Sanskar Jaiswal developed observability instrumentation for the Kong/kong repository, focusing on improving reliability through enhanced monitoring of data plane connectivity. He introduced a Prometheus gauge metric, control_plane_connected, which reports the health of the connection between the Kong data plane and control plane, enabling real-time detection and alerting of connectivity issues. The implementation involved updating the connection logic in Go to set the metric’s value and exposing it through the existing Prometheus endpoint. Sanskar’s work demonstrated depth in system design, monitoring, and networking, providing a robust solution for tracking connectivity health without addressing bug fixes during this period.
