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.

The open architecture is easy to extend and enhance
Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas. They could improve their management console's ability to monitor large environments could be improved. For example, SNMP management is only partially integrated into the management console.

Quotes from Members

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

Pros

"Nagios has good scalability."
"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."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it."
"The solution has a lot of plugins and scripts integrated with it."
"If you are a mid-sied company with an eye on expansion, this solution is very good."
"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 most useful aspect of this solution is the ability to customize it for the client agent."
"It allows me to quickly see the status of all of my printers, switches, computers, and virtual machines to determine if any system has fallen."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
"Thanks to Pandora FMS, we've been able to adapt to every new monitoring challenge over the past seven years."
"The network monitoring and configuration within this solution is very good."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"Each of these points I think represents the keys as to why this software works in my jewelry stores, as it gives me greater control over all of the devices, the best performance, and I can interpret the data easily and much faster, with excellent results."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
 

Cons

"I feel that the maturity and user interface needs to be improved."
"WebUI should be improved (visual aspect) and should incorporate non-relational databases."
"For some, it may be difficult to deploy."
"As it is open-source, it is not user-friendly. Open-source software is usually not user-friendly."
"I would like to see support for notification via SMS."
"Its simple deployment but complexity comes once you have to import more plugins."
"The reporting part should be made simpler. While we can obtain all the reports we need, we always have to create work-arounds to get them."
"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."
"Pandora could deliver better analytics out of the box. You can work around these limitations with the help of other tools like Grafana. The shortcomings are mostly on the graphical side. The built-in report generators are a bit limited in some areas."
"Improvements are needed for server and network discovery, including service-based discovery."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."
"We would like to see improvement in the mainframe integration that this solution is capable of."
 

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."
"Licensing costs are reasonable."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The licensing fees for this solution are approximately $3,000 USD per year."
"The pricing is high with separate licensing for the product and support."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"My rule of thumb would be that if you need more than thirty agents, and you lack an automation tool such as Chef or Puppet, you will save a lot of time and money going to the Enterprise edition."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
