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.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The machine learning feature is valuable."
"The Centerity gives us exactly what we need from performance system monitoring."
"Centerity is much more than a monitoring tool — it’s a unified, end-to-end, enterprise-class and multi-tenanted AIOps Platform that is purpose-built to help MSPs and data-centers deliver the highest levels of up-time and performance."
"You can save a lot of time using Nagios monitoring because otherwise you need to check all of your services or system one by one."
"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The solution has a lot of plugins and scripts integrated with it."
"It's an essential part of our infrastructure, and we'll keep using it."
"It has a wide variety of plugins in existence, but when there's no plugin available it is quite simple to integrate one's own programs and scripts."
 

Cons

"They can improve the functionality that provides some numbers related to the behavior of the metrics."
"The GUI must be improved. Graphs must be changed including high level maps"
"One of the major improvements should be it implementation as a SaaS"
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"The product's stability could be even better."
"Nagios XI can improve its GUI for users with a new look."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"It's in need of more standard plug-ins."
"I would like to see support for notification via SMS."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
