Telemetry

Definition

Telemetry refers to the automated process of collecting and transmitting data from remote or inaccessible sources to a receiving system for monitoring and analysis. This data collection enables real-time insights into network performance and helps in making informed decisions for management and optimization. In networking, telemetry provides critical visibility into the health of the system, enhancing control plane functionality and informing network monitoring practices.
