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

Cons

"Nagios XI can improve network and hardware monitoring, these parameters should be simplified to allow usage for monitoring. Additionally, if there was automatic reporting it would be helpful."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"The NCC does have issues where it locks up or an admin cannot be sure if the system configuration was exact."
"For some, it may be difficult to deploy."
"Its simple deployment but complexity comes once you have to import more plugins."
"It can be quite difficult to know which drivers and agents to use when setting up."
"The installation can get very difficult depending on what Linux flavour you are using."
