Overview

OpManager Nexus simplifies telemetry adoption with built-in gNMI monitoring for modern enterprise networks. Reduce dependency on frequent polling with secure telemetry-based data collection and gain deeper visibility into dynamic network environments. Monitor proactively without adding complexity or increasing device load.

Get started

Go beyond standard metrics with flexible gNMI telemetry

Traditional monitoring is limited to predefined metrics. OpManager Nexus's gNMI monitoring provides greater flexibility by enabling teams to:

  • Subscribe to custom telemetry paths based on your operational priorities
  • Leverage YANG models to access granular, device-specific performance data
  • Adapt to new telemetry metrics introduced by modern network devices.

Deploy gNMI monitoring faster with simplified setup

gNMI adoption can be complex due to certificates, authentication, and configuration requirements. OpManager Nexus simplifies deployment by helping teams:

  • Onboard telemetry-enabled devices quickly with minimal manual effort
  • Manage certificate trust and authentication through built-in workflows
  • Standardize telemetry configurations across devices for consistent monitoring.

Scale network monitoring without increasing device load

Frequent polling can increase overhead and impact scalability in growing networks. OpManager Nexus’s telemetry-driven approach helps you:

  • Reduce device overhead by replacing frequent polling with efficient telemetry streams.
  • Handle high-frequency, high-volume network data without performance degradation
  • Maintain consistent monitoring across distributed and high-density environments

Optimize gNMI communication for security and performance

Every network environment comes with its own mix of security requirements and operational constraints. OpManager's gNMI monitoring tool supports multiple communication approaches so you can balance ease of deployment with the level of security your environment demands.

Communication Mode When it makes sense What you gain
Plain text Best suited for lab environments, proof-of-concept setups, or isolated networks. Typically not used in production environments due to lack of encryption and authentication. Enables quick telemetry setup with minimal configuration effort for testing and validation.
TLS Recommended for most production environments requiring secure communication. Provides encrypted data transmission and device authentication with minimal complexity.
Mutual TLS (mTLS) Ideal for high-security or compliance-driven environments. Ensures two-way authentication and strong identity verification for maximum security.

FAQ

What is a gNMI monitoring tool?

A gNMI monitoring tool uses the gRPC Network Management Interface (gNMI) to collect streaming telemetry data from network devices in real time. Unlike traditional polling-based tools, it continuously receives performance data, enabling faster detection of anomalies and improved network visibility.

How is gNMI different from SNMP?

gNMI uses a streaming telemetry model to deliver continuous, real-time data, whereas SNMP relies on periodic polling. This makes gNMI better suited for detecting short-lived issues, reducing latency in monitoring, and improving overall network performance visibility.

When should you use a gNMI monitoring tool?

A gNMI monitoring tool is ideal when:

  • You need real-time visibility into network performance
  • Your environment is large, dynamic, or latency-sensitive.
  • Traditional SNMP monitoring is not fast or detailed enough
  • You want to reduce MTTR and move toward proactive network operations
Is gNMI monitoring secure?

Yes. gNMI supports secure communication using TLS and mutual TLS (mTLS), ensuring encrypted data transfer and device authentication. Most production environments use these secure modes to protect telemetry data.

Does gNMI replace SNMP completely?

Not necessarily. Many organizations use both together: SNMP for basic monitoring and gNMI for high-frequency, real-time telemetry. Over time, gNMI adoption increases as networks demand more granular visibility.
