• RDK telemetry data is send from every RDK device on a specific interval
• Ability to generate critical matrix using the configured parameters
• Leverages logs, different system status information and snmp commands
• Uses key-value pairs for data upload

RDK telemetry data is sent from every RDK device periodically. During bootup, Xconf sends certain parameters (matrix info which it likes to gather). It sends what parameter and where to reteive it from.

STB sends request to server with version, device details etc. Based on server rules, telemetry agent retrieves the telemetry markers from server.

Server can configure how often it needs telemetry data.
