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

"Nagios XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"The ability to set up templates and groups of checks, as well as customize the checks themselves."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"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."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"The technical support team at Netreo is pretty good."
 

Cons

"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."
"From an alerting point of view, some graphics and metrics don't work properly with Nagios XI as they do with Checkmk."
"We'd like to see more integration capabilities."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"Open-source software is usually not user-friendly."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The installation and monitoring need improvement."
"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."
"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."
"Licensing costs are reasonable."
"The pricing is high with separate licensing for the product and support."
"Nagios XI is an expensive solution."
"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."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"We are using the free version of this solution."
"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."

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…
