📝 Walkthrough

Walkthrough

The pull request adds informational logging to the telemetry handling pipeline in services/hardware-service/handlers.go. When telemetry is received via MQTT, a log records the sensor ID and topic. When publishing succeeds to RabbitMQ or Service Bus, success logs are emitted for each event.

Changes

Telemetry Observability

Layer / File(s)	Summary
MQTT Receipt Logging services/hardware-service/handlers.go	handleTelemetry logs [INFO] mqtt_telemetry_hit with sensor ID, MQTT topic, and reading count after ensuring timestamp is set.
Publication Success Logging services/hardware-service/handlers.go	publishTelemetryToRabbitMQ adds success logs (published_to_rmq / published_to_sb) when RabbitMQ or Service Bus publication succeeds, while preserving existing error/warning logs.

Poem

🐰 The logs now sing with every hop,
Telemetry flows, we watch the plot,
From MQTT hops to buses bright,
Each message seen, from dawn to night! 📡✨
