Modernizing Network Data Analytics With a Unified Data Repository

May 11, 2023

In this post, learn about what a UDR is, how it benefits machine learning, and what it has to do with networking. Analyzing multiple databases using multiple tools on multiple screens is error-prone, slow, and tedious at best. Yet, that’s exactly how many network operators perform analytics on the telemetry they collect from switches, routers, firewalls, and so on. A unified data repository unifies all of that data in a single database that can be organized, secured, queried, and analyzed better than when working with disparate tools.

Why Your Data-Driven Strategies for Network Reliability Aren’t Working

April 25, 2023

What do network operators want most from all their hard work? The answer is a stable, reliable, performant network that delivers great application experiences to people. In daily network operations, that means deep, extensive, and reliable network observability. In other words, the answer is a data-driven approach to gathering and analyzing a large volume and variety of network telemetry so that engineers have the insight they need to keep things running smoothly.

eBPF Explained: Why it's Important for Observability

April 4, 2023

eBPF is a powerful technical framework to see every interaction between an application and the Linux kernel it relies on. eBPF allows us to get granular visibility into network activity, resource utilization, file access, and much more. It has become a primary method for observability of our applications on premises and in the cloud. In this post, we’ll explore in-depth how eBPF works, its use cases, and how we can use it today specifically for container monitoring.

The evolution of network visibility

April 20, 2022

In the old days, we used a combination of several data types, help desk tickets, and spreadsheets to figure out what was going on with our network. Today, that’s just not good enough. The next evolution of network visibility goes beyond collecting data and presenting it on pretty graphs. Network observability augments the engineer and finds meaning in the huge amount of data we collect today to solve problems faster and ensure service delivery.
