Most network monitoring tools alert you that a device is down. The best ones help you determine whether the problem is your WAN circuit, your ISP, or your SaaS provider before your users file a ticket. Traditional network monitoring tools were built for static networks. You poll devices, check interface counters, and still can’t explain why users are complaining about latency.

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.

Every layer of the modern network stack moves at cloud speed. If your connectivity doesn't, your entire strategy can stall. Co-authored by Fabio D’Avino This blog includes insights from Fabio D’Avino, a specialist in Network as a Service (NaaS) with more than seven years of experience researching, designing, and building global network services. Fabio’s work explores how organizations can modernize connectivity as cloud, hybrid, and AI-ready infrastructure strategies evolve.

Network admins want all devices with the same role to behave the same way. But in real environments, that consistency rarely lasts. Imagine two core switches in the same data center. They serve the same function and run the same OS version. One handles traffic without issue, while the other drops packets during peak hours. Logs show nothing obvious. Routing looks correct. The team spends hours checking links, hardware, and traffic paths.

In the world of enterprise Agile, we face a persistent paradox: How do we empower individual teams to establish their own unique processes, while ensuring leadership maintains a clear, consistent view of the entire organization’s progress? For a long time, the answer was a compromise.
