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 stable."
"For anyone who is interested in using this solution, I would recommend it."
"The features I've found the most useful are the plug-ins, the fact that you can connect almost everything to it."
"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. You can customize the solution by adding additional features using code."
"The solution is pretty stable."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"The dashboard allows you to see what's going on in the overall system."
"The solution's most valuable feature is its simplicity."
"Network monitoring is fun again with Pandora FMS."
"We are consultants and thanks to Pandora can detect a lot of disasters that other companies can't, and we can offer high availability of the system to the client."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"It is easy to create your own custom modules if you just know a little bit of scripting. If you have unique requirements, you can just make your own modules. You can even grab checks from other vendors. There are open-source checks for various things such as SMTP, etc. There is a long list of different ones from Nagios. You can just use them, and within seconds, you get yourself a check that is monitoring whatever you need. It is really flexible. I guess that's why they call it Pandora Flexible Monitoring System (FMS). It is reliable. It does the job, and it alerts. It is also surprisingly feature-rich. Our network guy just recently asked about a particular protocol to monitor the bandwidth on the network, which is not a common protocol. When I looked it up, and I found that they cover it. It is very mature for a not-so-known product."
"The official forum is active enough to answer most of the high-end technical questions that you may have."
"Pandora's architecture is interesting; it's open so you can easily extend and enhance it, it's simpler to customize Pandora compared to other solutions, and it's also scalable enough to support large environments."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"The solution has good dashboards and graphics."
 

Cons

"Reporting items needs more improvement and need to be more flexible based on customer needs."
"Business services monitoring is still really basic."
"Nagios XI isn't really good for scaling, in my experience."
"The tool's AI model needs to be fixed."
"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."
"There's room for improvement in the visibility, and in the ability to extract information."
"The user interface needs improvement."
"Nagios XI can improve its GUI for users with a new look."
"We would like to see improvement in the mainframe integration that this solution is capable of."
"It would be helpful to include the generation of reports for times that the network was out of service."
"Third-party integration should be improved for some commonly used products."
"An update to the Android app would be appreciated."
"Third-party integration should be improved for some commonly used products such as Universal CMDB."
"A nice feature in the next release would be an automation module to run workflow actions."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
 

Pricing and Cost Advice

"The pricing is high with separate licensing for the product and support."
"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."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"We are using the free version of this solution."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"Licensing costs are reasonable."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
