NIx CN Probes
Enjoy a single, unified observability plane across your entire O-RAN and 5G Core stack
The observability foundation for cloud native 5G networks
NIx CN Probes provide the trusted data foundation that intelligent and autonomous network operations demand. They are what modern 5G networks – disaggregated, virtualised and cloud-native across O-RAN and 5G Core – need in order to remove blind spots typical of traditional hardware probes and equip the NetOps teams with comprehensive, non-siloed and on-time data.
Core NIx CN Probes capabilities
NIx CN Probes are lightweight eBPF probes deployed as Kubernetes daemonsets across every node in your O-RAN and 5G Core infrastructure. They capture a telemetry stream far richer than any hardware probe or agent-based solution. Running inside the Linux kernel, they capture every packet, every system call, every interface interaction — across O-RU, O-DU, O-CU, RIC, AMF, SMF, UPF, and every interface in between — in real time, at wire speed. NIx CN Probes provide:

What NIx CN Probes see
All telemetry provided by the NIx CN Probes is correlated by flow, session and UE, giving NetOps the ability to trace any fault from the radio interface all the way to the internet breakout in a single query.
NIx platform foundation
NIx CN Probes is a standalone product delivering immediate observability and operational value. Its telemetry output feeds contextually into NIx CEM and NIx Agents, creating a unified, AI-ready data layer across the NIx Platform, the type of trusted data foundation that intelligent and autonomous network operations demand.

Why use NIx CN Probes
Automated, end-to-end carrelation replaces manual, siloed investigation. NetOps teams get to root cause faster across both RAN and Core, dramatically reducing MTTR without adding headcount.
Deploy as a Kubernetes daemonset. No hardware to procure, no fixed probe points to plan around. Coverage scales automatically as new Network Functions are deployed to the cluster.
Any UE session, any interface, any time. Trace a call quality issue from the
O-RU all the way to the internet breakout in a single correlated query, without switching tools or stitching data manually.
eBPF runs inside the Linux kernel. No agents to install inside NFs, no NF source code to modify. Instrumentation is completely transparent to the Network Functions being observed.
Pre-correlated telemetry by flow, session and UE feeds directly into NIx Agents, providing the trusted, high-fidelity data foundation that AI-driven autonomous operations demand to act confidently.
Deployable across any O-Cloud environment and any NF vendor. Compliant with O-RAN Alliance specifications and designed for open, disaggregated architectures.
