Simplifying Multi-cloud Visibility

June 13, 2024

Multi-cloud visibility is a challenge for most IT teams. It requires diverse telemetry and robust network observability to see your application traffic over networks you own, and networks you don’t. Kentik unifies telemetry from multiple cloud providers and the public internet into one place to give IT teams the ability to monitor and troubleshoot application performance across AWS, Azure, Google, and Oracle clouds, along with the public internet, for real-time and historical data analysis.

The Importance of Hybrid Cloud Visibility

May 21, 2024

Hybrid cloud environments, combining on-premises resources and public cloud, are essential for competitive, agile, and scalable modern networks. However, they bring the challenge of observability, requiring a comprehensive monitoring solution to understand network traffic across different platforms. Kentik provides a unified platform that offers end-to-end visibility, crucial for maintaining high-performing and reliable hybrid cloud infrastructures.

Transforming Human Interaction with Data Using Large Language Models and Generative AI

March 27, 2024

AI has been on a decades-long journey to revolutionize technology by emulating human intelligence in computers. Recently, AI has extended its influence to areas of practical use with natural language processing and large language models. Today, LLMs enable a natural, simplified, and enhanced way for people to interact with data, the lifeblood of our modern world. In this extensive post, learn the history of LLMs, how they operate, and how they facilitate interaction with information.

How Hard Is It to Migrate to Streaming Telemetry?

February 29, 2024

Streaming telemetry is the future of network monitoring. Kentik NMS is a modern network observability solution that supports streaming telemetry as a primary monitoring mechanism, but it also works for engineers running SNMP on legacy devices they just can’t get rid of. This hybrid approach is necessary for network engineers managing networks in the real world, and it makes it easy to migrate from SNMP to a modern monitoring strategy built on streaming telemetry.

The Benefits and Drawbacks of SNMP and Streaming Telemetry

January 10, 2024

Is SNMP on life support, or is it as relevant today as ever? The answer is more complicated than a simple yes or no. SNMP is reliable, customizable, and very widely supported. However, SNMP has some serious limitations, especially for modern network monitoring — limitations that streaming telemetry solves. In this post, learn about the advantages and drawbacks of SNMP and streaming telemetry and why they should both be a part of a network visibility strategy.

The Power of Paris Traceroute for Modern Load-Balanced Networks

December 19, 2023

Modern networking relies on the public internet, which heavily uses flow-based load balancing to optimize network traffic. However, the most common network tracing tool known to engineers, traceroute, can’t accurately map load-balanced topologies. Paris traceroute was developed to solve the problem of inferring a load-balanced topology, especially over the public internet, and help engineers troubleshoot network activity over complex networks we don’t own or manage.

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.
