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

"An excellent solution that is easy and intuitive to implement."
"Nagios has good scalability."
"The solution is pretty stable."
"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"I would recommend this solution because it's so powerful with no limitation, especially when using the XI version."
"Since the cost is zero and it can use a fairly cheap server to run on the ROI is nearly immediate."
"The most valuable feature of Nagios XI is customization. We can customize based on our requirements. We can do modifications and implement a lot of scripts. Additionally, it is easy to use."
"It provides an easy and powerful solution to network monitoring so I can pay attention to other concerns."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"The network monitoring and configuration within this solution is very good."
"This solution has screens that are easy to understand and provide a wealth of information."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"The support from Pandora FMS is legendary."
"Pandora FMS (the Flexible Monitoring System) is an all-in-one package solution, and we can monitor our whole system with Service perspective."
"The network monitoring and configuration within this solution is very good."
"The most valuable features are auto-discovery and automatic detection of the network topology and network monitoring."
 

Cons

"I feel that the maturity and user interface needs to be improved."
"The GUI could be improved."
"This solution would be improved with the inclusion of additional services. Monitoring streaming services is an example of something that is not currently supported, so in order to handle this, I would have to write a script."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough. You need to read some tutorials or be trained to understand what it's displaying. Also, I think it needs more features to improve network visibility because there are some things you can't detect."
"I would like to see support for notification via SMS."
"Nagios needs to improve their incident manager. Currently, it isn't good for ITIL in my opinion."
"Backup mechanisms and some kind of templating system for dashboards are needed."
"Its simple deployment but complexity comes once you have to import more plugins."
"I sincerely believe that Pandora needs new ideas for functionality closer to advanced device security monitoring."
"We would like the real-time monitoring of an interface to be improved within this solution."
"I find that this software is resource heavy, and demands a lot of processing capacity."
"I think some improvements to the Android app would be good."
"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."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"The product lacks APIs for integration with other systems."
"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."
 

Pricing and Cost Advice

"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."
"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 Core does not have any payment, but Nagios XI requires payment for the license."
"Nagios XI is an expensive solution."
"Nagios XI is open source."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"We are using the free version of this solution."
"Growing the solution or migrating to the Enterprise version is easy, and various plans are available."
"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."
"You get the license and it includes updates, new versions, and access to the complete library of modules."
"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."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"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."
