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."
"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"Since this is an open source technology, if we are capable of writing the plugins in any scripting language, this product allows us to monitor anything we want."
"We love Nagios XI due to the fact that JPS Web is very useful."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"Nagios is stable and it's easy to use the monitoring software, which is why we chose this product."
"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."
"The solution has a lot of plugins and scripts integrated with it."
 

Cons

"They can improve the functionality that provides some numbers related to the behavior of the metrics."
"They need more documentation for the plugins."
"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."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"The interface could be more user-friendly."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"Technical support is an area that needs improvement. It is not available 24/7."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
 

Pricing and Cost Advice

Information not available
"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."
"As it is not an agentless tool, I think it is expensive."
"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 XI is an expensive solution."
"For our country in North Africa, it's expensive and we could purchase another solution for that price. But it's a reasonable price if we're speaking in international terms."
"The pricing is high with separate licensing for the product and support."
"We are using the free version of this solution."
