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 is stable and it's easy to use the monitoring software, which is why we chose this product."
"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."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails, and it also allows us to schedule downtime and maintenance."
"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."
"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"It is an open-source platform with valuable features for performance and stability."
"An excellent solution that is easy and intuitive to implement."
"The technical support team at Netreo is pretty good."
 

Cons

"We'd like to see more integration capabilities."
"Nagios XI can improve its GUI for users with a new look."
"The product does not have SAP monitoring."
"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."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"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 reporting structure could be more streamlined."
"The scalability of Netreo is lacking."
 

Pricing and Cost Advice

"We are using the free version of this 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."
"The pricing is high with separate licensing for the product and support."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"As it is not an agentless tool, I think it is expensive."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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 licensing fees for this solution are approximately $3,000 USD per year."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
