metrics
DNS DNSSEC Trace	Validity	metrics
RTP stream	MOS, loss, discards, latency	metrics
SIP server	Availability, response time, total time	metrics
Endpoint Agent network	Loss, latency, jitter	metrics
Endpoint Agent HTTP	Availability, response time, throughput	metrics
API	Time, completion	metrics

For more information about the supported test types, metrics and attributes, see ThousandEyes for OpenTelemetry Metrics.

BGP metrics are event-driven, which means that they are streamed only when there is an announcement or withdrawal of a prefix by a monitor.

Test Layers

ThousandEyes tests are composed of multiple layers (see Test Type Layers and Units for more details). When creating a test, multiple test types may be applied, depending on the configuration. For example, an HTTP server test includes metrics from the Web, Network (agent-to-server test), and BGP layers by default.

ThousandEyes for OpenTelemetry captures and sends metrics from all enabled test layers. Below is an example breakdown of the metrics for an HTTP server test:

• Web layer: Availability, Response Time, Throughput

• Network layer: Latency, Packet Loss, Jitter

• BGP layer: Path Changes, Reachability, Updates

Layer Configuration

The OpenTelemetry integration streams data from whichever layers are enabled on the underlying test. The integration itself does not configure or modify test layers.

If you need to customize which layers are active for different test types, you must update the test configuration using the ThousandEyes API. The examples below show how layer settings appear in the API request body. These apply to the test configuration, not the OpenTelemetry integration.

For full details, see the corresponding test API documentation.
