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 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 Script Module in Nagios is really easy to use and is really cost efficient."
"Overall, it's a powerful system."
"An excellent solution that is easy and intuitive to implement."
"The solution is pretty stable."
"The solution has a lot of plugins and scripts integrated with it."
"It has a wide variety of plugins in existence, but when there's no plugin available it is quite simple to integrate one's own programs and scripts."
"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. It's also scalable enough to support large environments."
"Pandora FMS is a powerful monitoring system that has enabled us to identify and resolve IT infrastructure problems before they affect critical business processes."
"This solution has screens that are easy to understand and provide a wealth of information."
"We are able to control our business with this all-in-one monitoring tool."
"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."
"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."
"It provides us with proactive monitoring and is very easy to configure and maintain."
 

Cons

"Adding new servers and passive checks (which require setting up agents and NRDS) on servers are a little difficult to do properly when employees don't understand the process."
"If you are monitoring network devices, often it's not scaled for large corporations. Definitely, a minus in that area."
"The Configuration Wizard needs improvement, because not all vendors are present."
"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 GUI could be improved. It's a bit too basic, and maybe having a GraphQL interface would resolve this."
"The scalability of Nagios XI is scalable. However, it is not easy to do."
"I would like to see support for notification via SMS."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"Pandora could deliver better analytics out of the box."
"When it comes to the definition of local Software Agents for the first time in the open-source version, it can become very tedious."
"An update to the Android app would be appreciated."
"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."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"In the future, we may have double the number of devices, and we do not want to have any issues with performance in the data display."
 

Pricing and Cost Advice

"Licensing costs are reasonable."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"It is good to contact experts for advice about what is the best solution for your specific infrastructure and enterprise."
"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."
"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios Core does not have any payment, but Nagios XI requires payment for the license."
"The pricing is high with separate licensing for the product and support."
"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."
"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."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
