Worked on enhancing telemetry observability in the rdkcentral/telemetry repository by developing Dynamic Telemetry Markers for DataModelTable, enabling per-instance data collection from dynamic multi-instance tables. Leveraged C programming and JSON handling to implement configuration-driven filtering and encoding of telemetry data, allowing for more granular and flexible reporting. Integrated improvements to the T2 agent, ensuring comprehensive data collection across all table instances when dynamic markers are present. Introduced an index parameter to restrict data gathering to specific instances, optimizing telemetry overhead. This work improved data fidelity, troubleshooting efficiency, and configurability within complex telemetry pipelines, demonstrating depth in data modeling and telemetry systems.
