Beyond polling: Why enterprises are exploring network telemetry

Polling has been the go-to approach for network monitoring for years, and it still plays an important role in keeping networks healthy. But as networks become more distributed, application-driven, and data-intensive, simply polling devices more often isn't always the most efficient way to gain deeper operational insights.

That's where network telemetry comes in. With OpManager's gNMI-based network telemetry monitoring, teams can collect continuous operational insights from supported devices, helping them better understand network behavior while keeping monitoring overhead under control.

Why modern networks demand more visibility 

Modern networks power everything from cloud applications and remote work to customer-facing services. As these environments grow, understanding network performance becomes increasingly important.

While traditional polling remains effective for monitoring device health and availability, it only provides visibility at specific points in time. Short-lived performance issues can occur between polling intervals, making them difficult to identify and troubleshoot.

Organizations today need monitoring strategies that help them:

• Maintain visibility across distributed environments

• Monitor growing numbers of devices and services

• Understand changing network conditions more effectively

• Support business growth without increasing monitoring complexity

This growing need for operational awareness is one of the key reasons organizations are exploring network telemetry.

Network telemetry in action

Consider a retail organization with hundreds of branch locations. A temporary spike in WAN utilization could impact application performance for several minutes before disappearing. By the next polling cycle, the issue may no longer be visible. Having additional operational insights can make troubleshooting and capacity planning significantly easier.

How OpManager's network telemetry monitoring helps 

OpManager's gNMI-based network telemetry monitoring complements traditional network monitoring by collecting continuous operational data from supported devices. Instead of relying exclusively on periodic polling, teams gain additional context that helps them better understand network behavior and performance trends.

Gain granular performance insights with less overhead 

Getting more visibility shouldn't mean generating more monitoring traffic.

OpManager helps organizations collect detailed operational insights from supported devices, making it easier to understand what's happening across the network while reducing dependence on increasingly frequent polling.

With OpManager, you can:

• Track performance changes with greater detail

• Reduce reliance on frequent polling

• Scale visibility across distributed environments

Enable continuous visibility with streaming telemetry 

Network conditions can change in seconds, not minutes. That's why waiting for the next polling cycle isn't always enough.

With gNMI-based streaming telemetry, OpManager continuously receives operational data from supported devices, helping teams stay informed about changing network conditions and emerging performance concerns.

This helps organizations:

• Monitor dynamic environments more effectively

• Identify issues sooner

• Improve visibility across critical infrastructure

Turn telemetry insights into smarter planning decisions 

Telemetry data isn't just useful for day-to-day monitoring. Over time, it can reveal valuable trends that help teams understand how network resources are being used and where future demands may arise.

Instead of reacting to capacity challenges after they affect performance, organizations can make more proactive decisions based on actual usage patterns.

OpManager helps teams:

• Identify utilization trends earlier

• Spot potential capacity constraints proactively

• Make informed infrastructure planning decisions

Polling and telemetry are better together 

It's easy to think of telemetry as a replacement for polling, but that's not how most organizations use it in practice.

Polling remains a reliable way to monitor network health, availability, and overall performance. Telemetry simply adds another layer of operational insight, helping teams better understand what's happening between polling intervals.

Together, they provide a more complete picture of network performance.

Rather than choosing one approach over the other, many organizations are combining both to strengthen their monitoring strategy.

Looking beyond polling with OpManager?

Polling remains an essential part of network monitoring, but modern networks often require more than periodic snapshots to understand performance and operational trends.

By combining traditional monitoring with gNMI-based telemetry, OpManager helps teams gain richer operational insights, reduce monitoring overhead, and make more informed decisions. Network telemetry isn't about replacing polling; it's about helping you see more of what's happening across your network.
