Operational monitoring can be like looking down the wrong end of a telescope. There’s no clear picture of the horizon. Everything is blurred, indistinct, and difficult to trace. If you’re relying on traditional, domain-centric monitoring, you’re faced with a similar problem: you can see the performance of individual elements, but you don’t have any visibility into the broader picture.

In one of our preceding blogs, we spoke about Software-Defined Networking (SDN) and the key drivers behind it. Virtualisation is one of the fundamental aspects that characterises SDN, and has influenced the architecture of network switching in the data centre. OVS (Open vSwitch) is a fundamental component of modern and open data centre SDNs, where it aggregates all the virtual machines at the server hypervisor layer.

Forty percent of enterprises say an hourly network outage costs up to $1 million. Evidently, one minor overlook in monitoring the performance and availability of a network can result in costly downtime. This is why firms that heavily rely on network operations should perform dynamic network monitoring to keep their network protected from unexpected downtime.

Last month, the long-awaited film adaptation of Frank Herbert’s sci-fi epic Dune was released in theaters and on HBO Max. Directed by Canadian filmmaker Denis Villeneuve, the movie was a hit at the box office as well as via streaming, leading to another OTT traffic surge.

For organizations growing larger by the day, network management becomes increasingly complex, and scaling to meet this growth can be a major headache. To battle such complexity without a graphic representation of a network is a tiresome task, which is where network diagram software comes in. Network diagram software allows a network admin to portray the network clearly and legibly through detailed graphics.

Last month, we partnered with AWS to put together a webinar on the importance of implementing a comprehensive redundant networking and multi-CDN monitoring strategy. You can replay the event in full here. In this article, we’ll recap the key takeaways covered by the panel of experts who included Leo Vasiliou, Director of Product Marketing at Catchpoint, and Steve Campbell, our Chief Strategy Officer.

Today, we are launching the newest feature of Broadcom’s Enterprise Software Academy: DX Unified Infrastructure Management (DX UIM) resource pages. DX UIM is redefining infrastructure management with full-stack observability, an open architecture, modern admin and operator consoles, and zero-touch configuration.

DX Unified Infrastructure Management (DX UIM) has more than 150 monitoring probes, which enables IT administrators to monitor everything from traditional mainframe servers to modern hybrid clouds running on a wide range of platforms and operating systems. Traditionally, a separate probe has been required to monitor each specific technology. That’s because the interface that retrieved monitoring metrics was either proprietary or technology specific.

Willy Tarreau, the founder of the HAProxy load balancer, 20 years past its initial, open-source release, still guides the project, often submitting code patches and writing long and meticulous replies on the community forum. Over the years, he has been joined by a cast of regular contributors, but also newcomers. This collaboration has kept the project evolving over time. In this interview, Willy describes his views on the success of the project, and how it grew over the years.

The current version of DX APM continues a long history of innovation for APM technology. More than two decades ago, the solution was the pioneer in byte code instrumentation. DX APM is now a next-generation solution for today’s complex and hybrid enterprise environments. Figure 1: Broadcom’s DX APM has evolved from Wily Technology’s invention of byte code instrumentation-based APM, which was introduced in 1998.

Connectivity is more valuable to today’s businesses than ever. Partly, this is because many business-critical operations are happening online. Employees are connecting using collaborative software. Customers are seeking support and placing orders online. At the same time, suppliers and partners are transmitting data online. All their success depends on network capacity and reliability.

One of the positive things that came out of events in 2020 was that many of us started working from home. At first, it was kind of weird. But once we realized that what we needed was available online, it became easier. All we had to do was figure out a few new apps, like Slack, Asana and Google Docs. Then, after a couple of weeks of working from home, many of us started having thoughts like, “I wonder if I could wear shorts and my favorite slippers?

The capacity to scale and process high data traffic by monitoring appliances is a critical requirement for organizations aiming to enhance or improve their security and protection from external threats. Excessive incoming traffic demands high-monitoring capabilities as it overwhelms the monitoring tools and places computational bounds that increase exponentially.

In this article, we will explore why it is imperative to constantly monitor network security metrics, what Aruba Clearpass is, and how it helps us manage network security. Then we will look at what Graphite and Grafana are and how to analyze metrics with their help. Finally, we will learn how MetricFire can make it easier for us to work with Graphite and Grafana.

This blog post is part of our data centre networking series: In the previous blogs, we covered the architecture and main drivers behind software-defined networking. In this one, we discuss the impact of softwarisation on the other important data centre building blocks, culminating in software-defined data centres (SDDC).

Network monitoring tools gather and analyze network data to provide network administrators with information related to the status of network appliances, link saturation, the most active devices, the structure of network traffic or the sources of network problems and traffic anomalies.

It is crucial for network admins to fully understand their network topology. Even basic troubleshooting can be needlessly complicated without a network topology diagram which is vital for building and maintaining a network. A network topology diagram shows how the various components work together; it shows the devices, connections and pathways of a network visually so you can figure out how devices interact and communicate with one another.

In our last blog, we spotlighted the Oceania region and showed you how you can use DNSPerf and PerfOps to compare providers. Today, we’ll be focusing on Africa, the top providers there, and how you can use this data to make better DNS business decisions for your domain. This will give you greater insight into your current or potential provider’s performance. You should have the fastest, highest-quality DNS for regions you cater to most.

The increasing need for mobility has accelerated many organizations’ shift towards wireless networks, commonly known as Wi-Fi networks. The high bit rate and bandwidth offered by wireless networks enable a better networking experience than their wired counterparts. In an ideal network, once you set up your Wi-Fi components, your end users should be able to connect and access your network with ease.
