Interfaces, commonly known as ports, are a vital component of any network. Need to connect two pieces of equipment? It could be as easy as plugging in cables—but then you’re using out of the box configurations that don’t follow best practices and are inherently insecure.

ManageEngine has added another gem to its crown, winning the Future Network Awards’ “Network Management and Monitor Vendor of the Year” award for the third time.

kube-proxy is a key component of any Kubernetes deployment. Its role is to load-balance traffic that is destined for services (via cluster IPs and node ports) to the correct backend pods. Kube-proxy can run in one of three modes, each implemented with different data plane technologies: userspace, iptables, or IPVS. The userspace mode is very old, slow, and definitely not recommended! But how should you weigh up whether to go with iptables or IPVS mode?

A common sentiment among our prospects after they see our demo for the first time is: “That’s it? It can’t be that simple!”. The truth is – yes it can be, and it should be. ML and AI should make IT Ops simpler, and a big part of that is usability. If your ML & AI powered IT Ops tools take months to set up and weeks to learn, and then don’t provide a substantially improved user experience, you’re obviously using the wrong tools.

One of the most frustrating service calls you’ll receive is from a client experiencing a network performance issue. The issue could be caused by any number of different things and typically would require you jumping into your car and driving to the client site. The hours drag on while you manually trace wires and test ports to troubleshoot the issue. The longer it takes you to figure it out, the longer you’re interrupting your client’s business.

I’ve just finished getting through security at O’Hare—what an adventure! There were crowds at the check-in, a long security line (luckily I had TSA pre-check), and what seemed like 500 gates I had to pass to get to my gate at the far end of the terminal. We all understand why there are security checkpoints at the airport. They ensure that only those people who belong at the gate are at the gate, and also that there are no malicious actors on airplanes. But why are there so many gates?

Network monitoring at scale is an age-old problem in IT. In this post, I’ll discuss a brief history of network monitoring tools — including the pain points of legacy technology when it came to monitoring thousands of devices — and share my modern-day solution using Sensu Go and Ansible.

When we started working on our data platform to measure the performance of DNS and CDN providers we knew that we had a lot of valuable data. The challenge was to take full advantage of that data and allow easy integration and detailed analysis. To achieve this, we built a robust API which provides access to our full feature stack.
