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 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 XI helps us monitor the bandwidth of the internet connection, HTTP, DNS, active directory services, and exchange data availability. We have multiple servers to monitor databases, availability of servers, and ping."
"The most valuable feature is the monitoring of processes."
"The most useful aspect of this solution is the ability to customize it for the client agent."
"The solution has a lot of plugins and scripts integrated with it."
"In my experience with Nagios, I've found that the most valuable features are the scalability and extensibility through using scripts."
"The dashboard allows you to see what's going on in the overall system."
"It's a monitoring agent. It's designed to do one thing. Its most valuable feature is its monitoring."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"The most valuable feature is that it is an all-in-one monitoring system."
"Thanks to this software and to the work of the support team, we have everything under control."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"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."
"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."
"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

"I would like a much easier GUI so that I can delete events and logs, which will free up a lot of space."
"It is really difficult to integrate Nagios XI with another system to generate logs and alert our management of failures in security infrastructure."
"The installation can get very difficult depending on what Linux flavour you are using."
"The interface could be more user-friendly."
"The product does not have SAP monitoring."
"The web interface is perfectly fit for purpose but isn't up there with the best modern admin panels."
"I would like to see more customization in the network map because it is a bit tricky to use it."
"Technical support is very good but is very expensive. It is becoming more and more expensive just like the upgrade."
"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 sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"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."
"I think some improvements to the Android app would be good."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"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."
"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."
"We would like the real-time monitoring of an interface to be improved within this solution."
 

Pricing and Cost Advice

"The licensing fees for this solution are approximately $3,000 USD per year."
"Nagios XI is open source."
"The pricing is high with separate licensing for the product and support."
"We are using the free version of this solution."
"Nagios XI is an expensive solution."
"As it is not an agentless tool, I think it is expensive."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
"They are very competitive on the pricing side. That's one reason why my manager keeps using it."
"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."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
