Simplifies setup and requires user interface enhancement
Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried. Typically, setting up a monitoring system on Linux involves cloning files from GitHub, building it, and installing many dependencies, but with Nagios XI, it wasn't like that. Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools.

The setup is straightforward, but t​he satellite service installation file could be separated from the server one.
* The status overview page provides a state of computers monitored and provides quickly what users need to focus on * The satellite service installed on remote computers is an easy way to add clients, plus it's easy to deploy and to configure * The licence is perpetual and not linked to one computer, so it's possible to remove a licence from one computer and use it on another with no extra cost
