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
NETSCOUT nGeniusPULSE works very well in our case. We have not experienced any troubles with traffic analysis SolarWinds has a dashboard that is older and not as user-friendly. NETSCOUT nGeniusPULSE has an easier dashboard to manipulate compared to SolarWinds. NETSCOUT nGeniusPULSE is not…

Quotes from Members

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

Pros

"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it."
"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."
"Overall, it's a powerful system."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"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."
"The solution is pretty stable."
"The Script Module in Nagios is really easy to use and is really cost efficient."
"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."
"nGenius provides us with increased visibility during IT deployments."
"The solution's technical support team consists of good engineers and technicians."
"NETSCOUT nGeniusPULSE has an easier dashboard to manipulate compared to SolarWinds."
"The most valuable features of this solution are monitoring and maintaining traffic queuing, as well as seeing who is using the bandwidth."
"The most valuable features of this solution are monitoring and maintaining traffic queuing, as well as seeing who is using the bandwidth."
"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."
 

Cons

"Nagios XI doesn't provide scripting. For example, if we have built up multiple IPX tunnels from a base location to a data center location and want to monitor or trigger an alert if the tunnel goes down, Nagios XI does not automatically send alerts notifying us that the tunnel is down."
"Business services monitoring is still really basic."
"However, it is a bit complex and difficult for a first-time user."
"We're still experiencing stability issues with regards to collecting performance graphs."
"Open-source software is usually not user-friendly."
"The technical support is variable - sometimes I get answers, but most of my tickets go unanswered."
"While the UI is functional, I have always thought there was room for improvement here."
"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."
"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."
"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."
"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."
"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."
"They require a lot of manual effort as traffic flows, networks, and formal times change."
"They require a lot of manual effort as traffic flows, networks, and formal times change."
 

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."
"Nagios XI is open source."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"As it is not an agentless tool, I think it is expensive."
"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."
"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."
