Nutanix is a cloud OS for Hyperconverged Infrastructure (HCI). It allows you to control from one place your entire IT infrastructure, with a simple interface and/or on smartphones. Nutanix is usually used as a private cloud infrastructure, where the whole stack - processing, data, virtualization, and network resources - is integrated into Nutanix. Since you are putting all your eggs in one

Virtualization is ubiquitous in the IT world. However, with the ever-increasing complexity, we are faced with the fact that our old tools are insufficient nowadays. That is why we need to accustom ourselves to diverse types of NetFlow configuration. In this post, we will examine the case of Hyper-V, a hypervisor developed by Microsoft.

There are two types of Hyper-V

Since Ubuntu 16.04 is approaching its end-of-life (you can, of course, extend it with ESM though that's another story), there is a need to keep your system up-to-date. Unlike CentOS and Red Hat, which don't support in-place upgrades, Ubuntu (and Debian) support upgrading to the new LTS on-the-go.

Procedure

Before we start the upgrade procedure on the NetVizura server, we need

Usually, our customers configure NetFlow export directly on their devices (routers, switches, firewalls, etc). But in case the company policy (especially in Asian countries) prevents enabling export on devices, or if devices are not capable of exporting NetFlow data, we need to implement a NetFlow probe. There are paid probe software options available, however, we will focus on an open-source

NetVizura is a complex software composed of a few databases, Tomcat, and a lot of code, supported on Windows and numerous Linux distributions for AMD64 architecture. With the advent of 8GB RAM RPI 4, there have been numerous projects using this version in its implementation. Maybe the most famous would be ESXi on ARM with project Monterrey (we internally dominantly use Proxmox, while Xen and
