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.

Pros

"Nagios XI is a simple monitoring tool with performance management and everything a standard monitoring tool provides."
"Nagios is great for verify quality and quantity in a datacenter."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements, it is flexible and easy to integrate with our systems, and you can customize the solution by adding additional features using code."

"It's great for monitoring IT services infrastructure."
"The technical support team at Netreo is pretty good."
 

Cons

"The pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"I think that the community needs to concentrate development to get a standard GUI (Adagios is a side project) and gives the user a better notification system."
"I would like to see support for notification via SMS."
"The important separation between Interface and Core to maintain historical plugins and methods generate complexity that makes Nagios unusable for repeat work."
"However, it is a bit complex and difficult for a first-time user."
"It's in need of more standard plug-ins."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"The installation and monitoring need improvement."
"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."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Licensing costs are reasonable."
"This solution is very expensive, at approximately $5,000 USD when I purchased it, which is why I haven't upgraded my version in several years."
"The pricing is high with separate licensing for the product and support."
"As it is not an agentless tool, I think it is expensive."
"For the cost of the commercial product and support, and taking into account the open source characteristics of it, I believe it is difficult to a better value."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
