This article outlines the default model driven telemetry (MDT) ingestion from IOS XR and IOS XE routers, specifically the following topics:
- IOS-XR Default Sensor Paths and Metrics
- IOS-XE Default Sensor Paths and Metrics
- Customizing Telemetry Collector and Sensor Collector
IOS-XR Default Sensor Paths and Metrics
The default out-of-the-box Telemetry Collector solution ingests the following service assurance metrics from IOS-XR routers:
- Y.1731 (Layer 2) or IPSLA (Layer 3) performance test metrics
- Policy and Interface bandwidth utilization metrics
- Router environment CPU/Memory utilization metrics
The following table explains the object types that appear in Provider Connectivity Assurance, the sensor path that is the source of the telemetry data, and the specific metrics that are ingested.

Customizing Telemetry Collector and Sensor Collector
What to do if you require different metrics from your IOS XE or IOS XR router, or a different data source
If your use case requires MDT telemetry data not included in the service assurance default package with the object types listed above, please contact Sales for a quote on customizing the Telemetry Collector and Sensor Collector for your needs.
