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.

Offers some features but needs better customization and analysis tools
There are solutions that can perform better, but due to pricing for our corporate implementation, we had to stay with this solution. It accomplishes the necessary tasks, but there is room for improvement. The features are not as customizable as we would prefer, but they are workable. If configured properly, you can perform a drill-down analysis. However, I have not used this feature much for our infrastructure on the network side.

Quotes from Members

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

Pros

"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"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."
"The installation is no problem. I've installed Nagios several times."
"Nagios is the best monitoring tool that I have ever worked on."
"The alerting system is very effective."
"Though I downplayed the administrative NCC GUI, this is by far the strongest aspect of the Nagios XI product."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"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."
"You can create an attractive dashboard and create a hierarchy."
"In real-time, we know when there's an issue on our network and it helps us to be proactive to solve the situation."
"In terms of general network monitoring features, I find SolarWinds Network Device Monitor very flexible and comfortable to use. The software itself is extremely useful when it comes to monitoring how our data moves between different networks and environments."
"The alerts we are getting when we start losing connection access have been helpful."
"Link monitoring is the most valuable feature of this solution."
"The most valuable feature of SolarWinds Network Device Monitor is it shows you the utilization of devices to allow you to take proactive action before something goes down or reaches the saturation point. You can take proactive action to fix the problem before it occurs."
"Overall, I rate SolarWinds Network Device Monitor ten out of ten."
"The most valuable features of SolarWinds Network Device Monitor are the reports. We are configuring the reports, and the first reports are only about the devices. We are configuring the thresholds in order to monitor all the devices."
 

Cons

"There are stability issues if you have a large number of hosts and services."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"There's no convenient way to manage notes as the only way is to manage them through the database."
"The GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"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."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"We're still experiencing stability issues with regards to collecting performance graphs."
"Nagios XI can improve its GUI for users with a new look."
"The initial setup is a bit complex. It's not for anyone who is a beginner to work in the products to do it."
"The security could always be improved."
"SolarWinds Network Device Monitor could improve by being more user-friendly. The network has so many features which make it difficult to find how to configure how to use it. It is not simple to customize."
"If everything were in the package so that everything was ready to go out of the box, that would be ideal."
"In terms of price, it could be less expensive."
"When an organization's network grows, the complexity of the dashboard becomes an area of concern where improvements are required."
"SolarWinds pricing is on the higher side, and in India, every customer is cautious about commercial aspects."
"It should provide user-friendly page"
 

Pricing and Cost Advice

"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is high with separate licensing for the product and support."
"We are using the free version of this solution."
"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"As it is not an agentless tool, I think it is expensive."
"SolarWinds Network Device Monitor is not an expensive solution."
"The enterprise license is good for the SolarWinds Network Device Monitor. However, it is expensive, they should reduce their price."
"Thankfully, it doesn't take a lot of manpower to install and deploy."

"I rate the product's price as three to three and a half or on a scale of one to ten, where one means low price, and ten means high price."
"Well, we had a perpetual license and the renewal was $20 to $25,000."
