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

"They have very accurate and fast support."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"Our infrastructure is now under monitoring proactively and we don't have to wait for complaints from the customers or internal operation team to inform regarding any issue with the service."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it. That's very useful."
"The alerting system is very effective."
"I can monitor a software made in-house to software of bigger companies."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"It provides us with proactive monitoring and is very easy to configure and maintain."
"Thanks to this software and to the work of the support team, we have everything under control."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"The network monitoring and configuration within this solution is very good."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"The support from Pandora FMS is legendary."
"Thanks to this software and to the work of the support team, we have everything under control."
"The solution has good dashboards and graphics."
 

Cons

"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"Technical support is an area that needs improvement. It is not available 24/7."
"The Configuration Wizard needs improvement, because not all vendors are present."
"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."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"They need to develop a better integration with a common ticketing system will be great."
"It's in need of more standard plug-ins."
"While this solution works, I think that it can be improved in terms of maintenance, support, and price."
"An update to the Android app would be appreciated."
"An update to the Android app would be appreciated."
"Pandora FMS is relatively new, and the interface with the older version crashes at times."
"Their support is good, but it is just online communication. It would be great to be able to just call someone and talk to them instead of always writing. It works well for me because I am a decent communicator in email, but some people might find it difficult to describe in a written fashion and communicate with them that way. There is a learning curve to the interface, but once you get used to it, it is actually very powerful. They have a lot of options, but people struggle with the interface. They've improved it though, and it is getting better. They need to keep improving the learning curve to help buy-in. I'm the guy that manages it, so I'm comfortable with it. They can refine the upgrade agents to be easier. They can also do more refinement in end-user usability because not everyone is strong technically, and people who aren't strong technically might be averse to the product, even though it has come a long way. It has a complete GUI and everything."
"Pandora could deliver better analytics out of the box."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"Improvements are needed for server and network discovery, including service-based discovery."
 

Pricing and Cost Advice

"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."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"Nagios XI is open source."
"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."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"Licensing costs are reasonable."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
