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

"It's great for monitoring IT services infrastructure."
"I can monitor a phone on a desk to very big servers of any company."
"In my view this product is very good value for money when compared with other commercially provided monitoring solutions."
"Nagios XI allows my customer to monitor literally thousands of network and computing endpoints (both hardware and software) in real time, including custom derived SNMP polling and traps."
"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."
"It is an open-source platform with valuable features for performance and stability."
"It is a very stable solution and the best solution for monitoring any IT infrastructure for all companies."
"The most valuable features of Nagios XI are you can customize it based on your use case and requirements, it is flexible and easy to integrate with our systems, and you can customize the solution by adding additional features using code."
"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."
"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."
"The solution's technical support team consists of good engineers and technicians."
"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."
"nGenius provides us with increased visibility during IT deployments."
"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."
 

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."
"The product uses the backend as Perl and could be modified to a more lightweight solution like what's being offered by other vendors."
"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."
"The Configuration Wizard needs improvement, because not all vendors are present."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"It's in need of more standard plug-ins."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"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."
"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."
"They require a lot of manual effort as traffic flows, networks, and formal times change."
"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

"The pricing is high with separate licensing for the product and support."
"Nagios XI is an expensive solution."
"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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 really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
