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

"You want to monitor a specific metric that nobody else has? You can do it even with the most basic of scripting skills, and you can always share it with the vast community of Nagios Exchange."
"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."
"Simplicity of configuration; I can set up configuration of 100 devices with about 10 services in one to two days."
"The most valuable feature is its support for different types of devices, where it can use all of the equipment that you need."
"It's an essential part of our infrastructure, and we'll keep using it."
"Nagios allows us to configure any device so that we can send pager alerts when people don't have access to emails. It also allows us to schedule downtime and maintenance."
"Nagios is a custom API manager, and we can expose custom APIs for our integration. This is a great feature."
"The solution has a lot of plugins and scripts integrated with it."
"The monitoring system within this solution is very good. It is easy to use and navigate, and makes issue alarms easily viewable."
"Thanks to this software and to the work of the support team, we have everything under control."
"The solution is so lightweight that with only 4GB of ram, it allows keeping track of up to two hundred agents from a single console."
"Pandora FMS provides us with a general report (graphical) about all of the connected devices, which helps with planning new stations and tracking them."
"This product has allowed us to identify and correct certain issues that were affecting our solution."
"I like this solution a lot because it has a very large Hispanic community and the platform looks very friendly."
"Thanks to its flexibility, I have been able to adapt the tool to our servers and find out quickly how their console works."
"The support from Pandora FMS is legendary."
 

Cons

"WebUI should be improved (visual aspect) and should incorporate non-relational databases."
"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."
"Nagios XI can improve its GUI for users with a new look."
"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 pricing has recently risen. I know they've changed what is covered under the license, however, it doesn't change the way we use it and adds nothing to our experience, and yet we now have to pay more."
"While the UI is functional, I have always thought there was room for improvement here."
"The way Nagios displays information isn't easy for a new user to understand. It's not intuitive enough."
"Improve the documentation, examples, and best practices, therefore users can understand how to do things."
"An update to the Android app would be appreciated."
"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."
"I would like to have a dashboard with all assets displayed, with a quick hover-over status."
"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."
"We would like the real-time monitoring of an interface to be improved within this solution."
"Improvements are needed for server and network discovery, including service-based discovery."
 

Pricing and Cost Advice

"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."
"As it is not an agentless tool, I think it is expensive."
"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."
"Nagios XI is an expensive solution."
"You can grow into the higher-priced scale as they learn how to utilize the features for Nagios XI."
"The pricing is really cost efficient. The licensing is perpetual and can be renewed very easily."
"We are using the free version of this solution."
"Only one payment and it includes support, updates, new versions, and access to the complete library of plugins except for SAP and z/OS."
"The open-source version offers 100% functionality and the hardware requirements for a solution like this one are very modest."
"The Open Source Community Edition is great to just explore the software, or use it on medium-sized infrastructures."
"In terms of money, the Enterprise version is the cheapest that I have found after a market study."
"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."
"Pandora FMS is easy to implement and the pricing of licenses is competitive."
"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."
