Model Driven Telemetry (MDT) is a push-based streaming telemetry mechanism that provides real-time, structured data from network devices using YANG data models and protocols such as gRPC, enabling continuous monitoring and analytics. It supports both periodic data collection and event-driven notifications with configurable update policies, allowing network operators to receive precise operational data including interface statistics, routing table changes, and system health metrics. MDT subscriptions eliminate the need for polling-based monitoring by delivering high-frequency, low-latency data streams that can be consumed by network management systems, analytics platforms, and automated monitoring tools.
