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

"The ROI is very good."
"Nagios is an open source monitoring tool for monitoring network services, with easy installation, a user-friendly and configurable interface, and the ability to monitor disk space, CPU utilization, memory usage, host availability, NFS availability and many other things, making it widely used in IT markets."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"Nagios XI simplifies our setup and reduces the time spent configuring monitoring tools."
"Nagios XI is stable."
"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."
"We love Nagios XI due to the fact that JPS Web is very useful."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"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. It's also scalable enough to support large environments."
"The support from Pandora FMS is legendary."
"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."
"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."
"The solution has good dashboards and graphics."
"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 (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
 

Cons

"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."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"The NCC does have issues where it locks up or an admin cannot be sure if the system configuration was exact."
"For some, it may be difficult to deploy."
"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."
"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."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough."
"I would like to see support for notification via SMS."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"I would like for the solution to be faster and have a better tolerance between parallel servers for Pandora and Pest Control."
"I think some improvements to the Android app would be good."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"It would be helpful to include the generation of reports for times that the network was out of service."
"Pandora could deliver better analytics out of the box."
"It would be useful if Pandora FMS included an ISO image (or «software appliance») for each big company that leases virtual private machines (VPS), just like in AWS."
"I find that this software is resource heavy, and demands a lot of processing capacity."
 

Pricing and Cost Advice

"Nagios XI is open source."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"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."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"The licensing fees for this solution are approximately $3,000 USD per year."
"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."
"We are using the free version of this solution."
"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."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"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."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
