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.

Has improved traffic visibility and simplified dashboard use, but could benefit from better integration with other tools

Quotes from Members

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

Pros

"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."
"It is an open-source platform with valuable features for performance and stability."
"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."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"The solution is pretty stable."
"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"I can monitor a software made in-house to software of bigger companies."
"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"NETSCOUT nGeniusPULSE has an easier dashboard to manipulate compared to SolarWinds."
"We have seen a measurable decrease in mean time to know and mean time to repair, and because the tool allows us to get to things a lot quicker and see things a lot quicker, we have actually reduced those times and it has definitely helped with our network uptime, with an improvement in uptime of at least 50 percent."
"I like the single pane of glass view. I like being able to go to one place instead of having to hunt around for everything."
"I like the single pane of glass view because it presents everything in one window, obviously. You can see it all. With a quick glance, you get a pretty good snapshot of what's going on in a particular situation."
"The most valuable features of this solution are monitoring and maintaining traffic queuing, as well as seeing who is using the bandwidth."
"nGenius provides us with increased visibility during IT deployments."
"The most valuable features of this solution are monitoring and maintaining traffic queuing, as well as seeing who is using the bandwidth."
"The solution's technical support team consists of good engineers and technicians."
 

Cons

"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."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"I would like to see support for notification via SMS."
"We're still experiencing stability issues with regards to collecting performance graphs."
"It can be quite difficult to know which drivers and agents to use when setting up."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"They require a lot of manual effort as traffic flows, networks, and formal times change."
"Usability is the area with the biggest room for improvement. We've found that with NETSCOUT, while it's a fantastic product, the usability is a major factor because there are just way too many clicks."
"They require a lot of manual effort as traffic flows, networks, and formal times change."
"Usability is the area with the biggest room for improvement. We've found that with NETSCOUT, while it's a fantastic product, the usability is a major factor because there are just way too many clicks. It's obvious, from our experience, that the people who are developing the product aren't using it."
"In terms of additional features, I would like to see better event notification. Right now, we put in an email address to receive an alert and it receives every event and every alert that comes out."
"Before an attack starts, seeing the traffic behavior and activities would be great. The tool should also share alerts since it is an area where the product has certain shortcomings."
"NETSCOUT nGeniusPULSE is not integrated with SolarWinds. They work in different ways."
"In terms of additional features, I would like to see better event notification. Right now, we put in an email address to receive an alert and it receives every event and every alert that comes out. We need something a little more granular."
 

Pricing and Cost Advice

"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 licensing fees for this solution are approximately $3,000 USD per year."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"We are using the free version of this solution."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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 open source."
"The pricing is high with separate licensing for the product and support."
"The tool's price is okay. On a scale of one to ten, I rate it as a five, where one means it is not expensive, and ten means it is the most expensive."
