For years, network monitoring has relied on the polling model, asking devices for their status every few minutes. In the age of high-speed enterprise networks, this is no longer enough. Transient congestion, micro-bursts, and rapid BGP flaps often vanish before the next poll, leaving network teams blind to the root causes of performance issues.
ManageEngine has officially addressed this with the latest release of OpManager Nexus, introducing native support for gNMI (gRPC Network Management Interface) and OpenConfig streaming telemetry.
Traditional SNMP-dependent monitoring creates a trade-off: higher collection frequency equals higher infrastructure overhead. Streaming telemetry flips this model. By pushing data from the device to the monitoring platform in real-time, organizations can achieve:
- Sub-second Granularity: Capture events that traditional polling misses entirely.
- Reduced Overhead: Lower CPU and memory strain on network devices compared to heavy polling cycles.
- Operational Efficiency: Aligning monitoring with sustainability goals by reducing redundant data cycles.
One of the biggest challenges for modern network teams is stitching together data from different vendors. OpManager Nexus solves this by using OpenConfig YANG models as a normalization layer. Whether you are running Cisco, Juniper, Arista, Nokia, or Huawei, you get a consistent data structure across your entire multi-vendor estate.
The beauty of this update is that it doesn’t require a new tool. ManageEngine has unified SNMP, NetFlow, and gNMI telemetry into a single platform.
Network teams no longer need to manage a collection of open-source collectors, time-series databases, and fragmented dashboards. Everything is integrated into the existing OpManager Nexus topology, alerting, and reporting workflows. As Vikas Yadav, Senior IT Administrator at WAISL Limited, noted: “We could finally see those short-lived events in real time without bringing in another telemetry tool.”
This is a move toward a more sustainable, high-fidelity future for network observability, giving teams the data they need to act before services are affected.
