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 XI is a simple monitoring tool with performance management."
"I really found Nagios a perfect fit for us and a good product to work with."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it."
"They have very accurate and fast support."
"Nagios XI is a simple monitoring tool with performance management and everything a standard monitoring tool provides."
"I can monitor a software made in-house to software of bigger companies."
"The alerting system is very effective."
"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."
"We are able to control our business with this all-in-one monitoring tool."
"Stability is where they shine. It has been super stable. We have high-end monitoring for our data centers. We monitor all kinds of metrics in our two data centers. We monitor maybe over 2,500 checks, and the product that has been successful and always alerting us is Pandora."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"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."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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 solution has good dashboards and graphics."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
 

Cons

"I would like to see support for notification via SMS."
"The PNP4Nagios plugin not working easily with XI is an issue for me, because some open source monitoring plugins do not work out of the box. But in the end, you learn to live with it."
"There's room for improvement in the visibility, and in the ability to extract information. Stuff like this should be more simple."
"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"The interface could be more user-friendly."
"While the UI is functional, I have always thought there was room for improvement here."
"Technical support is an area that needs improvement. It is not available 24/7."
"The product does not have SAP monitoring."
"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."
"An update to the Android app would be appreciated."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"Pandora could deliver better analytics out of the box."
"Third-party integration should be improved for some commonly used products."
"In its versions for Linux, in the beginning, it can be somewhat complicated to configure and implement."
"This solution requires proper training to get 100% out of it."
"The price for Pandora FMS is expensive."
 

Pricing and Cost Advice

"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"The pricing is high with separate licensing for the product and support."
"Nagios XI is open source."
"Nagios XI is an expensive solution."
"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 Core does not have any payment, but Nagios XI requires payment for the license."
"Licensing costs are reasonable."
"You have to pay for the number of agents and models that you are monitoring. I would rate the cost at three with one being the most expensive and five being the cheapest."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
"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."
"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 Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
