What are networks? Part 2: Network devices and why we need to monitor them

In an era dominated by GenAI technologies, the critical role of robust network infrastructure—the backbone of AI's expansive capabilities—often remains in the shadows. At the heart of this infrastructure lies an intricate array of network devices, including routers, switches, modems, firewalls, wireless access points, etc. These devices, each serving a distinct yet interconnected role, collectively ensure the seamless transmission of data across the network.

Subnets. What is a subnet? How does it work?

Subnetting is the process of dividing a network into several smaller, independent subnets. Each subnet is a portion of the core network that follows a specific logic. We know the definition of the use of subnets in local networks that we could use in our company, y, since the benefits of using subnetting are several.

Kentik Bytes - Identifying Idle Cloud Resources

Phil Gervasi introduces a method for identifying idle resources in AWS using the Kentik platform. By selecting dimensions such as Logging Status, Observing VPC ID, and Observing Region, users can filter the data to determine if a resource is actually doing anything from a network perspective. “No Data” messages indicate resources with no network activity, and a more specific filter can be created based on this message to isolate idle resources. By adjusting the time frame and observing bits per second, users can determine how long resources have been idle.

Kentik Bytes - Cloud Network Performance Metrics

Phil Gervasi introduces a quick and easy way to see network performance metrics among multiple cloud instances. Synthetic tests can be deployed in multiple public clouds to test for loss, latency, and jitter among public cloud instances, such as between AWS and Azure. Phil demonstrates the ability to adjust the time range and shows inbound and outbound traffic, average latency, packet loss, and jitter. A spike in any of these metrics would trigger an alert tied to the ticketing system. He also shows the ability to click into the path view between cloud instances to see a hop-by-hop breakdown.

What is Network Topology? Definition and Overview of Types

Imagine trying to navigate a new city without a map—you wouldn’t know where to go, how to get there, or what obstacles might be in your way. As a network administrator, understanding network topology is just as vital for navigating and maintaining a stable network. Without a detailed knowledge of the pathways of your network infrastructure, troubleshooting and network management become unnecessarily complex.

Enhancing IT Monitoring with DX UIM 23.4 Cumulative Update 2

In the ever-evolving landscape of IT infrastructure, staying ahead of potential issues and ensuring optimal performance is crucial. Broadcom’s DX Unified Infrastructure Management (DX UIM) has been a trusted solution for comprehensive monitoring and management. With the release of DX UIM 23.4 Cumulative Update 2, users can expect a host of new features and improvements designed to enhance their monitoring capabilities.

Capitalizing on the Potential of Automation in Network Operations: Why Integration is Key

In many organizations, network teams are experiencing a significant skills shortage. The network operations center (NOC) requires expertise in various emerging technologies, which makes it increasingly challenging to find qualified candidates with the right skills. A recent survey revealed that in 2022, only 26% of companies found it somewhat to very difficult to hire networking professionals. By 2024, this figure had risen to 41%.

What Are Monitoring Agents & How to Deploy & Configure Them | Obkio NPM Onboarding Series

Welcome! In this video, we’re discussing Network Monitoring Agents in Obkio’s Network Performance Monitoring App. Monitoring agents (software, hardware, virtual appliance) are be deployed to monitor network performance in all network locations. This video will also teach you how to create new Monitoring Agents or to modify or delete Agents you already have in your account.

What is Application Performance Monitoring (APM) & How It Works | Obkio NPM Onboarding Series

Welcome to Obkio’s App! In this video, we’ll be exploring the “Application Performance” tab within the app. You can use Application Performance Monitoring (APM) to monitor web and application performance, and more specifically, to test any website or web application from an HTTP or HTTPS point of view. APM helps you understand if network issues are coming from your local network or not.

What is High Packet Loss & How to Fix It

Believe it or not, seamless and efficient data transmission is super important for both businesses and individual users and impacts a variety of different applications and services. However, one of the common issues that can disrupt this flow is packet loss, which can lead to a variety of network performance problems. High packet loss is particularly concerning since it can severely impact the quality of VoIP calls, video conferencing, online gaming, and even basic web browsing.
