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 helped me to draw the network and check for system failures."
"Overall, it's a powerful system."
"I really found Nagios a perfect fit for us and a good product to work with."
"It's an essential part of our infrastructure, and we'll keep using it."
"The most valuable feature is the dashboard, where I can have a single screen that provides a summary for hundreds of servers."
"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"The product allows comprehensive monitoring of your environment, from basic monitoring of your servers health to more complex tasks like AD, database, and, to some extent, application-level monitoring."
"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."
"This tool has been of great help because we can manage faster solutions with the problems in our network and it helped us reduce our response time."
"Thanks to this software and to the work of the support team, we have everything under control."
"What I value most about Pandora FMS is the simplicity of working with it."
"The administration of the console is very easy. I like that Pandora FMS is interactive and easy to manage."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"The network monitoring and configuration within this solution is very good."
"In comparison with most monitoring software, this software is incredibly easy to use."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
 

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."
"We are implementing our hybrid cloud strategy, and it will most likely not be suitable for monitoring our public cloud assets."
"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."
"We're still experiencing stability issues with regards to collecting performance graphs."
"The installation can get very difficult depending on what Linux flavour you are using."
"They need more documentation for the plugins."
"The Configuration Wizard needs improvement, because not all vendors are present."
"The interface could be more user-friendly."
"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."
"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 such as Universal CMDB."
"Pandora FMS is relatively new, and the interface with the older version crashes at times. We have several different operating systems, such as Linux and Windows, and Pandora does not run as well in these."
"Their support is good, but it is just online communication. It would be great to be able to just call someone and talk to them instead of always writing. It works well for me because I am a decent communicator in email, but some people might find it difficult to describe in a written fashion and communicate with them that way. There is a learning curve to the interface, but once you get used to it, it is actually very powerful. They have a lot of options, but people struggle with the interface. They've improved it though, and it is getting better. They need to keep improving the learning curve to help buy-in. I'm the guy that manages it, so I'm comfortable with it. They can refine the upgrade agents to be easier. 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. It has a complete GUI and everything."
"Pandora FMS is an overall great monitoring solution, but it does not have a community that is as large as Zabbix or Nagios."
"Pandora FMS is relatively new, and the interface with the older version crashes at times."
 

Pricing and Cost Advice

"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 an expensive solution."
"The licensing fees for this solution are approximately $3,000 USD per year."
"The pricing is high with separate licensing for the product and support."
"As it is not an agentless tool, I think it is expensive."
"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."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"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."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"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."
"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."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."

Nagios vs. Zabbix vs. PRTG vs. Spiceworks vs. Solarwinds Network Performance Monitor
I have researched a quite a few network monitoring tools which can be used for various monitoring purposes of not only the servers, but the intermediate routers as well. There are majorly three types of these softwares. Ones which are completely open-source, you can do almost anything you want…
