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

"BPI: It allows defining peripherals to map business criticality for efficient monitoring, as required."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"It's an essential part of our infrastructure, and we'll keep using it."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"Nagios XI is easy to install, which sets it apart from other open-source solutions I've tried."
"Nagios XI allows my customer to monitor literally thousands of network and computing endpoints (both hardware and software) in real time, including custom derived SNMP polling and traps."
"Nagios is great for verify quality and quantity in a datacenter."
"The dashboard allows you to see what's going on in the overall system."
"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."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"The solution has good dashboards and graphics."
"The solution is so lightweight that with only 4GB of ram, it allows keeping track of up to two hundred agents from a single console."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"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."
 

Cons

"Its simple deployment but complexity comes once you have to import more plugins."
"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."
"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."
"As it is open-source, it is not user-friendly. Open-source software is usually not user-friendly."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"We often need to develop custom plugins to get Nagios to work the way we want it to work because the features we need are not always available in Nagios."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough."
"The GUI could be improved."
"The product lacks APIs for integration with other systems and we have issues with monitoring."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"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."
"A nice feature in the next release would be an automation module to run workflow actions."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"Improvements are needed for server and network discovery, including service-based discovery."
"Third-party integration should be improved for some commonly used products."
"It would be helpful to include the generation of reports for times that the network was out of service."
 

Pricing and Cost Advice

"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."
"As it is not an agentless tool, I think it is expensive."
"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."
"We are using the free version of this solution."
"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."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
