INTRODUCTION
Telemetry is a feature used in RDK broadband Gateway devices to extract and upload specific error logs or event logs from the Gateway to the Splunk server. These logs are used to remotely monitor the Gateways in the field.
The logs to be monitored and the frequency of capturing the logs can be configured from the Xconf server, in the form of a marker.
RDK-B Telemetry Architecture

Design consideration:
For the Telemetry feature, there are 2 servers maintained.
Telemetry data flow
Marker
A marker provides the errors or events appearing in the RDK logs. These markers are predefined in the Xconf server. These markers are set based on the events or errors that need to be monitored for any device.
Each marker contains 4 fields:
Marker example

“content”: “System Not Ready !!!! ‘com.cisco.spvtg.ccsp.wifi’ v1 NotRegistered”,
“type”: “CRlog.txt.0”
“frequency”: “0”
}
