Worked on enhancing IP address management observability in the DataDog/cilium repository by implementing a CIDR capacity label for the IPAM capacity metric. This feature enables tracking of CIDR usage across clusters, supporting more effective capacity planning and risk mitigation for IP address exhaustion. The technical approach involved targeted instrumentation within the Cilium agent, using Go for backend development and metrics monitoring. The contribution consisted of a single, well-scoped commit that adhered to project standards and improved cluster telemetry by surfacing CIDR-level metrics. This work deepened cross-cluster visibility and reliability, addressing operational needs for scalable network resource management.
