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.

Provides a stable solution but would improve by developing an all-in-one-solution
The advice I would give to anyone looking at implementing Netreo into their organization would be to do your market research and evaluate the product, do not just choose it because someone recommends it to you. Overall, from my perspective, I would rate the solution a seven out of ten.

Quotes from Members

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

Pros

"I can monitor a phone on a desk to very big servers of any company."
"The integration with the alerting software, automated maintenance windows, and the ability to set up templates and groups of checks, as well as customize the checks themselves, are very valuable features."
"The solution has a lot of plugins and scripts integrated with it."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"Nagios XI is a simple monitoring tool with performance management and everything a standard monitoring tool provides."
"The technical support is good."
"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."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"The technical support team at Netreo is pretty good."
 

Cons

"Nagios XI isn't really good for scaling, in my experience."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"The product could be optimized to improve the administrative user experience via the Nagios Core Configuration (NCC) GUI module."
"The user interface needs improvement. Many tools have poor user interfaces, making them hard to manage and navigate."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"I would like to be able to extend it to all of our data centers, whether they are in the cloud or not. It would be helpful if I could connect everywhere."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"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 scalability of Netreo is lacking."
 

Pricing and Cost Advice

"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The licensing fees for this solution are approximately $3,000 USD per year."
"As it is not an agentless tool, I think it is expensive."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Licensing costs are reasonable."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The pricing is high with separate licensing for the product and support."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
